Frequently Asked Questions
How do I calculate how much flooring I need?
Calculate room area, then multiply by 1 plus the waste factor. A 200 sq ft room with 10% waste needs 220 sq ft of flooring.
How much extra flooring should I buy?
Buy 10% extra for straight layouts, 15% for diagonal layouts, and 15-20% for herringbone or chevron. Add another 5% for complex rooms or first-time DIY installation.
How do I calculate flooring for multiple rooms?
Use the Add Room button, name each room, and choose the floor type and pattern for each one. The calculator totals the order quantity and groups it by material type.
How much does it cost to install flooring?
Installation depends on the material. Carpet may run about $1-$2 per square yard, while hardwood can run about $4-$8 per square foot. Use the cost table as a national average, 2025 starting point.
How many boxes of flooring do I need?
Divide your total order quantity, including waste, by the coverage printed on the flooring box. Always round up to a whole box.
Should I buy extra flooring for repairs?
Yes. One extra box per room is a practical reserve for future repairs, especially when color lots, dye lots, or wood grain batches may change.
