How to Measure & Determine a Chair Mat Size & Pattern?

to measure and determine chair mat size and pattern

Are you finding it difficult to move around your office space on a rolling chair? It sure can be a pain navigating from one end of your desk to another on a screechy rolling chair when you’re trying to multitask or collaborate with team members.

A chair mat is important to have in your workspace. It is the solution to all of your maneuvering woes and it protects your floors from marks and spills.

Chair mats are designed to keep your floors and carpets protected, and they reduce strain and pressure on your joints. They provide ergonomic support allowing you to easily converse and work alongside your team members.

Pick the right mat based on its thickness and shape. Also consider key factors like the fabric, how well it fits into your space, and how it looks. 

Besides the ergonomic and functional benefits, a great-looking mat can also beautify your ordinary, mundane-looking workspace.

How Are Chair Mats Measured?

Some office spaces can do with a standard chair mat. Other office spaces require custom-fit mats that facilitate easy rolling and protect floors against cracks and damage.

Before you choose a chair mat, you have to verify a few important factors that will help you determine its ideal size.

We’ve explained two of them below.

Thickness of the Chair Mat

The thickness of the mat will depend on the type of flooring. Too thin a mat can crack or wear out easily, so always choose a thicker fabric over a thinner one.

Mats that are exclusively designed for carpets have cleated backs to deter slips. Because of their cleated backs, they should not be placed on hard floors as they can damage the flooring.

The thickness of the mat also depends on how frequently the mat will be used and the load on the chair. The more load on the chair, the thicker the chair mat.

Shape of the Chair Mat

There are multiple mat shapes available. Choose one that matches the configurations of your workspace the closest. The three most common shapes include rectangle, lip, and light bulb.

If your workspace only includes a standard writing table, you should go for a lip or rectangular-shaped mat. For a corner workstation design, an L-shaped or rectangular-shaped chair mat is the ideal choice.

Light bulb mats work well for corner desks and L-shaped desks. Rectangular-shaped chair mats are the most versatile and popular shape of them all.

Now that you are aware of the important factors to consider before purchasing a chair mat, let us look at the simple steps to measure one.

Steps to Measure a Chair Mat

Before you can measure a chair mat, you will need the right tools.

Required Tools

  • Piece of paper

Step 1

Using a measuring tape, measure the corresponding edges and the area that you want to cover with the chair mat.

Step 2

Draw a figure of the chair mat shape you want for your space, and label the length from each side of the mat.

Step 3

If you have a carpeted floor, the last step is to measure its depth using a paperclip.

Straighten a paperclip and push the end through the carpet till it reaches the subflooring. Put your finger on the paperclip, which is on the top edge of the carpet, and place it against the measuring tape.

You now have the measurements to ensure your chair mat fits perfectly in the space you want it to.

If your customized chair mat arrives rolled up, make sure to warm it using a hairdryer. This warming technique helps your chair mat lie flat on the ground.

How to Pick a Chair Mat Pattern and Shape?

Chair Mat Pattern

If you want your beautiful hardwood floor to be visible, a clear vinyl chair mat is a perfect purchase.

You also have the choice between colored and patterned vinyl chair mats. They are usually made of jute or a wood finish.

Go for a mat pattern and color that matches the aesthetic of your workplace. If you want to create the illusion of a bigger space, light-colored mats with faint patterns are a better choice compared to dark-colored mats.

Chair Mat Shape

Rectangle, lipped, and contour-shaped mats are best for traditional-shaped desks. L-shaped mats are ideal for corner and cubicle-styled desks.
