How to Measure Correctly for Flooring

When buying online, you will be responsible for measuring the rooms where you want to install flooring to determine the amount of flooring material to buy. It is very important to measure correctly, so that you will not have a shortage of material when you go to install your flooring. You also wouldn’t want to order more flooring material than you need either, leading to unnecessary costs. For your convenience, has provided a square foot calculator that you may find helpful in tabulating the square footage of flooring that you will need for your project.   


To avoid any problems, please read the following simple recommendations that will assist you in learning how to properly measure for your flooring, so that you buy only what you need. 


  • To begin, you will need a tape measure, calculator, pen and paper. Make a list of the rooms where you are going to install flooring.
  • Measure the length of your room, round up the nearest foot. For example, if your room is 10 ft. 5 in long, round up to 11 feet. Write down your measurement.
  • Next, measure the width of your room and round up to the nearest foot. Write down your measurement.
  • To get a rough estimate of the amount of square footage of flooring that you will need for that room, multiply the length of the room by the width of the room. For example, if your room is 20 ft. long by 15 ft. wide, multiply 20 x 15 = 300 square feet.
  • If there are any objects in the room that cannot be moved, for example, a kitchen island that won’t have flooring under it, measure the object’s length and width to determine the square footage and subtract that amount from the total square footage for that room. For example, if the object measures 6 ft. long by 5 ft. wide, multiply 6 x 5 = 30 square feet. So, you will subtract 30 sq. ft from 300 sq. ft. – 300 - 30 = 270 square feet.
  • After you do this for each room, then add all of the total square feet for each room together to get your overall total of square footage. 
  • Finally, you must add additional square footage for waste. If you are installing the flooring yourself, you should allow additional 10% in square footage of flooring to allow for cuts and damaged pieces during installation. Multiply your total square footage for your flooring project by 10%. For example, 270 x 10% = 27 square feet. Add this amount to your previous total to get the square footage of flooring that you need to order. Ex. - 270 + 27 = 297 square feet. This will get you the final total of square footage that you need to order to complete your entire project.



How to Measure for Extra Flooring in Irregular Shaped Areas



If you have a bay window or any irregular shaped area that is outside of the square shape of the room, you must allow for additional flooring to cover that area. The following are some guidelines to assist you in determining how much additional flooring to purchase for a bay window or any other irregular shaped areas.


  • First, measure the length of the opening going into the bay window or irregular space. Then measure the width of the narrowest part of the bay window or irregular space. Add the two measurements together and divide the total by two. For example, if the opening of the bay window is 8 ft and the narrowest part of the bay window is 4 ft.  8 + 4 = 12 feet divided by 2. 12 / 2 = 6. 
  • Measure how deep the bay window is by measuring from the window to the opening where the bay window begins. Multiply the depth of the bay window by the total previously calculated. If the depth of the bay window is 5 ft., then you multiply the two totals, 6 x 5 = 30 square feet. So, you will need an additional 30 square feet of flooring to cover the floor inside of the bay window. 
  • Then, you will add your bay window or other irregular shaped area measurement to your total room measurement before you calculate for waste. 270 + 30 = 300 sq. ft. 
  • Finally, add the 10% for waste. Ex. - 300 x 10% = 30 sq. ft. Add 300 sq. ft. (room total) plus 30 sq. ft. (waste) for a final total of 330 square feet needed to complete your flooring project. 300 + 30 = 330 square feet.
