Choosing a treadmill for a heavier person involves more than checking the maximum weight capacity. The running area, stability, speed and folding design all matter, especially if you want a treadmill that supports regular workouts without taking up too much space at home.
In this guide, we compare five foldable treadmills available in the UK, including the WalkingPad X218 and G5i, alongside models from DeerRun, UREVO and MERACH. With weight capacities ranging from 136 kg to 181 kg, we'll help you find the right balance of support, workout performance and space-saving design.
Key Takeaways
- Maximum user weight is a ceiling, not a target. If you weigh close to a machine's stated limit, buy the higher-rated model rather than the one that technically passes.
- WalkingPad's X218 and G5i are both rated to 136 kg (300 lb).
- Running area is another important factor to consider. The WalkingPad X218 has the longest belt in this comparison at 1,400 mm, giving you more room for longer strides when running.
- All five treadmills feature folding designs, with folded thicknesses ranging from 155 mm to 295 mm. Consider the full folded dimensions to make sure your chosen model fits your available storage space.

What "Maximum User Weight" Actually Means
A stated limit tells you the heaviest person the manufacturer will support under normal use. It is not a comfort rating, and it is not a target to work up to. When choosing a treadmill, make sure its maximum weight capacity is suitable for your body weight. If your weight is close to the stated limit, consider a model with a higher capacity. It's also worth comparing the running area, frame design and other features to find a treadmill that suits your workout needs.
WalkingPad X218 — Best for Running Under 136kg

The WalkingPad X218 Foldable Treadmill has the longest belt in this group at 1,400 mm, which is what makes it the running option here rather than a walking-only machine.
Key specs
- Maximum user weight: 136 kg (300 lb)
- Running area: 1,400 × 510 mm (55.1″ × 20″)
- Speed range: 1–18 km/h (1–11.5 mph)
- Motor: 5.25 HP brushless
- Folded size: 1,080 × 840 × 295 mm (42.5″ × 33″ × 11.6″)
- Unfolded size: 1,620 × 840 × 1,080 mm (63.7″ × 33″ × 42.5″)
- Net weight: 58.5 kg (129 lb)
- Controls: KS Fit app and SpeedDial knob
The X218 arrives fully assembled, so you can start using it without a complicated setup. Its foldable design also makes it easier to store between workouts, making it a practical choice for homes where space is limited.
Choose it if you weigh under 136 kg and want a foldable treadmill with a spacious running area for regular running workouts.
WalkingPad G5i — Best Incline Option Within the 136 kg Limit

The differentiator about WalkingPad G5i Foldable Treadmill is an 18% electric incline across 25 levels, which raises the effort of a session without raising the speed.
Key specs
- Maximum user weight: 136 kg (300 lb)
- Running area: 1,300 × 500 mm (51.2″ × 19.7″)
- Speed range: 1–16 km/h (1–10 mph)
- Incline: 18% across 25 levels
- Motor: 1.5 CHP continuous / 4.5 HP peak brushless
- Folded size: 1,160 × 848 × 258 mm (45.7″ × 33.4″ × 10.2″)
- Unfolded size: 1,642 × 848 × 1,107 mm (64.6″ × 33.4″ × 43.4″)
- Net weight: 68 kg (150 lb)
- Controls: KS Fit app and SpeedDial knob
With a 1,300 × 500 mm running area and speeds of up to 16 km/h, the G5i supports walking, jogging and running. Its 18% powered incline across 25 levels also provides more flexibility for different workout intensities. For more options with a maximum weight capacity of 136 kg, explore our 300 lb WalkingPad and Treadmill Collection.
Choose it if you want a foldable treadmill that combines running performance with adjustable incline training.
DeerRun X20 — Highest Stated Limit That Still Folds Flat

The X20 states 181 kg (400 lb), the highest limit in this group, and still folds flat — which makes it the direct answer for a reader who needs more headroom than 136 kg without giving up foldability.
Key specs
- Maximum user weight: 181 kg (400 lb)
- Running area: 1,300 × 450 mm (51.2″ × 17.7″)
- Speed range: 1–18 km/h
- Incline: 15% auto
- Folded size: 1,370 × 773 × 186 mm (53.9″ × 30.4″ × 7.3″)
- Unfolded size: 1,370 × 773 × 1,088 mm (53.9″ × 30.4″ × 42.8″)
- Net weight: 38.8 kg (85.5 lb)
The DeerRun X20 offers a higher weight capacity of 181 kg, although its 1,300 × 450 mm running area is smaller than the WalkingPad X218's 1,400 × 510 mm. While the X20 features a foldable design, its running deck does not fold in half like the WalkingPad X218 and G5i. This is an important difference to consider when comparing storage options for smaller homes.
Choose it if you need a higher weight capacity and have sufficient space for its folded dimensions.
UREVO FoldiMix 5L — Lowest Cost, Walking Pace Only

At £499.99, the UREVO FoldiMix 5L is the most affordable option in this comparison, with a maximum weight capacity of 181 kg. It supports speeds of up to 12 km/h for walking, jogging and running. However, its 1,000 × 400 mm running area is the smallest in this group, which may feel restrictive for taller runners or those with longer strides.
Key specs
- Maximum user weight: 181 kg (400 lb)
- Running area: 1,000 × 400 mm (39.4″ × 15.8″)
- Speed range: 1–12 km/h (0.6–7.6 mph)
- Incline: 9% auto across 9 levels
- Motor: 3.0 HP
- Folded size: 1,330 × 625 × 155 mm (52.4″ × 24.6″ × 6.1″)
- Unfolded size: 1,320 × 625 × 1,110 mm (52″ × 24.6″ × 43.7″)
The UREVO FoldiMix 5L has a stated maximum weight capacity of 181 kg. However, the manufacturer's testing information indicates that its maximum-speed test was conducted at 136 kg. If you plan to use the treadmill for running, it's worth checking the manufacturer's guidance on weight capacity at higher speeds before purchasing.
Choose it if you're looking for an affordable foldable treadmill with a high stated weight capacity, particularly for walking and light jogging.
MERACH T31B1 — Mid-Price with the Steepest Auto Incline Here

The MERACH T31B1 supports a maximum user weight of 159 kg and features an 18% powered incline, the same maximum incline as the WalkingPad G5i. It also offers a 1,200 × 460 mm running area for walking, jogging and running.
Key specs
- Maximum user weight: 159 kg (350 lb)
- Running area: 1,200 × 460 mm (47.2″ × 18.1″)
- Speed range: 1–14 km/h (0.6–8.7 mph)
- Incline: 18% auto
- Motor: 3.5 HP
- Folding: 30-second hydraulic fold
The MERACH T31B1 features a hydraulic folding mechanism for easier storage between workouts. However, its folded dimensions are not specified, so it's worth confirming the storage requirements before purchasing, especially if space is limited.
Choose it if you want a treadmill with a higher weight capacity, adjustable incline and a foldable design at a more affordable price.
Belt Length and Width Matter as Much as the Weight Rating
A treadmill can be rated well above your weight and still feel wrong underfoot. The running area is the number that decides it.
Longer belts suit higher speeds because a faster pace needs more room for footfall and recovery. Wider belts feel steadier, particularly when you step on and off. For reference: the X218's 1,400 × 510 mm is the most generous surface here, and the UREVO's 1,000 × 400 mm is the tightest.
If your sessions are walking with a work-from-home pace, belt length matters less than you would expect, and folded thickness matters more.
Folded Size Is the Real Constraint in Small Rooms
All five machines fold, but the folded thickness ranges from 155 mm to 295 mm — nearly double. Before you buy, measure the space where the machine will live, not the space you will use it in.
You need the folded length and width as well as the depth, plus enough floor clearance to unfold it. Our guide to folding treadmill storage covers where a folded machine realistically goes, and the folding treadmill size guide walks through measuring a room properly before you commit.
One caution on floor types: a machine of this weight needs a flat, rigid surface. On carpet or soft flooring the frame can rock, which affects both comfort and belt tracking.
Starting Safely, Especially at a Higher Body Weight
The NHS advises adults to "do at least 150 minutes of moderate intensity activity a week or 75 minutes of vigorous intensity activity a week", plus strengthening work for all the major muscle groups on at least 2 days a week [1].
Walking counts, and it counts sooner than most people expect. The same guidance notes that "a brisk 10-minute daily walk has lots of health benefits and counts towards your 150 minutes of weekly exercise" [2].
For anyone carrying more weight, the British Heart Foundation's advice is to "start low and slow and to 'listen' to your body" [3]. On a treadmill that means starting at walking pace, building sessions gradually, and treating any joint discomfort as information rather than something to push through. If you have a medical condition or are recovering from an injury, get advice from a qualified healthcare professional before changing your activity level.

Frequently Asked Questions
How much weight can a treadmill hold?
It depends entirely on the model, and the range is wide. The five machines compared here run from 136 kg (300 lb) to 181 kg (400 lb). Cheaper models are often rated lower, so the capacity figure is worth checking before anything else.
Is a higher weight limit always better?
No. A higher limit only helps if you are close to the lower one. If you weigh 100 kg, a 136 kg machine already gives you plenty of margin, and you would be better served by a longer belt or an incline you will actually use.
Do heavier users need a bigger motor?
Not necessarily. Motor power matters most for sustained top speed and incline. A machine rated well above your weight and used at walking pace does not need more power than a lighter-rated one, so prioritise capacity, belt size and stability over headline horsepower.
Should I walk or run on a treadmill if I am a heavier user?
Start with walking and build up. The British Heart Foundation recommends starting low and going slowly, and increasing load or pace before your joints are used to it increases the risk of discomfort that stops you continuing [3].
Is it worth buying a treadmill rated above my weight?
Yes, if the machine also suits the way you will use it. Headroom protects the deck and belt from a load closer to their tested limit, and it means the machine stays comfortable if your weight changes over the years you own it.
Final Word
Choosing the best treadmill for heavier users comes down to finding the right balance between weight capacity, running comfort, workout features and available space. A higher weight limit is important, but the running area, speed range and folding design also deserve consideration.
Whether you prefer walking, running or incline training, choose a treadmill that comfortably supports your body weight and fits your daily routine. Taking the time to compare these features will help you find a practical option for long-term use at home.
