How Much Flooring Do I Need? A Simple Measuring Guide

Ordering the right amount the first time keeps your project on schedule and your floor matched. Here is the simple method installers use.

1. Measure each room

Measure the length and width of each room in feet, wall to wall, and multiply them to get square feet. For L-shaped or irregular rooms, split the space into rectangles, measure each one, and add them together. Include closets and any area under appliances that will get flooring.

2. Add extra for cuts and waste

Every installation loses some material to cuts at walls, doorways and the ends of rows. Add 10% for a standard straight layout. Add 15% or more for diagonal installs, herringbone, or rooms with many angles.

3. Round up to whole boxes

Flooring is sold by the box, and each floor lists the square feet per box. Divide your total (with waste) by the square feet per box and always round up.

Step Example
Room size 12 ft x 15 ft = 180 sq ft
Add 10% waste 180 x 1.10 = 198 sq ft
Square feet per box 20 sq ft
Boxes to order 198 / 20 = 9.9, round up to 10 boxes

4. Order everything together

  • One order, one production lot. Ordering all of your flooring at once helps keep color and grain consistent from box to box.
  • Keep a spare box. It makes future repairs simple and invisible.
  • Remember trim. Stair nose, transitions, baseboard and underlayment are easy to forget. Add them to the same order so everything arrives together.
