How to Measure Furniture Dimensions

Whether you’re buying new furniture or moving an old one, your home aspects like ceilings, doorways, and stairways play a massive role in where you finally place the piece. If you have the measurements on hand, you will instantly know where something will go.

Step #1: Assemble the Required Materials

  • A measuring tape
  • A notebook
  • A pencil and eraser
  • Graph paper
  • A newspaper
  • A scale
  • A protector

Step #2: Know the Basics 

To take a precise and accurate reading, first know the basics of measurement. So, these are three basic terms you need to know.

  • Length: In the context of measuring pieces of furniture, length is the longest side. It is the horizontal distance between two far opposite arms of the furniture.
  • Breadth: Breadth is also a horizontal distance between the two closest arms. However, this dimension is shorter than length, and you can also term it as width.
  • Height: The height of a piece of furniture is the distance between its topmost point and the floor. This dimension is mutually perpendicular to the above two and lies on the z-axis.

Step #3: Measure the Length

After knowing the fundamentals of dimensions, take your measuring tape to proceed. Also, take a notebook, pencil, and an eraser to note the readings and erase errors.

  1. To measure the length of your furniture, put the tape’s hook at any end and extend.
  2. Note the distance between the two farthest sides on your record book.
  3. If the hook falls off, remove the furniture cover to get a sharp edge so that you can hook in.
  4. Ensure that the line joining the two points remains parallel to the floor.
  5. You can also use a protector to ensure that the tape is straight and parallel.
  6. Pull the tape tightly so that there isn’t any slack on the tape.
  7. Take the value of two more corresponding points and find their average.

Step #3: Measure the Breadth

To measure the breadth of your furniture, hook your measuring tape in any of the corners. Now, extend the measuring tape towards the closest side from the hooked point.

Keep the hook of the measuring tape firmly attached at the point. Just like you have measured for height, ensure that the measuring tape remains parallel to the floor.

Keep in mind that the strip should be free from slack, and it must not twist. Use a scale/ruler to determine the exact value from the measuring tape. Keep the ruler on edge and note the value at which it intersects with the tape.

Take another set of reading on the opposite side and evaluate the average.

Step #4: Measure the Height

Calculating the height differs from the above steps, as you have to work along the z-axis.

  1. Start by attaching the end of your measuring tape to the floor with your toes.
  2. Be careful in attaching the end so the clamp rests flat and the initial scale just stands.
  3. Taking the reading from the seat’s end will be messy and the process confusing.
  4. Besides, you’ll need a ruler longer than your seat width to intersect it with your tape. Therefore, take the reading from the back of your furniture.
  5. If the back of your furniture is flat, you can quickly scale with your tape by resting on it.
  6. Take three readings on the back and its adjacent corners. Take out the mean of the three readings and note them down. 

Step #5: Measure the Furniture Diagonals

Every piece of furniture has two pairs of diagonals, such as recliners and sectionals, which you need to measure. So, start by measuring the longer diagonals present at the back.

Grab your measuring tape and hook the clamp on any corner of your furniture. Extend the tape till it reaches the diagonal corner.

Pull the tape firmly so that it does not get slacked and twisted. Be precise in hooking the clamp on the corner to avoid the least counts.

Make sure that the measuring tape makes an angle of 45° with the furniture’s bottom-line. Use a protector to ensure that the angle made doesn’t exceed or recede 45°. 

Use two corresponding diagonal points and take out their mean value. Repeat the same procedure to measure the diagonals of the two arm sides.

Key Points To Remember

  • To get accurate readings, always know the reliability and accuracy of the tape. It is because every inch matters when you relocate your furniture.
  • Stretch the measuring tape so that there isn’t any slack in it. If the tape is made of fabric, make sure it doesn’t get twisted.
  • Always take a minimum of 3 readings to calculate the mean value. It is because your furniture may not be even from all sides.
  • Always use a protector to check the angle made by the tape with the base. It must be 45° while measuring diagonals and 0° while measuring length and width.


There are many aspects why measuring furniture is necessary. If you are moving to a new place, you have to measure your furniture and your room. This piece of writing will help to measure your furniture dimensions precisely.
