Find how many boxes of flooring to buy for any room, with a cutting-waste allowance so you finish the last row without a second trip.
We take the room area, add a waste percentage for cuts and mistakes, then divide by the coverage printed on each box and round up.
Ten percent waste is the industry default for a straight lay in a rectangular room. Diagonal patterns, herringbone and rooms with lots of jogs and closets run 15% or more. Keep one spare box sealed for future repairs.
Use 10% for a standard straight-lay in a simple rectangular room. Go to 15% for diagonal or herringbone layouts, or rooms with lots of corners, closets and doorways where offcuts can\u2019t be reused.
Yes — keep one sealed box beyond what the calculator says. Dye lots change between production runs, so a matching board for a future repair is much easier to have on hand than to source later.
A lot. Coverage varies from about 18 to 24 sq ft per carton depending on plank size and brand. Always read it off the actual product you\u2019re buying rather than assuming.
Split it into rectangles, calculate each area, and add them together before entering the total. Then keep the waste factor on the higher end because more corners mean more cuts.
The Home Renovation Project Manager rolls every calculator into one budget — room by room, with a shopping list, contractor quote comparison and a live over-budget warning.
