Frequently Asked Questions
How do I measure square footage for flooring?+
Measure each room's length × width, add all rooms together, and add 10% for waste (cuts and pattern matching). For irregular rooms, break them into rectangles and add the areas.
How many square feet is 1 square meter?+
1 square meter = 10.764 square feet. So a 100 m² apartment is about 1,076 sq ft. This calculator automatically converts between the two units.
Does square footage include walls and closets?+
In real estate listings, square footage is measured from interior walls and typically excludes wall thickness. Closets are included. Unfinished basement, garage, and attic are usually listed separately.
Why add a waste factor for flooring?+
When cutting tiles or planks to fit, you generate waste. For straight-lay tile or plank, add 10%. For diagonal lay or complex patterns, add 15%. For irregular rooms, add up to 20%.
What is the average size of a US home?+
The median new US home is about 2,300 sq ft (214 m²). The average apartment is 900 sq ft (84 m²). A typical 3-bedroom house runs 1,500–2,000 sq ft.
