How Long Should A Treadmill Be For Running

When it comes to running on a treadmill, one of the most important considerations is the length of the treadmill deck. The length of the treadmill deck determines how much space you have to stride and run comfortably. As a passionate runner and fitness enthusiast, I have spent countless hours researching and trying out different treadmill models to find the optimal length for running. In this article, I will share my insights and provide you with all the information you need to determine how long a treadmill should be for running.

The Importance of Treadmill Length

The length of a treadmill is crucial for several reasons. Firstly, it determines how natural and comfortable your running stride will be. A treadmill with a deck that is too short can restrict your stride, causing you to take shorter steps. This can negatively impact your running form and may lead to joint discomfort or even injuries over time. On the other hand, a treadmill with a longer deck allows for a more natural running stride, enabling you to extend your legs fully and maintain proper form.

Secondly, the length of the treadmill deck also affects the overall stability and safety of your running experience. A longer deck provides a more stable surface, reducing the risk of tripping or losing balance while running at higher speeds. It gives you the confidence to push your limits and focus on your training goals without constantly worrying about your foot landing off the edge.

Recommended Treadmill Length for Running

Based on my personal experience and extensive research, the recommended minimum length for a treadmill deck for running is 55 inches (140 cm). This length allows for a comfortable running stride for most individuals, including those with longer legs. However, if you are tall or have a longer stride, I would highly recommend opting for a treadmill with a longer deck, preferably around 60 inches (152 cm) or more. This will ensure that you have enough space to fully extend your legs and maintain proper running mechanics.

It is worth noting that while longer treadmill decks provide more room for running, they also require more space in your home or gym. Make sure to measure the available space and take into account the dimensions of the treadmill before making a purchase. You don’t want to end up with a treadmill that doesn’t fit comfortably in your designated area.

Tips for Choosing the Right Treadmill Length

When selecting a treadmill for running, here are a few additional tips to consider:

  1. Take your height and running stride into account. If you are tall or have a longer stride, opt for a treadmill with a longer deck.
  2. If possible, try out different treadmill models at a local gym or fitness store to get a feel for the deck length that suits you best.
  3. Consider the type of running you will be doing. If you are mainly going to use the treadmill for walking or jogging, a shorter deck may be sufficient. However, if you plan on running at higher speeds or training for longer distances, a longer deck is recommended.
  4. Read reviews and research the specific treadmill model you are interested in to ensure it provides a comfortable and spacious running surface.


The length of a treadmill deck plays a vital role in ensuring a comfortable and safe running experience. While the recommended minimum length for running is 55 inches, it is crucial to take into account your height, stride length, and training goals when choosing a treadmill. Remember, investing in a treadmill with the appropriate deck length will not only enhance your running performance but also minimize the risk of injuries. So, take your time, do your research, and select a treadmill that suits your needs perfectly. Happy running!
