How it is worked out

  1. Floor area is length times width.
  2. The extra percentage is added for cuts, mistakes and pattern matching.
  3. The box count is the area with extra divided by the coverage on the box, rounded up.

Worked example

With the starting values, a room 14 ft by 12 ft is 168 square feet, or 184.8 square feet with 10% extra. At 20 square feet per box that is 10 boxes.
