Treadmill Dimensions List: Width, Length and Height

A treadmill is a pretty big piece of equipment. But how big are they exactly and what sizes are available out there? Here’s what you want to know.

The average size of a home treadmill is; 33.9” (w) x 75” (l) x 57.9” (h). Although some are as wide as 40″ and 85″ long while others are smaller. Belt length and width are the main deciding factor for overall treadmill dimensions. To use the treadmill, at least 2″ free on all sides is necessary.

If you want to know why that is and where the numbers came from, keep reading below.

Just throwing some numbers out there might help you but it’s also good to see where the numbers come from to see what the options are and what to expect from a treadmill.

Here’s a chart with many popular models of home treadmills and their dimensions.

  • The average size of a home treadmill is; 33.9” (w) x 75” (l) x 57.9” (h)
  • Home treadmill widths range from 25” to 40” although the majority of models has a width of 32” to 36”.
  • Treadmill lengths range from 57” to 85” but the majority of models falls into the 70” to 80” range.

While getting a treadmill that fits in your space is important, it’s not the only factor when choosing one. You can find a complete guide of what to look for by clicking here.

Belt Size vs. Treadmill Size

You might wonder why there is such a big difference in treadmill sizes, especially the length can vary widely. The biggest reason for that is the belt size. The belt is the spinning part you actually walk on. They come in different sizes which makes up the bulk of the difference.

The most common size for treadmill belts is 20” x 60”. As you can see from the chart above, many models for home gyms are that size. However, there are also quite a few that deviate from that size. Of course if you have a larger/smaller belt, the whole machine will be larger or smaller.

There are also some differences in packaging between models that can make a certain belt size treadmill smaller/larger but in general, the treadmill scales with the belt.

The belt size is important because it impacts what you can do on it. Short belts aren’t well suited for running while narrow belts might not fit your size.


Don’t Buy a Small Treadmill Because It Fits

You might be tempted to buy a compact treadmill because it fits in your space. However, it’s very important to think about what you want to do with your treadmill and how big you are.

Not all treadmills have the same size.

As said above, small treadmills tend to have smaller belts. Smaller can mean shorter as well as narrower.

By far, most treadmill belts are 20” wide. A few are narrower and a few are wider. 20” is the most popular width because it just works to run on for the vast majority of people in the population. If you are anywhere near a normal size, a 20” wide belt is fine.

For normal sized people as little as 16” wide is OK for just walking although 18” is better. For running 20” is much better.

The length of a treadmill belt is even more important. It dictates what you can do with your treadmill but it’s also dependent on your height. Let me explain;

When you run you move your feet further in one step then when walking. That means you need a longer belt to run on than to walk on otherwise your foot could land outside the belt and that’s not going to be fun. Sprinting needs more length than jogging which in turn needs more length than walking.

Suggested: What’s the top speed of a treadmill?

How much treadmill belt length do you need exactly? That depends on your height. (Or more specifically, the length of your legs but height is a good proxy). The taller you are, the more belt length you need because your feet will land further apart.

In the following links you can find the average stride length for walking.

Stride length by height (walking)

Those are the stride lengths for walking, but that doesn’t mean that’s the size belt you need. You’ll want at least 10” extra belt length on top of your stride length. However, even the tallest person can walk on the shortest treadmill in the list above.

For running, things change quite a bit. Olympic sprinters have stride ratio (height to stride length) of 1.14 to 1.35. Those are Olympic level sprinters though. During sprinting, you take longer strides than while jogging/running. Also, Olympic athletes are a bit different from us normal people.

A good rule of thumb is multiplying your height in inches by 0.8 to get an approximation of the needed belt size to run on.

That means you have to think about; how tall you are (or any other users) and if you want to run or just walk on your treadmill. That’s why choosing a treadmill just on size is not a good idea. However, once you picked a belt size, you can choose the smallest treadmill within that category.

Favorite Cardio Machine Accessories

Check out these accessories that improve a home cardio workout:

  • Equipment mat: All cardio equipment should be put on an equipment mat. The Rubber-Cal mat (Amazon) is an affordable yet very high quality choice.
  • Tablet holder: Cardio can be boring. With this tablet holder (Amazon) you can follow along with on-demand workouts or just watch a movie on any cardio machine.
  • Heart rate monitor: Monitoring your heart rate is very important while doing cardio. The Polar H10 (Amazon) connects to almost anything you can imagine and is very accurate.
