How to use Flooring Calculator
- Measure the spaceMeasure the length and width of each part of the room. Split an L-shaped room into two rectangles.
- Type each areaType the measurements as you read them, such as 12' 6". Press Add another area for each extra part, and tick Take away for an island or an opening.
- Read the totalThe total shows in square feet, square yards, square metres and acres. Add a waste allowance, a price or the coverage of one box to see what to buy.
Type the rooms as you measured them, in feet and inches, and the coverage printed on one box of laminate, vinyl plank, tile or hardwood. The page starts with 10 percent added for cuts and waste, rounds the boxes up to whole boxes, and gives the cost if you type the price per square foot. Change the waste to 15 percent or more for a diagonal or herringbone layout.
How it works
Flooring Calculator is a web page that does its work on your own device. Everything you type or choose is worked out by your browser and never sent to a server, so nothing is stored and there is nothing to delete. There is no account, no sign-up and no limit on how often you use it.
Before you order
Buy all the boxes from the same production lot so the colour matches, and keep one spare box for repairs. Many installation guides also ask for the boxes to sit in the room for a day or two before laying, so the boards adjust to the room.
