Quickly calculate the square footage of any room, floor, or outdoor area. Handy for flooring, paint, tiling, and real estate estimates.
This free square footage calculator helps you find the area of rooms, floors, patios, decks, and other spaces. It supports common shapes so you can get accurate estimates for flooring, paint, tiling, or real estate purposes.
Accurate measurements lead to better material estimates and fewer surprises when ordering flooring, paint, or other supplies.
The calculator uses standard geometric formulas. Results are shown in both square feet and square meters so you can use whichever unit is most convenient.
Knowing the exact square footage helps with planning, budgeting, and ordering the right amount of materials.
This calculator gives a precise geometric area based on the dimensions you enter. Always add a waste factor (typically 5β15%) when ordering flooring, tile, or other materials to allow for cuts, mistakes, and future repairs. For official real-estate measurements, follow local standards or consult a professional appraiser.
For a rectangular room, multiply length by width. Use this calculator to handle different shapes and convert between feet and meters automatically.
One square meter equals approximately 10.764 square feet. The calculator shows both units so you can work in the system that matches your materials or local practice.
Treat the space as a large rectangle minus a smaller rectangular cut-out. Enter the overall outer length and width, then the dimensions of the missing section. The calculator subtracts the cut-out area for you.
Include any area that will receive the same material or treatment. For flooring or paint estimates, measure each section and add the results.
Most installers recommend adding 5β10% for simple layouts and 10β15% for complex patterns, diagonal installations, or rooms with many cuts.
Yes. The same formulas work for patios, decks, driveways, and garden beds. Just measure the space and select the matching shape.
