How to Calculate the Floor Area for Laminate Flooring

Updated February 21, 2017

Laminate flooring along with almost all other types of flooring is measured in square feet. This means that in order to purchase laminate flooring for a room in your house you will need to know how many square feet that particular room is. Finding the area of your room isn't too difficult if you follow a few easy steps, and once you find your area, you're ready to buy your new flooring.

Calculating the area of a rectangle can be done by multiplying the length of the room by the width, and the area of a square can be calculated by multiplying one side by itself, according to math.com. Because most rooms in a house are rectangles, the same formula can be used to calculate the area of a floor.

Measure the length and width with a tape measure; it's important that you measure in feet and not inches. This is because ultimately we want the area to be determined in square feet because floor manufactures use square feet to measure their products. A box of laminate flooring might have printed on its packaging that it will cover three square feet.

It doesn't matter whether you measure the length or the width first because you will end up with the same answer either way. If perhaps you end up with a width or length measurement that is a certain number of feet plus a few inches, round up to the next foot to make sure you will have enough material. It's OK to have a bit too much material, but you certainly won't be happy if you run out before the job is finished.

Once you've taken your width and length measurements and rounded up if necessary, multiply the two numbers together and your answer will the number of square feet in your room. If by chance you took your measurements in inches, it's still important that you convert to feet.

If your floor is 12 feet by 12 feet, which would be a square, multiply 12 by itself for an area of 144 square feet. If your floor is 12 feet wide and 15 feet long, multiply 12 by 15 for an area of 180 square feet.

Tip

Measuring a room that isn't a rectangle can be done by sectioning off the room into smaller rectangles. If your room has an island, cutaway, landing or other elements, like many houses do, finding your area isn't any more difficult, it just takes a little more measuring. Before you start measuring your room, section it off with painter's tape in as few rectangles or squares as possible. If you have an island in your kitchen, tape off the floor surrounding the island in rectangular sections. Once you have your entire room taped off, find the area of each section and add all the sections together to find the area of the room.

Warning

Any time you're attempting a home-improvement task it's a good idea to measure everything twice to save you from a headache down the road.
