How to Identify the Right Treadmill Belt Size
If your treadmill belt is slipping, worn out, or cracked, it might be time for a replacement. But before you order a new one, it’s important to know the exact size you need. Ordering the wrong belt can lead to poor performance—or worse, damage to your treadmill.
At 306 Fitness Repair & Sales, we make it easy to find the right treadmill belt size for your machine. Here’s how to do it:
1️⃣ Check the Model Number First
Your treadmill’s model number is the key to finding the right belt.
- Look for a sticker or metal plate near the power cord, under the frame, or along the motor cover.
- Write down the brand, model name, and serial number.
You can then use this info to match your belt by using the search function at 306fitness.com or request a parts quote for your specific model.
2️⃣ Measure the Old Belt (If the Label Is Missing)
If you can’t locate the model information, you can measure your old belt instead.
- Unplug the treadmill and remove the safety key.
- Measure the length by running a soft measuring tape around the full loop of the belt. You can also use a piece of string if you do not have a soft measuring tape.
- Measure the width of the belt at its widest point.
- Write down both measurements in inches or millimeters.
Example: 19” wide × 120” long
Even small variations (½ inch) can affect fit, so accurate measurement matters.
3️⃣ Check the Belt Type
Treadmill belts aren’t all the same. Identify what kind you need:
- Standard walking belt – lighter and thinner for casual use
- Running belt – thicker and more durable for higher speeds
- Commercial belt – built for heavy-duty use in gyms
