Calculate room size using length and width measurements. Quickly estimate total area in square feet, square yards, and square meters for bedrooms, living rooms, offices, and more.
Feet formula:
Room area = length (ft) × width (ft)
Metric formula:
Room area = length (m) × width (m)
This calculator also converts the result into square yards and square meters automatically.
Knowing room size can help with flooring estimates, paint planning, furniture layout, rug sizing, heating and cooling estimates, and general home improvement projects.
Adding extra material is often useful when ordering flooring, carpet, or similar products.
Your result shows the flat floor area of the room based on the measurements entered. This is the standard way room size is measured for planning and estimating purposes.
The adjusted total with extra material can help when ordering flooring, carpet, tile, or other products where cuts, waste, or installation adjustments are expected.
Multiply the room length by the room width. For example, a 12 ft by 10 ft room is 120 square feet.
Break the room into smaller rectangular sections, calculate each section separately, then add the totals.
Square yards are a larger unit of area. One square yard equals 9 square feet.
Yes. Many flooring projects use extra material to account for cuts, waste, and installation adjustments.
