How to Measure for a Built-In Wall Oven

One of the biggest causes of delays in kitchen remodels isn’t the construction crew or shipping delays—it’s wrong measurements. Homeowners often assume all wall ovens are the same size, but that’s far from the truth. Even being off by half an inch can mean your new oven won’t fit, leading to costly cabinet modifications and frustrating delays.

The good news? With the right tools and a few simple steps, you can measure your wall oven cutout accurately the first time.

Tools You’ll Need

Before you start, grab these essentials:

• A tape measure (flexible, at least 6 feet long)

• A notepad and pencil (or your phone) to record dimensions

• Optional: A level to double-check alignment of your cabinet opening

Step 1: Measure Cutout Width

• Measure across the top, middle, and bottom of the opening.

• Use the smallest number—cabinet openings aren’t always perfectly square.

• Write it down to the nearest 1/16 of an inch.

Step 2: Measure Cutout Height

• Measure from the floor of the cutout to the top trim piece.

• Again, check in at least two spots (left and right) to confirm consistency.

• Note the smallest measurement.

Step 3: Measure Cutout Depth

• Place the tape measure at the front edge of the cabinet and extend it all the way to the back wall.

• Watch for obstructions like electrical outlets or gas lines that might reduce usable depth.

Step 4: Check Surrounding Clearance

Don’t just measure the opening itself—look at what surrounds it:

• Cabinet doors and drawers: Make sure they won’t hit the oven door.

• Trim and molding: Account for decorative pieces that may reduce space.

• Ventilation requirements: Most ovens need a little breathing room around them for proper airflow.

Step 5: Factor in Electrical or Gas Hookup Space

• Ensure there’s enough clearance at the back of the cutout for the electrical junction box or gas line.

• A tight fit against the wall could block the hookup and force modifications.

Step 6: Compare with the Manufacturer’s Spec Sheet

Every wall oven model has a specification sheet that lists exact cutout requirements. Once you’ve got your numbers, compare them to the spec sheet before you buy.

Pro tip: Use a tool like CutoutMatch to instantly find wall ovens that will fit your measured space.

Measuring your wall oven cutout correctly takes just a few minutes, but it can save you days, or even weeks, of frustration during your remodel.
