Getting started

Quick reference
Material pricing
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:
Whole-home flooring averages $6,000-30,000 for a 1,500 sq ft home. Whole-home painting averages $2,000-6,000.
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.
