Flooring Calculator
Calculate square footage and boxes of flooring needed with waste factor included.
1 room totaling 180 sq ft. With 10% waste: 198 sq ft ÷ 20 sq ft/box = 10 boxes. Always buy from the same dye lot - keep any extra boxes for future repairs.
Common Questions
How do I calculate how much flooring I need?
Measure each room length times width to get square footage. Add all rooms together. Add 10 percent for waste. Divide the total by the box coverage to find how many boxes to buy.
How much extra flooring should I buy for waste?
Buy 10 percent extra for straight layouts. Buy 15 percent extra for diagonal or herringbone patterns. Irregular rooms or lots of cuts need 15 to 20 percent. It is always better to have extra than to run short.
Why is it important to buy all flooring from the same dye lot?
Flooring from different production runs can have slight color differences that are noticeable after installation. Buy all your boxes at once from the same lot number, which is printed on the box.
Do I need to buy extra flooring to keep for repairs?
Yes, keep 2 to 3 extra planks or tiles after the job. If a board gets damaged in 5 years and the product is discontinued, you will be glad you kept some. Tell your customer to keep them too.
