Getting started
How to Calculate House Square Footage
To calculate house square footage, measure the length and width of every room in feet. Multiply length × width for each room and sum the results. Exclude unfinished basements, garages, and outdoor patios from real estate square footage.
2. Sum all room areas
Multiply length × width for each room. Add all room totals to get house square footage.
3. Use for listings or budgets
Use house area for real estate listings, HVAC sizing, insurance valuation, and whole-home material estimates.
Quick reference
Reference
1 acre = 43,560 square feet
1 square yard = 9 square feet
1 square meter = 10.764 square feet
1 square inch = 0.00064516 square feet
Material pricing
Calculate Cost of Materials
House square footage drives the cost of whole-home renovations. Multiply total area by the price per unit of any material covering the entire home.
There are 2 steps to calculate material cost:
- Enter the price per square foot for flooring, paint, or insulation that covers the full house area.
- The Square Foot Calculator multiplies your house area by the unit price to give the total material cost.
Whole-home flooring averages $6,000-30,000 for a 1,500 sq ft home. Whole-home painting averages $2,000-6,000.
Calculating the Square Footage of a House or Property
Measure the length and width of every rectangular room inside the building. Calculate the area for each room, then add the totals together. Exclude unfinished basements and garages from standard real estate square footage. A house with a 250 sq ft living room, 180 sq ft kitchen, 200 sq ft bedroom, and 50 sq ft bathroom has a total area of 680 square feet.
For rooms with alcoves or closets, measure each rectangular section separately and add the areas. The Square Foot Calculator supports quantity input so you can calculate multiple rooms of the same size at once.
