To work out how much flooring you need, multiply each room's length by its width, add the rooms together, then add extra for cuts: about 10% for a straight lay, 15% for diagonal and 20% for herringbone or chevron. Divide the total by the square feet printed on one box and round up. A 12 × 14 ft bedroom is 168 sq ft, so with 10% extra you buy about 185 sq ft.
Five Measuring Mistakes That Leave You Short
1 Measuring wall to wall, not into doorways
Flooring runs under door jambs and into closets. Measure into each doorway and closet, or add them as their own small room.
2 Forgetting extra for cuts
Every row ends in a cut. Diagonal and herringbone layouts mean far more cuts and more waste, which is why the calculator adds more for them.
3 Buying from different batches
Order everything at once and keep a little spare from the same production run for future repairs, because color varies between batches.
4 Rounding down the boxes
Always round up to the next full box. Running one box short in the middle of an install stops the job.
5 Skipping the stairs and odd shapes
Stairs are measured per step, not by area, and L-shaped rooms are easiest split into two rectangles. Add each piece as its own room.
