Treadmill Mat: Do You Need One, What Size and How Thick?

Do you need a treadmill mat? Not strictly, because a treadmill will run on a bare floor, but a mat costs £15 to £40 and solves several slow, expensive problems at once. On carpet it keeps fibres and dust away from the motor and stops the frame sinking unevenly. On wood, laminate or vinyl it stops scratches, rubber marks and lube drips, and it takes some of the edge off the vibration that reaches whoever lives downstairs. Buy one that's bigger than the base of your machine, 4mm thick for hard floors or 6mm for carpet, and you're covered.

The rest of this guide covers when a mat really matters, how to measure for one, which thickness and material to pick, and what's different for walking pads.

Do you actually need a treadmill mat?

It depends on the floor, so we've split it that way.

On carpet

This is where a mat matters most. Treadmills pull cooling air in near the floor, and deep pile closes that gap while the belt and fan draw in fluff, pet hair and dust. Sole's F63 manual tells owners to vacuum underneath the treadmill every month because dirt there "can get sucked up" into the parts under the motor cover, and it warns against using the machine on deeply padded, plush or shag carpet at all, saying damage to both carpet and treadmill may result (Sole F63 owner's manual). A mat gives you a smooth surface you can actually vacuum and a level base for the feet.

Carpet also builds static with a moving belt and rubber-soled trainers, and it takes deep dents from the feet. We've covered all of this in detail, including when you need a plywood board under the mat, in our guide to putting a treadmill on carpet.

On hard floors

People often skip the mat on hard floors because there's no fluff to worry about, and that's usually a mistake. The risks are different but just as real:

• Scratches and dents. A treadmill shifts a few millimetres with every footstrike, so the feet slowly grind grit into wood and laminate.
• Rubber marks. Rubber feet and rear rollers can leave dark marks or yellowish stains on vinyl, LVT and light-coloured floors that don't scrub off.
• Belt dust and lube. Sole's manual notes that black dust from the belt sometimes appears on the floor behind the treadmill and calls that normal. Add the odd drip of silicone lube from the edges of the deck and a light floor will show it within weeks.
• Noise and vibration. Footfall noise travels through the floor structure rather than through the air. Horizon's treadmill user guide points out that a wood floor reverberates more than carpet over concrete and says a heavy rubber mat can help reduce reverberation through the floor (Horizon Series treadmill user's guide).

A thin PVC mat handles the first three. For the fourth, especially in a flat or an upstairs room, you'll want something thicker and denser (more on that below).

What about the warranty?

We checked manuals from Sole and Horizon and neither makes a mat a condition of the warranty, so we won't tell you a mat protects your cover. What the Sole manual does say is that carpet type and dirt build-up can cause damage, and a warranty assessor will read the same manual you have. Check yours for wording about carpet, air vents and floor protection before you set up.

How to measure for a treadmill mat

The commonest mistake is buying a mat that's a few centimetres short. The rear rollers end up half on and half off, the deck sits at a slight angle, and you've made things worse than no mat at all.

1. Measure the base, not the handrails. Run a tape along the longest point of the frame that touches the floor, from the front wheels or feet to the rear rollers. Then measure the widest point at floor level. Upright rails and console arms can be wider than the base, and the mat only needs to cover what sits on the floor.
2. Add about 15cm to both numbers. That leaves roughly 7cm on each side, enough to catch drips and keep the feet well away from the edge.
3. Check the folded position. If you fold the treadmill and roll it on its wheels, make sure those wheels still land on the mat when it's upright.
4. Keep the clearance behind it. Sole asks for at least 3.5 feet (about 1.1m) clear behind the treadmill. The mat doesn't change that, so don't push the machine back to the wall to fit a smaller mat.

As a rough guide, walking pads need about 150 x 75cm, most folding treadmills need around 180 x 80cm, and large non-folding machines often need 200 x 100cm or more. NordicTrack's own large equipment mat is 216 x 107cm in vinyl (NordicTrack UK floor mat), which tells you how big a long-deck running machine can get.

How thick should a treadmill mat be?

Thickness should follow the floor, not the price.

Mat	Best for	Watch out for
4mm PVC	Hard floors, tight loop carpet	Does little for noise; feet can press through medium pile
6mm PVC	Most carpet, walking pads, general use	Plastic smell for a week or two
10mm+ dense rubber	Upstairs rooms, flats, heavy machines	Heavy, pricier, strong smell at first
EVA foam jigsaw tiles	Floor exercise areas, not treadmills	Dents under the feet, joins separate

On a hard floor a 4mm mat is all the protection you need. On carpet, 6mm is the sweet spot because it spreads the load from each foot without letting the machine rock. Going thicker only helps if the mat is dense; a thick, soft mat lets the feet sink at different rates, which is exactly the wobble you were trying to avoid.

PVC, rubber or foam?

PVC covers most mats under £40. It's firm, waterproof and easy to wipe, and it's what NordicTrack uses for its own mat. The downsides are a plastic smell when new and corners that curl after weeks folded in a box. Unroll it in a warm room for a day or two before the treadmill goes on.

Rubber is heavier, grips better, damps more vibration and shrugs off dents. It's the one to pay for if you're upstairs or in a flat, though a large rubber mat is a two-person job to move. Some black rubber can transfer colour onto very light carpet, so check the listing.

EVA foam tiles are the one to avoid directly under a treadmill. They're light and cheap, but they compress permanently under the feet and creep apart with vibration. If you're kitting out a whole room, look at proper rubber gym flooring instead and put the treadmill on that.

Walking pad mats

Walking pads need a mat at least as much as a full-size treadmill does. The whole machine sits only a few centimetres off the floor, so on carpet the motor housing is almost in the pile, and on hard floors the thin frame passes more vibration straight into the boards. A flat 6mm mat around 150 x 75cm suits nearly every walking pad we've covered, including the MERACH 12% incline walking pad.

If your pad lives under a desk, check the mat fits between the desk legs and that the desk can still go high enough with the extra few millimetres. Our guide to setting up a walking pad under a desk covers desk height and positioning.

Two treadmill mats worth buying

We haven't tested these mats ourselves. We chose them from Amazon UK listings by size, thickness and stock, and both were in stock when we checked on 31 October 2026.

For full-size treadmills on hard floors: the OZE SPORTS treadmill mat is 180 x 75cm and 4mm thick. With our 15cm margin it suits a base up to about 165cm long and 60cm wide, which covers plenty of folding treadmills. Measure first: wider machines need a 200 x 100cm mat, and on thick carpet you'd want 6mm.

Check the OZE SPORTS mat on Amazonaround £14

For walking pads and compact treadmills, or any carpet: the HAPBEAR treadmill mat is 152 x 76cm and 6mm thick, which fits a base up to roughly 137 x 61cm. That's most walking pads and smaller folding machines, and the extra thickness suits carpet.

Check the HAPBEAR mat on Amazonaround £36

For a long-deck running machine such as the Sole F80, measure carefully; you'll probably need a 200 x 100cm mat or a brand mat like NordicTrack's.

Common mistakes

• Buying by treadmill name rather than measurement. Listings say "fits most treadmills", but a few centimetres matter.
• Leaving a curled mat to flatten under the machine. It won't flatten evenly. Let it relax first, then level the treadmill on top.
• Forgetting to re-level. Once the mat is down, push on each corner and adjust the feet until nothing rocks, then check belt tracking at walking pace.
• Never cleaning under it. Lift the front, vacuum the mat and the floor every month or so, and while you're down there check whether the belt needs attention. Our guide on how to lubricate a treadmill shows how.
