Enter the size of the cabinet and the depth of the cabinet into the calculator to determine the minimum ceiling height/clearance to fit the cabinet.

Ceiling Height Clearance Formula

The following equation is used to calculate the Ceiling Height Clearance.

CH = SQRT(L^2+D^2)

  • Where CH is the minimum ceiling height (ft)
  • L is the length/height of the cabinet/dresser (ft)
  • D is the depth of the cabinet/dresser (ft)

To calculate the minimum ceiling height clearance, add the value of the height of the cabinet squared and the depth of the cabinet squared together, then take the square root of the result.

What is a Ceiling Height Clearance?


A ceiling height clearance is defined as the minimum height a ceiling can be in order to fit a dresser/cabinet.

How to Calculate Ceiling Height Clearance?

Example Problem:

The following example outlines the steps and information needed to calculate Ceiling Height Clearance.

First, determine the length of the cabinet. In this example, the cabinet has a length of 6ft.

Next, determine the depth of the cabinet. This cabinet has a depth of 2.5ft.

Finally, calculate the ceiling height clearance using the formula above:

CH = SQRT(L^2+D^2)

CH = SQRT(6^2+2.5^2)

CH = 6.5 ft.
