Opening Size for a 27-Inch Wall Oven

Ruth de Jauregui

Determining the size of the opening in a cabinet for a 27-inch oven is a relatively simple process. In most cases, the specifications are available in the owner's manual or online. However, if you are renovating and wish to reuse the existing appliances or have purchased a used wall oven, you need the oven's measurements to frame a new cabinet. The rough-cut opening in the cabinet is designed to fit the dimensions of the body of the oven behind the front panel.

Wall ovens are available in many sizes and shapes.
  1. Measure the width of both the front panel and the oven behind it. Generally, a 27-inch oven is installed in a 27-inch or wider cabinet.

  2. Measure the height of the oven from top to bottom just behind the front panel. Oven heights vary, depending on the manufacturer and the type of wall oven such as a double oven or a conventional, convection or microwave oven.

  3. Measure the oven from the back of the front panel to the back of the oven. Generally, this measurement is between 23 1/2 and 23 7/8 inches, depending on the manufacturer. Therefore, the minimum depth of the oven cabinet is 24 inches. With the width, height and depth of the oven, you can now frame the opening in the kitchen cabinet.
