Measuring the diagonal of a couch is essential when determining if it will fit through doorways, staircases, or into a room. The Couch Diagonal Measurement Calculator simplifies this process by calculating the diagonal length based on the couch’s length, width, and height. This measurement helps you avoid any surprises during delivery or setup.
Formula
The diagonal measurement (D) is found by taking the square root of the sum of the squares of the length (L), width (W), and height (H). In other words, D equals the square root of (L squared plus W squared plus H squared).
How to use
Input the couch’s length, width, and height into the calculator. After entering the values, click the “Calculate” button. The calculator will instantly show the diagonal measurement of your couch.
Example
Suppose your couch is 80 inches long, 35 inches wide, and 30 inches high. The diagonal measurement will be the square root of (80² + 35² + 30²), which equals approximately 91.65 inches.
