The most common method of calculating the square feet of a room is with a measuring tape. For any square or rectangular room, you can use a 25-foot tape and a fastener — since most rooms are under 25 feet long or wide. 

Though these are not ideal for single operators, you can latch the front end of the tape to a stable ledge on one side of the room and slowly pull it back until it has reached the other side. 

However, an inherent flaw in tape measures to calculate the length and width of the room is their tendency to bow and bend when stretched across long distances. This can result in the occasional fluctuations of correct measurements.

6. Binder measurement

Yes, you read right. Even a handy ring binder can help you figure out the measurements of a room! Carefully count how many binder lengths it takes to get from one side of the room to the other. Generally, a one-inch, three-ring binder measures 11.5” in length. Keeping this fact in mind, you should be able to estimate the room’s measurement.

Once you find the technique that fits your needs, simply measure both the length and width of your room. Just remember to create a line perpendicular to the walls on either end. Since most rooms are either square or rectangular, making a line parallel to the adjacent wall works just as well.

How to Measure Walls for Paint or Wallpaper

To accurately measure a room for wall coverings we will use the length of the wall, and the height to the ceiling. The formula will be similar to before.

Step One: Take Measurements

Start by measuring the length of the wall and the height of the ceiling using a tape measure. If you have multiple walls, then do this for each wall surface.

Step Two: Calculate the Area of Each Wall

Next, use a calculator to multiply the length and height, just like before. If, for example, the wall measures 12 feet long and 8 feet high, use the calculator to figure 12 feet × 8 feet and see that the wall is 96 square feet.

Step Three: Add the Wall Areas Together

Repeat this process for each segment of wall in a room to accurately measure a room for any type of wall-coverings. Add the areas of each wall together to get the total square footage of all the walls.

Step Four: Subtract Doors and Window Openings

When measuring for some materials such as paint it might be important to subtract surfaces that will not be covered like doors or windows. Note that when measuring for some material accounting for doors and windows may not be necessary and this step can be skipped.

As you make your way around your room, measuring the square footage of each segment, make sure that you note any doors and windows. Measure the length and width of each one, then multiply to find the area. Finally, subtract each door and window area from the total.

One quick tip: our wallpaper and paint calculators can help estimate wall covering materials after you’ve measured your walls and simplify this whole process, so it might be worth checking them out.

Measuring your room

It would help us if you could measure in millimetres. Always try to be as precise as possible with your measurements, but don’t worry we will call out and double check before anything goes ahead.

  1. Draw an outline of the room, including any doors, windows or breaks in the walls.
  2. Starting in one corner, work your way around the room measuring the full length of each wall.
  3. Take measurements of the walls between openings, doors, windows and pillars etc.
  4. For windows and hatches, measure the height off the ground and the height of the window.
  5. Measure the floor to ceiling height.
  6. Make a note of where any stop taps, gas or electric metres and water outlets are.
