Common Questions
Coverage Calculator FAQ
How much waste should I add?+
Plan about 10 percent waste for a straight lay, 15 percent for diagonal, and 20 percent for complex or herringbone layouts. Set the waste factor in the calculator to match your pattern.
Where do I find coverage per box?+
Coverage is listed on each product spec as square feet per box, and the product page calculator fills it in for you automatically. That lets you size the order without doing the math by hand.
Should I round up boxes?+
Always round up to the next full box. Keeping a spare box on hand helps with future repairs and dye-lot matching.
Can I calculate from room dimensions?+
Yes, use the room-dimensions helper to turn length and width into square footage. From there the calculator estimates the boxes you need.
