Choosing the right size commercial pizza oven is about more than finding an oven that fits in your kitchen.
You need an oven large enough to handle your busiest service without creating long ticket times, but buying far more oven than your restaurant needs can waste valuable kitchen space and money.
So what size pizza oven should you buy for your restaurant?
Start with three questions:
- What size pizzas will you make?
- How many pizzas will you need to cook at the same time?
- How many pizzas do you expect to sell during your busiest hour?
A café selling a handful of 12-inch pizzas each evening may be perfectly comfortable with a compact countertop pizza oven. A dedicated pizzeria producing dozens of 16-inch pizzas during a Friday dinner rush may need a large commercial deck oven with two baking chambers.
The right oven size should be based on your peak pizza production, not simply the number of seats in your restaurant.
Nishi Enterprise carries commercial pizza ovens ranging from compact Waring countertop units to large Bakers Pride single- and double-deck ovens for high-volume pizza production.
Commercial Pizza Oven Sizes at a Glance
| Pizza Operation | Possible Starting Point | Best For |
|---|---|---|
| Occasional pizza service | Compact countertop oven | Cafés, bars, small restaurants |
| Small pizza menu | Single or double-deck countertop oven | Restaurants where pizza is a secondary item |
| Moderate pizza volume | Commercial single-deck oven | Italian restaurants and smaller pizzerias |
| Busy pizza operation | Large single deck or double deck | Pizzerias, takeout and delivery |
| High-volume pizzeria | Large double-deck or stacked deck ovens | Continuous peak-hour production |
These are starting points rather than fixed rules. Your actual requirements depend on pizza diameter, baking time, deck dimensions, menu, and peak demand.
Do Not Choose a Pizza Oven Based Only on Restaurant Size
A 100-seat restaurant does not automatically need a larger pizza oven than a 40-seat restaurant.
Consider two businesses.
Restaurant A seats 120 guests but pizza represents only 10% of sales.
Restaurant B seats 40 guests but specializes in pizza, takeout, and delivery.
Restaurant B may need considerably more pizza oven capacity despite having one-third as many dining room seats.
The better measurement is:
How many pizzas will the kitchen need to produce during peak service?
Start With Your Pizza Diameter
Pizza size has an enormous effect on oven capacity.
Common commercial pizza sizes include:
- 10 inches
- 12 inches
- 14 inches
- 16 inches
- 18 inches
An oven deck that can fit several 10-inch pizzas may fit significantly fewer 18-inch pizzas.
Before comparing ovens, finalize your planned pizza sizes.
Then compare those pizza diameters with the oven's usable baking chamber or deck dimensions.
Why Deck Dimensions Matter More Than Exterior Oven Width
A common mistake is looking at an oven's overall width and using that number to estimate capacity.
What matters is the size of the space where the pizza actually cooks.
For example, one Bakers Pride commercial deck oven sold by Nishi has a 36-inch wide by 24.5-inch deep baking chamber, while larger Super Deck models offer substantially larger baking areas.
The outside cabinet will always be larger than the actual cooking surface.
When comparing commercial pizza ovens, look for specifications such as:
- Deck width
- Deck depth
- Deck height
- Number of decks
- Overall oven dimensions
How Many Pizzas Can Fit in the Oven?
Once you know the deck dimensions and pizza diameter, you can begin estimating batch capacity.
However, do not calculate capacity by trying to mathematically squeeze as many circles as possible onto the deck.
Cooks need room to:
- Launch pizzas
- Rotate pizzas
- Move pizzas into hotter or cooler areas
- Check crust development
- Remove finished pizzas
An oven that could technically fit six pizzas might be much easier to operate with five.
Practical capacity is more important than theoretical capacity.
Think About Pizzas Per Hour
This is one of the most useful ways to size a commercial pizza oven.
Suppose your average pizza takes approximately 8 minutes to bake.
If your oven comfortably holds four pizzas at once, the theoretical production rate would be:
4 pizzas × approximately 7.5 baking cycles per hour = approximately 30 pizzas per hour
Real production will generally be lower because employees need time to load, rotate, unload, recover, and manage different orders.
The point is not to calculate an exact production promise.
The point is to determine whether your oven has enough capacity for the rush.
Size for Your Busiest Hour, Not Your Average Hour
Imagine your restaurant sells 100 pizzas per day.
That number alone does not tell you what size oven you need.
If those 100 pizzas are spread evenly across 10 hours, the workload may be manageable.
But if 45 pizzas are ordered between 6:00 and 7:00 p.m., your oven needs to handle that concentrated demand.
Look at:
- Lunch rush
- Dinner rush
- Friday and Saturday volume
- Takeout orders
- Delivery orders
- Catering orders
- Large party orders
Size the oven around the periods when demand is highest.
A Simple Pizza Oven Sizing Formula
A useful starting calculation is:
Peak pizzas per hour ÷ realistic baking cycles per hour = pizzas needed per batch
For example, suppose you expect to sell 40 pizzas during your busiest hour.
If your average pizza requires approximately 8 minutes in the oven, you may have roughly seven complete baking cycles available within that hour after allowing for normal handling.
That means you would want enough practical deck space to handle approximately:
40 ÷ 7 = about 6 pizzas per batch
You would then look for an oven configuration that can comfortably accommodate the required pizza diameter at that production level.
This is a planning exercise rather than an exact performance guarantee because actual cooking times and production rates depend on the oven and pizza.
When Is a Small Countertop Pizza Oven Enough?
A compact countertop oven can work very well when pizza is not the restaurant's primary product.
This may include:
- Bars
- Cafés
- Small restaurants
- Hotels
- Concession operations
- Delis
- Restaurants adding a limited pizza menu
For example, a bar selling pizzas primarily as an appetizer or late-night option may not need a large floor-model deck oven.
Nishi carries compact Waring commercial pizza ovens, including single- and double-deck countertop configurations.
When Should You Buy a Double-Deck Countertop Oven?
A double-deck countertop model can provide additional production without requiring the floor space of a traditional large deck oven.
It may be useful if:
- Counter space is available
- Pizza volume is moderate
- You regularly need to cook two or more pizzas simultaneously
- You want more production than a single-deck compact oven offers
- Pizza remains a secondary rather than primary menu category
This can be a good middle ground between a very small pizza oven and a large dedicated pizzeria setup.
When Should You Move to a Floor-Model Deck Oven?
Once pizza becomes a major menu category, a larger commercial deck oven starts to make more sense.
Consider a floor-model deck oven when:
- Pizza is a major percentage of sales
- You regularly cook several pizzas simultaneously
- You sell larger pizzas
- Takeout volume is significant
- Delivery is important
- You experience concentrated dinner rushes
- The countertop oven would operate near maximum capacity for long periods
Bakers Pride deck ovens in the Nishi pizza oven collection are available in several baking chamber sizes and single- or double-deck configurations.
What Size Deck Oven Does a Small Pizzeria Need?
A smaller pizzeria may be comfortable with one commercial baking chamber if the deck provides enough space for the restaurant's pizza diameter and peak demand.
A single-deck oven may work well when:
- Sales volume is moderate
- Most pizzas are 12 to 14 inches
- Takeout volume is manageable
- The kitchen does not experience severe order spikes
However, do not buy a small single deck simply because your restaurant is new.
If your business plan depends heavily on pizza sales, buying barely enough capacity on opening day may cause problems as soon as demand grows.
When Does a Restaurant Need a Double-Deck Pizza Oven?
A double-deck oven becomes attractive when one baking chamber is not enough to handle peak production comfortably.
Double decks can provide:
- More simultaneous pizza capacity
- More production per square foot of floor space
- Ability to divide production between two chambers
- Potential to operate decks differently when the specific oven allows it
This can be particularly useful for:
- Busy pizzerias
- Delivery restaurants
- Pizza-by-the-slice operations
- Italian restaurants with strong pizza sales
- High-volume takeout businesses
Nishi carries large Bakers Pride double-deck ovens with two independently usable baking chambers for high-volume commercial pizza production.
Why Two Decks Can Be Better Than One Giant Deck
More baking area is useful, but independent chambers can also provide operational flexibility.
For example, a restaurant might use:
Upper Deck: traditional pizzas
Lower Deck: thicker crusts, specialty pizzas, or additional rush-hour production
Depending on the oven, independent controls can allow different operating conditions between decks.
Another advantage is vertical space.
Stacking production vertically allows the restaurant to increase capacity without doubling the amount of floor space used by the oven.
What About Extremely Large Deck Ovens?
Large commercial Super Deck ovens can provide significantly more baking surface than compact restaurant ovens.
For example, Nishi carries Bakers Pride models with baking chambers as large as approximately 45 by 34.5 inches and even wider electric configurations with 57-inch baking chambers.
These ovens are designed for kitchens where substantial pizza production is expected.
They may be appropriate for:
- Dedicated high-volume pizzerias
- Busy delivery operations
- Large Italian restaurants
- Hotel kitchens
- Institutional foodservice
- Banquet and catering production
Do not purchase this much oven simply because it is available.
Large deck ovens require substantial space, utilities, and investment.
What Size Oven Do You Need for 12-Inch Pizzas?
Twelve-inch pizzas are relatively easy to accommodate in many commercial pizza ovens.
A compact oven may be sufficient when sales volume is low.
For higher volume, the larger issue becomes how many 12-inch pizzas need to bake simultaneously.
For example:
- 1 to 2 pizzas at once: compact equipment may work
- Several pizzas at once: larger countertop or deck oven
- Continuous high-volume production: large single or double deck
Again, compare the actual usable deck dimensions with your required batch size.
What Size Oven Do You Need for 16-Inch Pizzas?
Sixteen-inch pizzas require substantially more deck area than 12-inch pizzas.
A compact countertop oven that works perfectly for small pizzas may only accommodate one large pizza at a time.
If 16-inch pizzas are a major part of your menu, deck dimensions become especially important.
Before buying, determine:
- How many 16-inch pizzas fit comfortably
- How much space remains for rotating them
- Whether the oven opening is large enough
- Whether the chamber depth provides sufficient working room
What Size Oven Do You Need for 18-Inch Pizzas?
Large 18-inch pizzas can quickly eliminate smaller ovens from consideration.
A pizzeria selling a large number of 18-inch pies should look closely at commercial floor-model deck ovens with adequate width and depth.
Do not assume that because an oven can fit one 18-inch pizza, it is appropriate for a busy operation.
If you need to cook four or six large pizzas simultaneously, the required deck area becomes much greater.
Pizza Style Changes the Size You Need
Pizza diameter is not the only consideration.
Different pizza styles can have different baking times.
A pizza that cooks quickly frees up deck space faster than one that needs a longer bake.
Consider:
- Thin-crust pizza
- New York-style pizza
- Pan pizza
- Deep-dish pizza
- Thick-crust pizza
- Flatbreads
A longer cooking time means each pizza occupies the oven for longer, reducing hourly production.
Chamber Height Can Matter Too
Most people think about oven width and depth but forget about chamber height.
If you plan to cook:
- Deep-dish pizzas
- Tall pan pizzas
- Calzones
- Bread
- Other baked foods
make sure there is adequate vertical clearance inside the oven.
This is particularly important if the pizza oven will be used for more than one menu category.
Single Oven vs. Two Separate Pizza Ovens
A restaurant requiring additional capacity has another choice:
One larger oven or two smaller ovens?
One large oven can:
- Consolidate production
- Simplify the station
- Provide substantial deck space
Two separate ovens can:
- Provide more production flexibility
- Allow different oven settings
- Provide some redundancy
- Allow one oven to remain off during slow periods
If pizza represents the majority of your sales, redundancy may deserve serious consideration.
What Happens If Your Only Pizza Oven Goes Down?
If pizza is just one item on a large restaurant menu, losing the pizza oven temporarily may be inconvenient.
If you operate a pizzeria, losing your only oven can effectively stop the business.
This is one reason high-volume operators may prefer:
- A double-deck oven
- Two ovens
- Multiple stackable decks
Capacity planning should consider equipment reliability and operational risk as well as normal sales volume.
How Much Extra Pizza Oven Capacity Should You Buy?
Buying an oven that operates at 100% capacity during every dinner rush leaves very little room for unexpected demand.
Consider enough additional capacity for:
- Future sales growth
- Large takeout orders
- Delivery surges
- Catering
- Weekend demand
- Special events
However, there is no reason to buy an enormous double-deck oven if the restaurant realistically expects to make ten pizzas per day.
Plan for reasonable growth rather than maximum imaginable demand.
Do Not Forget Takeout and Delivery
Dining room size is becoming an increasingly poor way to estimate kitchen production.
A 50-seat restaurant can receive another 30 orders online while every dining room table is occupied.
If your restaurant plans to offer:
- Online ordering
- Third-party delivery
- Pickup
- Catering
include those sales when calculating oven capacity.
Your oven has to cook pizzas for every sales channel at the same time.
Countertop Pizza Oven Size Guide
Countertop ovens are a good fit when production demands are relatively modest.
Nishi currently carries several Waring options ranging from smaller single-deck models to larger commercial configurations.
Consider a countertop oven when:
- You only need one or two pizzas cooking at once
- Pizza is a secondary menu category
- Floor space is extremely limited
- You want to add pizza without redesigning an entire cook line
Before choosing one, confirm the maximum pizza diameter supported by the specific model.
Floor Pizza Oven Size Guide
A full-size deck oven is more appropriate when your production demands exceed what countertop equipment can comfortably handle.
Large Bakers Pride models offer much greater baking surface and are available in different chamber dimensions.
For example, Nishi's current assortment includes models with baking chambers around:
- 36 inches wide by 24.5 inches deep
- 45 inches wide by 34.5 inches deep
- 57 inches wide by 36 inches deep
Exact dimensions vary by model.
This is why there is no single "standard commercial pizza oven size."
Do You Need a 36-Inch, 45-Inch, or 57-Inch Deck?
Think about the number and diameter of pizzas rather than focusing on the number itself.
Smaller Commercial Deck
A smaller deck may be sufficient for a restaurant with moderate volume and smaller pizzas.
Advantages can include:
- Smaller footprint
- Lower initial investment
- Enough capacity for moderate production
Mid-Size Commercial Deck
A larger deck allows several pizzas to be managed simultaneously and provides more room for repositioning pizzas during the bake.
This can be useful for a dedicated pizzeria with steady volume.
Very Large Commercial Deck
A wide and deep deck provides substantial capacity for large or high-volume operations.
However, the oven itself also becomes much larger and may require substantial utility and ventilation planning.
Measure Your Kitchen Before Choosing an Oven
Once you determine the baking capacity you need, make sure the oven physically works in the kitchen.
Measure:
- Available width
- Available depth
- Ceiling height
- Doorways
- Hallways
- Delivery route
- Working aisle in front of the oven
- Required installation clearances
A pizza oven can be one of the largest appliances in the kitchen.
Do Not Forget Pizza Peel Space
Floor space in front of a deck oven is especially important.
A pizza cook needs enough room to operate a peel comfortably.
The employee must be able to:
- Approach the oven
- Open the door
- Insert the peel
- Launch the pizza
- Rotate the pizza
- Retrieve the pizza
- Turn toward the cutting or landing station
A massive oven installed in a narrow aisle may be much harder to operate than the floor plan suggests.
Plan the Entire Pizza Station, Not Just the Oven
The oven cannot produce pizza by itself.
You also need space for:
- Dough
- Sauce
- Cheese
- Toppings
- Pizza peels
- Pans or screens
- Cutting
- Boxing
- Finished pizza landing
A commercial pizza prep table can keep refrigerated toppings organized directly beside the assembly area.
A well-designed station might flow like this:
Dough → Stretch → Sauce and Toppings → Oven → Cut → Box or Serve
Does a Larger Oven Mean You Need a Larger Pizza Prep Table?
Often, yes.
There is little benefit in purchasing an oven capable of producing 50 pizzas per hour if your prep station can only assemble pizzas slowly enough to feed half that capacity.
Production needs to remain balanced.
If the oven is upgraded, think about whether you also need:
- More refrigerated topping capacity
- More dough storage
- A longer prep surface
- Additional employees
- More pizza peels
- More cutting and boxing space
Nishi Enterprise carries pizza prep refrigerators in multiple widths for different production volumes.
Could a Dough Sheeter Increase Pizza Production?
If dough preparation becomes the bottleneck, some restaurants may consider a commercial dough sheeter or pizza dough roller.
This equipment can help process dough to a more consistent thickness and reduce some repetitive manual preparation.
Whether it is appropriate depends on your pizza style. Some pizzerias deliberately hand stretch every dough ball and would not want a sheeter as part of their process.
Gas vs. Electric Does Not Determine Physical Oven Size
Both gas and electric commercial deck ovens are available in substantial sizes.
Choose fuel type based on:
- Available utilities
- Electrical capacity
- Gas capacity
- Equipment specifications
- Operating needs
- Installation requirements
Nishi carries both gas and electric commercial pizza ovens.
Check Utilities Before Ordering a Large Oven
The larger the oven, the more important utility planning becomes.
Before purchasing a gas oven, confirm:
- Fuel type
- Gas input
- Gas pressure requirements
- Pipe capacity
Before purchasing an electric oven, confirm:
- Voltage
- Phase
- Amperage
- Required circuit
- Hardwire or plug requirements
Large commercial deck ovens can have substantial utility requirements.
Check Ventilation Requirements Too
Do not order the oven and then figure out ventilation afterward.
The oven's listing, fuel source, installation, and local requirements may affect ventilation.
Confirm:
- Manufacturer installation instructions
- Required clearances
- Ventilation requirements
- Local mechanical requirements
- Applicable fire requirements
before finalizing the kitchen plan.
Example 1: Small Café Adding Pizza
Suppose a café wants to add three pizzas to its menu.
The owner expects:
- 10 to 20 pizzas per day
- Mostly 12-inch pizzas
- No delivery program
- Relatively light dinner volume
A compact commercial countertop pizza oven may make much more sense than installing a massive floor-model deck oven.
The restaurant gets enough production without sacrificing excessive kitchen space.
Example 2: Full-Service Italian Restaurant
Now imagine a full-service Italian restaurant where pizza accounts for a substantial percentage of dinner sales.
The restaurant offers:
- 12-inch pizzas
- 16-inch pizzas
- Dine-in
- Takeout
During peak service, the kitchen may need several pizzas baking simultaneously.
A larger single-deck floor oven may be appropriate, or a double deck could provide additional room for growth and busy weekend service.
Example 3: Dedicated Pizzeria
A dedicated pizzeria may receive dozens of orders during a short Friday dinner rush.
Pizza is not one part of the menu. It is the business.
In that situation, oven capacity directly affects:
- Ticket times
- Delivery times
- Customer satisfaction
- Maximum sales per hour
A large double-deck commercial pizza oven or multiple deck ovens may be necessary.
Example 4: High-Volume Delivery Pizzeria
Delivery creates a unique challenge because orders can arrive in large bursts.
A dining room naturally limits the number of customers who can order simultaneously.
Online ordering does not.
A pizzeria could receive 20 orders within a few minutes.
If each order contains two pizzas, the oven suddenly has 40 pizzas waiting.
High-volume delivery businesses should therefore leave more production headroom than restaurants relying mainly on dine-in customers.
What Happens If Your Pizza Oven Is Too Small?
An undersized oven can create:
- Long ticket times
- Delayed delivery orders
- Large order backlogs
- Overcrowded oven decks
- Difficulty rotating pizzas
- Pressure on kitchen employees
- Lost sales during peak periods
When every inch of deck space is occupied continuously, the oven has become a production bottleneck.
What Happens If Your Pizza Oven Is Too Large?
Oversizing also has disadvantages.
An unnecessarily large oven can mean:
- Higher purchase cost
- More kitchen space consumed
- Larger utility requirements
- More installation complexity
- Capacity that rarely gets used
The goal is not to buy the biggest pizza oven you can afford.
The goal is to buy enough capacity to comfortably handle your expected peak demand with reasonable room for growth.
How Much Future Growth Should You Plan For?
If your calculations suggest your oven will be almost completely full during opening-week peak service, consider moving up in capacity.
You may later add:
- Delivery
- Online ordering
- Catering
- Additional pizza sizes
- New specialty pizzas
- Longer operating hours
Replacing a commercial pizza oven shortly after opening can be far more disruptive than choosing adequate capacity during the original buildout.
Pizza Oven Sizing Checklist
Before purchasing, answer all of these questions:
- What is our largest pizza diameter?
- What is our most common pizza diameter?
- How long does the pizza take to bake?
- How many pizzas do we expect during our busiest hour?
- How many pizzas need to bake simultaneously?
- How much usable deck space does the oven provide?
- Do we need one deck or two?
- Will we offer takeout?
- Will we offer delivery?
- Will we offer catering?
- How much future sales growth do we expect?
- How much kitchen space is available?
- Is there enough room in front for pizza peels?
- Do we have the required gas or electrical service?
- What ventilation does the oven require?
What Size Pizza Oven Should You Buy?
A practical starting point is:
- Small café, bar, or limited pizza menu: commercial countertop pizza oven
- Restaurant with moderate pizza sales: larger countertop or single-deck commercial oven
- Small dedicated pizzeria: commercial floor-model deck oven
- Busy pizzeria: large single deck or double deck
- High-volume delivery or takeout operation: large double deck, stacked ovens, or multiple production ovens
But those categories are only a starting point.
The best way to size the oven is to determine your pizza diameter, expected cooking time, practical batch capacity, and peak hourly sales.
Then choose enough deck space to comfortably handle the rush.

Frequently Asked Questions
What size commercial pizza oven do I need?
Choose an oven based on the diameter of your pizzas, how many need to bake at the same time, their cooking time, and how many pizzas you expect to sell during peak service. Small restaurants may be comfortable with a countertop oven, while dedicated pizzerias often need larger deck ovens.
How many pizzas should a commercial pizza oven hold?
There is no universal number. A restaurant selling pizza occasionally may only need capacity for one or two pizzas at a time, while a high-volume pizzeria may need room for several large pizzas across multiple decks.
Is a single-deck pizza oven enough for a restaurant?
It can be. A single deck may provide plenty of production for a small or moderate-volume operation. If peak orders would keep the deck completely full for long periods, a double deck may provide more appropriate capacity.
When should I buy a double-deck pizza oven?
Consider a double deck when pizza volume is high, takeout or delivery creates large order surges, or you need more cooking capacity without doubling the oven's floor footprint.
What size oven do I need for 16-inch pizzas?
Look at the oven's actual usable deck dimensions and determine how many 16-inch pizzas can fit while leaving enough room for employees to load, rotate, and remove them. The correct oven depends on how many 16-inch pizzas you need to produce simultaneously.
What size oven do I need for 18-inch pizzas?
Large 18-inch pizzas require significant deck area. Restaurants producing them in volume should generally compare larger commercial floor-model deck ovens rather than compact units designed primarily around smaller pizzas.
How do I calculate pizza oven capacity?
Estimate the number of pizzas required during your busiest hour, determine the average baking time, estimate how many complete baking cycles are realistic per hour, and calculate how many pizzas must fit comfortably in each batch.
Should I buy a larger pizza oven for future growth?
Some additional capacity is usually sensible if pizza sales are expected to grow. However, drastically oversizing the oven can increase purchase cost, utility requirements, and kitchen space without providing meaningful operational benefit.
Is a countertop pizza oven enough for a restaurant?
It can be for cafés, bars, small restaurants, and businesses where pizza is a secondary menu item. A dedicated pizzeria with substantial peak demand will generally need much more production capacity.
Is oven size based on how many seats my restaurant has?
No. Seating capacity can provide context, but pizza sales volume is much more important. A small delivery-focused pizzeria may need a larger oven than a large full-service restaurant that sells relatively few pizzas.
Should I size my pizza oven based on daily sales?
No. Peak-hour demand is more important than daily sales. Two restaurants can sell the same number of pizzas per day but require very different ovens if one receives most of its orders within a short dinner rush.
What else should I buy with a commercial pizza oven?
A complete pizza station may also require a pizza prep refrigerator, dough storage, work tables, pizza peels, pans or screens, cutting space, commercial refrigeration, and possibly a dough sheeter or roller depending on the restaurant's production method.
