What are Standard Wall Oven Sizes?


Standard wall ovens are typically classified as 24″, 27″, or 30″ wide (60, 68 or 76 cm), although these are approximate measurements that vary slightly depending on the exact model. For example, an oven may be listed as 30″ (76 cm) wide, though it may in fact be 29¾″ (75.5 cm). 

The height and depth of wall ovens can also vary, depending on the model and style, with various configurations available.

It is also important to pay attention to the different installation options, such as:


A unit installed in a standard application will sit proud or sit forward of the surrounding cabinetry or countertop.


In a flush inset installation, the front or top of the unit sits flush or on the same plane as the surrounding cabinetry or countertop.

In determining the cabinet cut-out, you will need to consider whether your appliances will be mounted proud or flush. Not all appliances can be installed flush. If your appliances can be installed flush, you will need a larger cut-out than if you intend to mount them proud. However, you should always refer to the manufacturer’s installation guide.

Generally, it’s most important to consider the size of the opening or cut-out needed for installation. Single wall ovens, double wall ovens, or combination wall ovens and microwaves with varying capacities and dimensions are available.

How Do I Measure My Current Wall Oven Cut-out Dimensions?


Step 1: Remove your current wall oven

The wall oven you currently have should be removed from the cabinet cut-out or wall to ensure precise measurements.

Step 2: Measure the cut-out width

Use a measuring tape to determine the width of the cut-out from edge to edge.

Step 3: Measure the cut-out depth

To determine the depth of your wall oven cut-out, measure from the wall to the front of the cabinet face, excluding the cabinet door. A typical cabinet depth is 24(60 cm).

Step 4: Measure the cut-out height

Take note of the distance between the top of the cut-out opening and the bottom to determine the height of the cut-out. This distance will differ greatly between a single wall oven and a double wall oven.

What Else Should I Consider Before Buying a Wall Oven?


After determining the amount of space you have for an oven, there are a number of considerations to make sure you’re choosing the right one.

You can choose from a range of styles and features to manage mealtime the way you prefer.

Internal oven capacity

In general, a wall oven’s capacity is related to its dimensions, ranging from space-saving units with a capacity of around 3.0 cubic feet to large units of 10 cubic feet or more.

Typically, a larger wall oven means more cooking capacity while a smaller oven means less internal cooking space.

There are several possible capacities for single wall ovens:

  • 24(60 cm) wall ovens: May give you around 2-3 cubic feet of cooking space. 
  • 27 (68 cm) wall ovens:  Generally pack a little more capacity with around 4 cubic feet inside. 
  • 30 (76 cm) wall ovens: Usually offer capacities between 4.7 and 5.1 cubic feet. Alternatively, you can also find 30″ (76 cm) models with reduced heights to offer just enough extra cooking space for 1-2 dishes at a time with around 1.7 cubic feet of capacity.

The capacity listed for each side on a double wall oven is usually double the listed capacity for each width. For instance, a 27 (68 cm) double oven may include two 4.3 cubic foot spaces totalling 8.6 cubic feet.

Fuel type

Your current set-up may dictate the fuel type you choose, so check before shopping for a new oven. You can find gas wall ovens or electric wall ovens in a variety of sizes.

If both will work for your kitchen, take the time to learn the difference between electric and gas ovens so that you can choose the one that will best meet your needs for cooking.

Features and Settings

Here are three settings and features to consider depending on your model and brand:

Convection bake

To help keep a constant temperature inside the oven, convection ovens typically have a fan that circulates hot air. A true convection system also includes a third heating element.

Fit guarantees

Depending on the manufacturer, some components may be guaranteed to fit perfectly. A separate kit allows customizing wall oven installation to coordinate with existing cabinets through its flexible design elements.

Smart features

You can remotely preheat a connected wall oven with your smartphone. You can also adjust things like cook time or temperature by speaking on your voice-enabled device if you don’t have both your hands free.
