The T303 and 7.0 AT are two similar treadmills from Horizon Fitness. Find out their differences and what option is the best choice for you.
Some of the main differences between the Horizon T303 and 7.0 AT are that the Horizon T303 is lighter and has a lower deck height.
On the other side, the Horizon 7.0 AT has bigger rollers, a few more incline options, compatibility with certain workout apps, and a slightly more budget-friendly price.
The first thing to mention is that both of these treadmills have a motor power that is suited for individuals with an average weight who want to walk or jog lightly. For more intense workouts, you likely need more motor power.
That being said, if you plan to move your treadmill around a lot or need the lower deck height because of limited mobility, the Horizon T303 could be the right choice.
If these things do not apply to you, you will likely prefer the Horizon 7.0 AT.
This treadmill should last longer and offer more comfortable workouts due to the bigger rollers, has more incline options, has more workout app compatibility, and is more budget-friendly.

Differences Horizon T303 vs 7.0 AT explained in detail
People who are more experienced with treadmill features and know what they want in them may be able to choose between the Horizon T303 and 7.0 AT by looking at the table of differences and the prices.
That being said, you may also still be unsure about what certain features mean, why they should play a role in your decision, and to what extent they should make a difference in your situation.
Rollers
Treadmills are basically moving belts that allow you to walk and run in place. These belts are stretched around rotating cylinders called rollers. Rollers can vary in details like size.
The Horizon T303 has rollers of 46mm/42mm (1.8″/1.65″). The Horizon 7.0 AT has rollers of 60mm/46mm (2.36″/1.8″) which is a nice amount bigger.
A very rough general guideline is that bigger rollers tend to be better (there is a limit of course). The first reason for this is that big rollers tend to cause less wear and tear on the belt and treadmill motor.
Secondly, bigger rollers tend to reduce the risk of the belt slipping, not moving at the same speed as the rollers.
Slipping treadmill belts tend to reduce the quality of your workouts so reducing the risk of this happening is positive.
Something important to note is that your treadmill motor does need to be strong enough to deal with the bigger rollers.
The interaction of the motor power and roller size is not always easy to predict. However, the lack of customer mentions about this implies this is at least alright for both the Horizon T303 and 7.0 AT.
That means that you can expect some of the benefits above from the Horizon 7.0 AT over the Horizon T303.
Winner: Horizon 7.0 AT
Incline options
Many treadmills allow you to change the angle of the deck. More specifically, allow you to raise the front part to get different incline levels.
Both the Horizon T303 and 7.0 AT have this feature too but they vary in terms of to what extent this is possible.
The Horizon T303 can be put in incline levels ranging from 0% to 12%. The Horizon 7.0 AT goes a bit steeper with incline levels ranging from 0% to 15%.
Incline positions can help you burn more calories, engage your muscles in a different ratio, keeps things interesting, and makes certain workout videos feel more immersive.
Whether and how much you value the 3% extra incline from the Horizon 7.0 AT depends on things like your personal preferences and training goals.
Winner: Horizon 7.0 AT
Weight
The weights of the Horizon T303 and 7.0 AT are relatively straightforward details but it may not be clear why this is a relevant feature difference.
First of all, the Horizon T303 weighs 194 pounds (88 kg). The Horizon 7.0 AT is a good amount heavier at 253 pounds (114.8 kg).
There are some situations where people need to know this number in terms of the weight capacity of the floor.
However, the weight difference of the treadmills will mostly be important for people who plan to move their machines around a lot.
The Horizon T303 and Horizon 7.0 AT are both foldable and have transport wheels. A lighter treadmill will require less effort to move around.
How important the difference is to you depends on your strength level and how much you plan to move your treadmill around.
Winner: Horizon T303
Deck height
The deck height is how much distance the walking/running surface is removed from the ground. This is generally not the most important treadmill feature but it does have some consequences.
For example, some people have a relatively low ceiling in their workout room. To come nowhere near close to bumping their heads against the ceiling, some people find low deck heights a nice addition.
Additionally, people with limited mobility may like lower deck heights because it makes treadmill walking sessions easier to access.
The Horizon T303 does relatively well in terms of deck height with a 7.25″ height. The Horizon 7.0 AT is slightly higher with an 8.63″ height.
For most people, this is not a feature that will completely sway their decision one way or the other. However, in some situations, it does make the Horizon T303 look more attractive.
Winner: Horizon T303
Workout programs
Most normal ways of using a treadmill can benefit your health. Even so, certain sequences of intensities and time periods are more effective for this than others.
Additionally, switching up your workouts can simply make your exercise routine more enjoyable.
Both the Horizon T303 and Horizon 7.0 AT come with 6 preset workout programs which include fat burn, hill climb, my first 5K, distance, heart rate, and calories.
The difference between these two treadmills is that the Horizon 7.0 AT can also be connected to certain other workout apps like Zwift.
You can still follow other workout apps while using the Horizon T303 through something like a tablet. However, this treadmill won’t interact with the workout app.
For example, the Horizon 7.0 AT is able to send data about heart rate, speed, incline, distance, and time to Zwift through Bluetooth.
You can still do many interesting workouts on the Horizon T303 but this is a nice addition to the Horizon 7.0 AT if you are a fan of the compatible workout apps.
Winner: Horizon 7.0 AT
Speed and incline quick dial controls
This next difference between the Horizon T303 and 7.0 AT is not that relevant but could be confusing without an extra explanation.
The Horizon 7.0 AT has two extra handles with small wheels that can be used to change the incline and speed of the treadmill.
This would be very useful if there was no other way to quickly change these settings.
However, each treadmill already has quick adjustment buttons so when using the Horizon T303 these changes should be about as easy to make.
Winner: Horizon 7.0 AT but not that important
Price
The Horizon T303 and 7.0 AT each have their advantages and disadvantages in terms of features. However, something to keep in mind is that price matters too when choosing a treadmill.
Exactly how much each treadmill costs depends on where you get them and can change over time. That being said, at the time of writing, the Horizon 7.0 AT is just a bit more budget-friendly than the Horizon T303.
Winner: Horizon 7.0 AT
User reviews
When comparing two treadmills from the same brand like the Horizon T303 and 7.0 AT the features and prices generally give a good idea about what option is the best for your personal situation.
On the other hand, sometimes customer reviews uncover unexpected downsides or trends in quality issues.
At the time of writing, customers tend to be somewhat more positive about the Horizon T303 but this could be because the number of customer reviews is currently lower.
In the case of both treadmills, there are some shipping mistakes, faulty parts, and early wear and tear. This is somewhat common for big cardio machines but unpleasant nonetheless.
That being said, overall, customers are still happy with both the Horizon T303 and Horizon 7.0 AT. The issues mentioned seem to be the exception, not the rule.
Is the Horizon T303 or 7.0 AT right for you?
In short, the Horizon T303 is lighter and has a lower deck height. The Horizon 7.0 AT has bigger rollers, a few more incline options, compatibility with certain workout apps, and a slightly more budget-friendly price.
Something to note first is that the motor power of both treadmills is mostly for walking and light jogging for users with an average weight. For more intense workouts, you will likely need a treadmill with a stronger motor.
With that in mind, the Horizon T303 can be the right choice if you plan to move your treadmill around a lot and or want the lower deck height because of mobility challenges.
That being said, most people will prefer the more budget-friendly Horizon 7.0 AT. Its bigger rollers should last slightly longer and offer more comfortable workouts.
Some people will also find the extra incline options and workout app compatibility important.
