Find your VOXOR size

VOXOR — seven precision sizes from #7 to #13, with inner diameter and circumference reference

Seven sizes availableVOXOR Pro fits a range of fingers from size 7 to 13 — pick yours at checkout.
Two quick ways to find itMeasure your finger with a paper strip (see Measure Now, 60 seconds) or convert from your existing UK / EU ring size (see Conversion Table).

How should it feel? Snug just over the knuckle, secure at the base, no spinning. A small finger movement should still be possible.

Find your size in 60 seconds with a paper strip and a ruler. We’ll match the circumference to the closest VOXOR size.

Three steps: wrap a paper strip around your finger, mark where it overlaps, measure the length in millimetres.

Your estimated VOXOR size

—

For best accuracy, measure twice at the end of the day — fingers swell with warmth and activity, so pick the size comfortable in both states.

Tip: measure at the end of the day, twice, and use the larger reading.

If you already know your standard ring size, find the closest VOXOR size below. Smart rings use a slightly different geometry — double-check with Measure Now if unsure.

VOXOR	UK	EU	Inner ø	Circumference
7	N½	54	17.3 mm	54.3 mm
8	Q	57	18.1 mm	56.9 mm
9	S	60	18.9 mm	59.5 mm
10	T½	62	19.8 mm	62.1 mm
11	V	65	20.6 mm	64.6 mm
12	X	67	21.4 mm	67.2 mm
13	Z	70	22.2 mm	69.7 mm

UK letters and EU numbers are approximate equivalents. For best accuracy, measure your finger directly with the Measure Now tool — ring fit varies by finger shape and time of day.

Track your health, sleep and recovery 24/7 — without distractions. VOXOR keeps you focused on performance, not notifications.

Best sleep tracker I’ve used

Honestly didn’t expect to like a ring tracker, but the sleep insights are spot on. I finally understand why I wake up tired — and the app is so simple. No monthly fee was the dealbreaker for me.

Charlotte W. — Manchester
Changed how I train

Switched over from a Garmin watch. The morning recovery score has genuinely changed how I train — green I push, red I rest. Battery easily lasts me four days and charges in 30 minutes.

James R. — Bristol
You forget it’s on

Lightweight and I genuinely forget it’s on my finger. Wore it in the shower and the sauna with no issues. Customer service answered my sizing question in under an hour. Couldn’t fault it.

Emily H. — Leeds
Same metrics, no subscription

Spent weeks comparing this to the Oura. Tracks the same stuff — sleep, HRV, recovery — without the £5.99 a month. Charges flat in 30 minutes. Wish I’d bought one a year ago.

Oliver T. — London
Goodbye notifications

My Apple Watch was burning me out with pings. The Voxor just tracks — no screen, no buzzing. My sleep score and HRV have actually improved since I started wearing it instead.

Sophie M. — Edinburgh
Premium feel, fair price

Took it sea swimming in Cornwall last month — completely fine. Heart rate matches my Polar chest strap within a couple of bpm. The stainless steel feels properly premium for £49.

Daniel K. — Birmingham
