How to Cut Tennis Balls for Chair Legs

Many schools place tennis balls on chair legs because they act as simple floor protectors that reduce classroom noise and help chairs glide smoothly across floors. If you want to make them yourself, this guide explains how to safely cut tennis balls so they can fit onto school chairs and desks.

Cut tennis balls are commonly used in classrooms, libraries, and other learning environments because they help reduce scraping sounds when chairs move. They can also help protect tile, wood, and vinyl floors from damage caused by metal chair legs.

Why Schools Put Tennis Balls on Chair Legs

Teachers and school maintenance teams often use tennis balls on chairs for several reasons:

• Reduce loud scraping sounds in classrooms
• Protect expensive floors from scratches
• Help chairs slide more smoothly
• Create a quieter learning environment for students

While many schools cut their own tennis balls, others choose to purchase pre-cut tennis balls that are ready to install.

Tools Needed

• Standard tennis ball
• Sharp utility knife or box cutter
• PVC pipe fitting (2¼" to 2½" opening)
• Cut-resistant gloves
• Non-slip work surface

Safety Tips

• Always wear gloves when cutting tennis balls.
• Use a sharp blade so you do not need excessive pressure.
• Cut on a stable work surface.
• Keep your hands clear of the cutting path.

Step-by-Step Instructions

Step 1: Position the Logo

Place the tennis ball with the logo facing downward. When installed on the chair, the logo will be hidden underneath the chair leg.

Step 2: Insert the Ball into the PVC Fitting

Insert the tennis ball into the PVC pipe fitting. The PVC holds the ball steady and helps prevent it from rolling while you cut it.

Step 3: Cut an X Shape

Using a sharp utility knife, cut an “X” shape across the top of the ball. Each cut should be approximately 1½ inches long. This creates four flaps that allow the tennis ball to stretch and fit over the chair leg.

Common Mistakes When Cutting Tennis Balls

• Using a dull knife, which makes the job harder
• Cutting too small of an opening
• Not stabilizing the ball while cutting
• Trying to cut too many balls at once

Because cutting tennis balls takes time, many schools eventually switch to buying ready-to-install cut tennis balls instead.

Pre-Cut Tennis Balls vs DIY Cutting

If you need a large quantity for a school or facility, purchasing pre-cut tennis balls can save time and reduce labor.
