How to Use This Calculator

1

Measure Room Dimensions

Use a tape measure to determine the length and width of the room or space in feet. For accuracy, measure along the floor at the baseboard level.

2

Enter Measurements

Input the length and width into the calculator. For irregular shapes, break the space into rectangles and calculate each section separately.

3

Calculate Total Square Footage

The calculator multiplies length × width to give you the square footage. For multiple rooms or sections, add the individual square footages together.

4

Apply to Your Project

Use the square footage to estimate materials for flooring, paint coverage, HVAC sizing, or real estate valuations. Always add 5-10% extra for waste when ordering materials.
