How square footage is calculated

The calculator converts width and length into feet, multiplies them to find square feet, then multiplies by quantity. You can display the area in square feet, square inches, square yards, or square meters.

Enter how many matching areas you want to include. For example, use 2 for two identical rooms or panels.
