CALCULATE →Flooring Estimate Tips
Measure each room separately
Don't add room sizes in your head. Measure each room individually and calculate one at a time, then add the totals together.
10% waste is the minimum
Diagonal installs and complex cuts can need 15–20% extra. Our calculators use 10% by default. Increase it manually for tricky layouts.
Buy from the same batch
Flooring can vary slightly between production batches. Once you know your quantity, buy it all at once from the same lot number.
Not sure of your square footage?
Use our Square Footage Calculator first to measure your room. It supports rectangles, circles, triangles, and more. Then bring that number to any flooring calculator.
Square Footage Calculator →Frequently Asked Questions
How do I calculate how many boxes of flooring I need?
Measure your room length and width in feet, multiply to get square footage, and add 10% for waste. Divide the total by the coverage per box listed on the packaging. For example, a 12×14 room is 168 sq ft; with 10% waste that is 185 sq ft. If each box covers 20 sq ft, you need 10 boxes. Always buy an extra box from the same lot for future repairs.
What waste factor should I use for flooring?
Use 10% for straight-lay flooring in rectangular rooms. Use 15% for diagonal installs or rooms with many angles, alcoves, and cuts. Use 15 to 20% for large-format tiles (24×24 and bigger) because more material is lost at edges. Our calculators apply 10% by default; increase your order manually for complex layouts.
What is the difference between laminate and luxury vinyl plank (LVP)?
Laminate has a fiberboard core with a photographic layer and a wear layer on top. It looks great but is not waterproof and swells if water gets under the joints. Luxury vinyl plank has a 100% plastic core and is fully waterproof throughout, making it suitable for bathrooms, kitchens, and basements. LVP is also softer underfoot and quieter. Both click-lock into place without glue.
