# Measuring a Room

For a square or rectangular room or wall, you will first need to measure the length and then the width of the space. Then multiply the length and width to get the total area of the space. Length x Width = Area. For example, if your room measures 10 feet wide x 5 feet long, your total area will be 50 square feet.

As a general rule, Geon Tile recommends adding in a 15% waste factor for waste, errors or tiles that may be damaged during the installation process. To get your waste-adjusted area, multiply the area calculated 1.15. For example, if your total area is 50 square feet, you will need to order enough tile, thinset and grout for 58 square feet.

If your room is not perfectly square (such as an “L” shape), it is helpful to split up the room into two sections in order to calculate the total area.  Measure the length and width of each rectangle, as above, and calculate the total area of each rectangle. Add all of the areas together to get a total. Don’t forget to add the 15% waste factor – multiply your area by 1.15.

If your room has a diagonal shape or corner, you will need to split up the room into two sections in order to calculate the total area. First, measure the rectangle’s length and width. Then calculate the total area of the rectangle.

Next, measure the triangle’s base width and height (top-to-bottom length). To get the area of the triangle, multiply height by base width and divide the total by two. Base Width  x Height x ½ = Area.

Finally, add the areas of the rectangle and triangle together. Be sure to add the 15% waste factor – multiply your area by 1.15.
