Calculate square footage, square meters or square yards from length and width for floors, walls, rooms and material planning.
How to calculate square footage or area
Measure length and width using compatible units, then multiply them. Use the result to plan flooring, tile, paint, drywall and other area-based materials.
Why this calculator has no price
Area itself is not a purchasable material. Use the calculated area in the related material calculator to estimate quantities and sourced costs.
Frequently asked questions
What is square footage?
Square footage is an area measurement in square feet. Multiply length in feet by width in feet for a rectangle.
Can I calculate square meters too?
Yes. Select metric dimensions and output square meters.
Can I use this result for tile or flooring?
Yes. Use the area as an input to the related material calculator, then add waste and product coverage there.
Why is there no cost on this calculator?
Area has no standalone market price. Costs belong to the material or work applied to that area.
What does Square Footage & Area Calculator calculate?
The calculator uses the measurements and values you enter and applies a defined deterministic formula. Change the inputs and the result is calculated again from those values.
Can I save this calculation to a project?
Yes. After calculating, use “Add to my project estimate” to save the result in your current Calcavera project estimate. You can repeat this with other calculators to build a multi-item project.
Can I print or save the estimate as a PDF?
Yes. Open the saved project estimate, then use the “Print / Save PDF” button. Your browser can print the estimate or save it as a PDF file.
Can I use metric and imperial units?
Yes. Where supported by the calculator, you can mix common metric and imperial input units. Calcavera converts measurements before running the calculation and shows the selected output unit.
