Walking Pad vs Treadmill: Which Should You Buy in the UK?

A walking pad is a slim, handrail-free treadmill made for walking, usually capped at 6 km/h, while a full treadmill is a bigger machine with a console, handrails, a longer deck and a top speed of 16 to 20 km/h. If you want more steps while you work and you don't plan to run, buy a walking pad. If you want to jog, run, do intervals or walk on a steep incline, buy a treadmill, because no walking pad will do those jobs well.

That's the short version. The longer one comes down to six numbers: deck size, top speed, motor, incline, weight limit and the space you have. Here's how they compare, with real figures from models sold on Amazon UK.

The most telling row is the deck. A walking pad belt of 40 x 120cm is plenty for a walking stride. Once you start running your stride lengthens a lot, and that's why proper running treadmills sit at 140 to 150cm long and around 50cm wide.

Deck size: the difference you feel first

Walking pads keep the deck short and narrow to stay light and easy to store. The KingSmith WalkingPad C2 has a 120 x 40cm belt, and the WalkingPad Z1 is 121 x 40cm. Some budget pads go smaller still: the UREVO 4-in-1 desk treadmill has a 100 x 40cm running area, and the cheapest CITYSPORTS pad is 38 x 102cm.

Compare that with a home running treadmill. The Reebok FR30z has a 150 x 51cm deck, which is about 25% longer and 11cm wider than the C2. That extra width matters more than people expect. On a 40cm belt you have to walk in a fairly straight line, and the odd foot clips the side rail, especially if you're looking at a screen rather than at your feet.

Walking short, steady steps at a desk, you won't miss the extra length. Taller users above about 6ft, or anyone with a long natural stride, will feel cramped on anything under 120cm.

Top speed and running

Here the two machines part ways completely. Nearly every walking pad tops out at 6 km/h, which is about 3.7mph. That's a brisk walk for most adults and a 10-minute kilometre. You can't jog at it.

A few 2-in-1 pads with a fold-up handrail reach 10 to 12 km/h. On paper that's a jog. In practice the deck is still the same short, narrow belt, the motor is working near its limit and the frame moves more at speed. We cover the details in can you run on a walking pad, but the honest answer is: only gently, and only now and then.

Treadmills start where walking pads stop. Most folding models reach 16 km/h, and the FR30z goes from 0.5 to 20 km/h. That covers everything from slow recovery walks to 5K pace and sprint intervals.

Motor and build

Walking pads use small brushless motors because they only need to turn the belt at walking pace, often for hours on end. Brushless motors are quiet, which is why a pad like the C2 sits around 48 dB at a normal pace and you can take calls on it.

Treadmill motors are bigger because running puts much higher loads on the belt with every footstrike. Look for the continuous rating, not the peak. The FR30z, for example, is marketed at 4.0 HP but is listed as 2.0 CHP continuous, and the continuous figure is the one that tells you how it copes with sustained running. Treadmills also add proper cushioning systems under the deck, which you'll appreciate at running speeds.

Incline

Most walking pads are flat. A handful have a manual tilt you set before you start, like the 4% incline on the CITYSPORTS pad, and a few premium desk models offer a powered incline: the UREVO 4-in-1 goes to 9%. They're the exception.

Treadmills almost always have a powered incline you can change mid-session, commonly 12 to 15 levels, and dedicated incline machines go further. If you like hill walking for fitness or want to raise your heart rate without running, incline is the reason to choose a treadmill. A 6 km/h walk on a flat belt is light exercise. The same walk at 10 to 12% is hard work.

Weight limit

Budget walking pads are usually rated for 100 to 120kg, mid-range pads 120 to 136kg, and a smaller group of heavy-duty pads 150 to 180kg. The C2 is rated at 100kg and the Z1 at 110kg. Folding treadmills typically start around 120kg, and the FR30z takes 150kg.

Whichever you buy, leave 15 to 20% headroom above your body weight. Our walking pad weight limit guide explains why, and which specs show a pad is built to cope with a heavier user.

Space, storage and moving it

This is where walking pads win clearly. A walking pad weighs 20 to 30kg, stands only 12 to 16cm tall and has no console. The Z1 is 142.5 x 56 x 10.6cm unfolded and folds to 81 x 56 x 13.8cm. One person can tip it on its wheels and roll it under a bed or stand it against a wall.

A folding treadmill is a piece of furniture. Even folded it takes a footprint of roughly 1 square metre and stands well over a metre tall. The FR30z weighs around 80kg, so moving it between rooms is a two-person job. If you live in a flat and need the floor back every evening, that alone can settle the decision.

Price on Amazon UK

At the time of writing (prices move often):

• Budget walking pads: about £100 to £150 for basic flat pads.
• Mid-range walking pads: about £200 to £320. The Mobvoi Home Walking Treadmill usually sells for around £200, and the WalkingPad Z1 is around £319.
• Budget folding treadmills: about £200 to £400 for 14 to 16 km/h machines with a modest motor.
• Mid-range running treadmills: about £700 to £1,000. The FR30z sits at around £899.

So a good walking pad costs about the same as a cheap treadmill. If you're torn at the £250 to £350 mark, ask what you'll do on it most. A quality walking pad will do walking better than a budget treadmill. A budget treadmill will do running better than any walking pad.

Under-desk use

A walking pad is built to go under a standing desk: no handrails, no console in the way, and a remote or app to change speed. A normal treadmill doesn't fit under a desk at all, because the console and uprights sit exactly where your keyboard would be.

Does walking while you work actually help? A 2021 meta-analysis of 13 treadmill desk studies found users burned about 105 extra calories an hour compared with sitting in lab settings (Oye-Somefun et al., BMC Public Health). The real-world effect on sitting time in workplace trials was small, though, and the authors found no clear change in blood pressure. A walking pad helps if you use it, and it doesn't replace proper exercise. We set out how to make it part of your day in our walking pad under desk guide.

Pick a walking pad if...

• You mainly want more daily steps, especially while working at a standing desk.
• You have little floor space and need the machine out of sight between sessions.
• You walk rather than run, and 6 km/h is fast enough for you.
• You want something quiet enough for video calls or a flat with neighbours below.
• Your budget is under about £300 and walking is the goal.

If that's you, start with our best walking pad UK picks. If you want incline too, the UREVO SpaceWalk 5L adds up to 9% for around £350; read our UREVO SpaceWalk 5L review first.

Pick a treadmill if...

• You want to jog or run, even a couple of times a week.
• You want interval training or a powered incline for hill walking.
• You're over about 6ft or have a long stride.
• You weigh more than 110kg and want a sturdier frame and deck.
• You have a spare room or garage corner where it can stay set up.

Our verdict

For most people working from home, a walking pad is the better buy. It's cheaper, it gets used because it sits under the desk rather than in the spare room, and steady walking is what most of us need more of. If you're still unsure whether you'd use one, read are walking pads worth it first.

Buy a treadmill the moment running, intervals or real incline are on your list. No walking pad covers them properly, and a 2-in-1 that claims 12 km/h is a compromise you'll outgrow quickly. If you want both desk walking and running, the honest answer is two machines, or a treadmill and a lot of discipline about getting on it.
