28mm vs 32mm Gymnastic Rings: Which Should You Choose?
Updated 8 October 2026
Four millimetres. That’s the difference. Your hands will notice it more than your workout plan.
Our starting pick: 28 mm. Choose the slimmer grip if you’re buying your first wooden rings and have no strong preference. Choose 32 mm if you already know you like a fuller hold.
28 mm vs 32 mm: what changes?
These measurements describe the thickness of the part you hold, not the width of the whole ring. Atomic Iron’s adult wooden rings have a 235 mm outer diameter in both grip sizes.
28 mm · slimmer grip
Less ring to wrap your fingers around. A practical starting point for first-time buyers or anyone who prefers a slimmer handle.
32 mm · fuller grip
More ring in your palm. Worth choosing if a thicker handle feels better to you; larger hands alone don’t make it compulsory.
Same exercise options. Rows, push-ups and pull-ups don’t require a different programme just because your grip is 4 mm thicker.

- Try both sizes if you can. A gym or friend’s set can help you compare the feel.
- Can’t try them? Use 28 mm as our starting recommendation, rather than guessing from a hand-size chart.
- Training for an event? Check its current equipment requirements. This buying guide is not a competition specification.
Choose your straps separately
Grip size and strap adjustment are different decisions. Standard cam buckles slide to the height you want. Numbered cam straps add reference marks. Quick-Adjust uses carabiners at fixed attachment points.

Quick answers
Are 28 mm rings just for children?
No. The 28 mm option here is an adult wooden ring.
Is one size safer or better for my joints?
Grip diameter alone doesn’t establish that. Choose a comfortable feel and a setup suited to your exercises.
Will 32 mm rings automatically build more strength?
No size guarantees a better result. Choose the grip you want to train with.
Check your selected size, strap option, current price and dispatch notice before ordering. For outdoor materials, compare outdoor rings.
