How To Measure for New Flooring

January 6, 2023

If you are looking for ways to give your home a facelift without a full remodel, new flooring can be a great option. New flooring can transform the look and even the functionality of a space. In addition to these great benefits, new flooring can also increase your home’s value as well.

The first step in a new flooring project is to determine how much flooring you will need. You will need accurate calculations to ensure that you purchase the right amount of flooring for your space.

This quick guide will help you understand how to find square footage of a room for flooring purposes.

Tools You Will Need

To get started, you should assemble the tools you will need for accurate measurements. The following items will be needed.

  • Tape measure
  • Paper
  • Pen/pencil
  • Calculator


It is sometimes necessary to establish a rough estimate. This can be the case when a room is not perfectly square or rectangular. When estimating, you should start with the biggest measurements and work from there, subtracting from your total the floor areas that will not need new flooring.

To come up with a rough estimate, you will calculate the gross square footage of the room. It would help if you began with the longest measurement from wall to wall in all directions. Then you can subtract for permanent objects such as pillars or islands, and for any irregularities in the room.

Gross area can be found by multiplying the length by the width. You should calculate each room individually.

Subtract Unfloored Areas

You are now ready to subtract the areas that will not need flooring. This will include permanent objects in the room, such as pillars or islands.

Get a Grand Total

If you are flooring more than one room, then you will want to get a grand total of the square footage of all rooms combined for purchasing materials.

You can accomplish this by simply adding together the square footage of each room individually. It is important to remember that the square footage of a room should be done individually and then added together at the end.

Consider Waste

One of the most challenging aspects of measuring flooring is considering how much waste will be included in the number. Flooring installation will require several cuts to the flooring material. This will create some waste material. This must also be factored in when you are calculating square feet for flooring you need to buy.

The rule is that you should add 10% to the total amount you calculated to make up for waste. This is a bugger to ensure that when the flooring materials are cut, there will still be enough flooring to cover the space even if some mistakes are made.

Consult a Professional

Flooring installation may not be a DIY project for everyone. If you feel unsure about how to measure flooring or how to properly install flooring, you should reach out to a flooring professional in your area.

They will be able to help you make great flooring decisions and complete the project professionally.
