Square Footage Calculator
Calculate the square footage of rooms, houses, or any area with our comprehensive calculator. Perfect for flooring projects, painting estimates, property measurements, and construction planning.
Step 1: Area Dimensions
Square Footage Basics
Square footage is calculated by multiplying length by width. For complex shapes, divide them into simple rectangles, calculate each area separately, then add them together.
Step 2: Calculation Options
About Waste Factor
The waste factor accounts for cutting losses, pattern matching, and material imperfections. Typically 5-15% for flooring and 10-20% for tiling projects. Higher percentages for complex patterns or irregular rooms.
