FitScore Duel
Both scores use the weights of our best budget treadmill guide: affordability 35%, performance, durability and comfort 15% each, practicality and features 10% each. Budget buyers want the most treadmill for the money, so affordability counts most, but the machine still has to run well and last. The TLX is not ranked in that guide, so its score uses the same weights. It leads on performance and comfort thanks to its stronger motor and bigger deck, while the TL scores higher on affordability, which keeps the gap to about 2 points.

Key Differences
- The TLX has a 3 HP motor and reaches 12 mph; the TL has a 2.6 HP motor and tops out at 10 mph.
- The TLX climbs to 12% incline; the TL to 10%.
- The TLX has a 20 × 60-inch deck; the TL an 18 × 55-inch deck, which is narrower and shorter.
- The TLX has a 7-inch display; the TL a 5-inch display.
- The TL is smaller and lighter, at about 166 lb against about 221 lb for the TLX.
- Folding, the 300-lb rating, iFIT features and the listed warranty are the same.
Motor, Speed and Incline
The TLX pairs a 3 HP motor with 0–12 mph and 0–12% incline. The TL uses a 2.6 HP motor with 0–10 mph and 0–10% incline, which covers walking, incline walking and easy jogging.
Independent testers found the TLX steady with no wobble at higher speeds and measured about 23.5 seconds to go from 1 to 12 mph. They describe the drive motor as quiet but the incline motor as noisy when it adjusts, and some owners find the incline slow to change.
Winner: ProForm Carbon TLX
Running Deck and Cushioning
The TLX’s 20 × 60-inch deck gives you 2 more inches of width and 5 more inches of length than the TL’s 18 × 55-inch deck. That extra room matters for taller users and anyone who jogs or runs, while the TL’s deck is better suited to walking and light jogging.
Both use ProShox cushioning. Testers who used the TLX for several months found it middle-of-the-road, neither soft nor hard, and one tester felt it differed little from running outdoors, so it is not the best pick for sensitive joints.
Winner: ProForm Carbon TLX
Console, Controls and iFIT
The TLX has a 7-inch LCD and the TL a 5-inch LCD, each with a device shelf. Testers liked the TLX’s large one-touch speed buttons, but they disliked the two-row button layout and noted that a large tablet can hide the display.
Both rely on iFIT for classes, SmartAdjust, ActivePulse heart rate training with a Bluetooth monitor, the AI Coach and syncing with Strava, Garmin and Apple Health, and each needs an iFIT Train membership for these. Testers found the TLX must be unlocked through a connected device even without a membership, with no built-in programs outside iFIT, and owners of the TL report few useful workouts without the app.
Winner: ProForm Carbon TLX
Footprint, Folding and Assembly
The TL needs about 68.6 × 32.1 inches of floor space against about 73.2 × 34.6 inches for the TLX, and it weighs about 55 lb less. Both fold, with a hydraulic system that lowers the deck smoothly.
Testers found the TLX’s assisted fold easy to use despite its weight and put it together alone in about an hour. Amazon buyers say the TL goes together in about 90 minutes.
Winner: ProForm Carbon TL
Build, Durability and Warranty
Owners describe both as sturdy, stable and quiet enough for everyday use. Durability is the main concern for both in owner reviews: several TL owners report a breakdown within the first year, and one TLX owner reports two failures in under a year, while another describes a belt that hesitates below 3.5 mph.
The listed warranty is identical: 10 years on the frame and 1 year on the motor, parts and labor.
Winner: Tie
Who Should Buy Each
Joggers and taller users: Choose the ProForm Carbon TLX for a 20 × 60-inch deck, 12 mph, 12% incline and a 7-inch display.
Walkers with less space: Choose the ProForm Carbon TL for a smaller, lighter folding frame and 10% incline at a more affordable level.
Consider Instead
If you would rather use your own apps than iFIT, look at the Horizon T202, the top pick in our best budget treadmill guide. It folds and has a 20 × 60-inch deck, 12 mph, 12% incline, a 325-lb rating, Bluetooth for streaming workouts from your device and a lifetime frame and motor warranty.
Final Verdict
For most budget buyers, the ProForm Carbon TLX is the better buy: a stronger motor, more speed and incline, a 20 × 60-inch deck and a bigger display, with the same folding design and warranty as the TL. Choose the ProForm Carbon TL if you mainly walk, want a smaller and lighter treadmill and prefer to spend less.
