5 mm vs 3 mm Yoga Mat Thickness: What to Know
Written and reviewed by The Kriya Yogi · Updated 2 October 2026
The short answer
Choose a 5 mm mat, like the ones we carry, if you want reliable cushioning for knees and wrists during a standard home or studio practice. Consider a thinner 3 mm mat, more common for travel, only if portability matters more to you than joint comfort and floor stability.
What matters for this
- Thickness
- A: 5 mm · B: 3 mm (travel-style, general market)
- Cushioning
- A: Noticeable padding for knees and wrists · B: Minimal padding
- Floor feedback
- A: Balanced, still grounded · B: Higher, closer to bare floor
- Portability
- A: Standard mat bulk · B: Rolls smaller and lighter
- Our range
- A: Cork, linen and rubber mats, all 5 mm · B: Not currently offered
- Best use
- A: Everyday home or studio practice · B: Travel, external studio use
What thickness actually changes
Mat thickness is mostly a trade-off between joint cushioning and a stable sense of the floor. At 5 mm, knees and wrists get real padding during kneeling poses, table positions and planks, while the mat still stays stable enough that balance poses don't feel wobbly. A 3 mm mat gives less protection to bony joints but puts you closer to the actual floor, which some practitioners prefer for better proprioception in standing balance work.
Why all three of our mats are 5 mm
We carry cork, linen and natural rubber mats, and every one of them is built at 5 mm rather than offering a thinner option. That reflects a straightforward choice: for a primary practice mat used regularly at home or in a studio, 5 mm gives a more universally comfortable balance of support and groundedness than going thinner, without becoming so thick that balance poses feel unstable.
When a thinner mat makes sense
A 3 mm mat is typically chosen for travel, since it rolls into a smaller, lighter bundle that fits more easily into a suitcase or day bag. If you already own a primary mat at home and simply want a slim travel companion for occasional use, a thinner mat bought elsewhere for that specific purpose is a reasonable addition rather than a replacement.
Cushioning versus stability in practice
It's worth noting that more thickness is not automatically better: mats built much thicker than 5–6 mm can start to feel unstable under standing balance poses, since the foot sinks slightly into a deep surface. 5 mm sits in the sweet spot most practitioners settle on for regular use, which is why we don't offer either an unusually thin or unusually thick alternative across our mat range.
Choose something else if…
- Practitioners seeking an ultra-thin travel mat — we do not currently stock a 3 mm option.
- Anyone wanting maximum cushioning beyond 5 mm for sensitive knees; consider adding a folded blanket instead.
