How To Measure A Treadmill Belt

How to Measure a Treadmill Belt (On or Off the Machine) + Where to Buy a Custom Replacement

Whether your treadmill belt has stretched, torn, or simply worn out, getting the right replacement starts with accurate measurements. But don’t worry—measuring a treadmill belt is easier than it sounds, and you can do it with just a few basic tools.

In this guide, we’ll walk you through how to measure your treadmill belt both while it’s still on the treadmill and after it's been removed, plus show you the best place to order a custom-sized treadmill belt online: TreadmillReplacementBelts.com.

🧰 What You'll Need

• A flexible measuring tape

• A marker or chalk (optional)

• A notepad or phone to record dimensions

• Access to both sides of the treadmill

✅ Method 1: Measuring the Treadmill Belt While Still On the Treadmill

If the belt is intact and still wrapped around the rollers, follow these steps:

1. Measure the Width

   • Use a measuring tape to measure the width of the belt from edge to edge.

   • Measure in inches or centimeters—just be consistent.

2. Mark the Belt Start Point

   • Use a piece of tape, chalk, or a marker to mark a starting point on the belt.

3. Roll and Measure the Length

   • Slowly rotate the belt by hand (or have someone help) while you measure the full loop from your starting point back to the start.  You can also measure in sections as you go along and add them together when you're done.

   • This gives you the total belt length.

   • If the belt is stretched it is recommended to reduce a bit off the overall length measured to compensate.  The amount depends on how much it's stretched.  This can be judged by looking at how much wiggle room there is at the rollers. 

✅ Method 2: Measuring the Treadmill Belt Off the Treadmill

If you’ve already removed the belt, this method is even easier:

1. Lay the Belt Flat

   • Place the belt on a clean, flat surface.

2. Measure the Width

   • Simply measure from one side of the belt to the other.

3. Measure the Length

   • Run the measuring tape along the entire outer edge of the belt.
