The Oura Ring 5 Sizing Kit is the easiest and most accurate way to find the right fit before purchasing your Oura Ring 5. A properly fitting ring improves comfort, long-term wearability, and the accuracy of your health data, helping you get the best possible Oura experience.
NOT STANDARD SIZING - Oura Ring 5 sizes differ slightly from standard ring sizes and previous Oura Ring generations. Oura Ring 5 is available in sizes 6–13 with no half sizes.

HOW IT SHOULD FIT - Your Oura Ring 5 should fit securely and comfortably at the base of your finger without rotating easily during normal daily activities.
WEAR TEST - Fingers naturally expand and contract throughout the day. Oura recommends wearing the sizing ring for 24 hours to confirm your best fit.
MATERIALS - The sizing rings are made from plastic, while the final Oura Ring 5 is crafted from durable, scratch-resistant titanium for a more refined and comfortable feel.

Only a sizing kit so
Only a sizing kit so not much to say but helpful none the less.

Good
The Oura Ring 5 Sizing Kit was useful for finding the right size, however, I purchased it because it was advertised with a £10 voucher towards the purchase of an Oura Ring. Unfortunately, I have not received the voucher.

Useful sizing kit
Really recommend purchasing this beforehand. Comes with all of the sizes and ensures you can get the right fit and select the finger you want to wear it on.

Easy to use
The sizing kit was very helpful and made it easy to find the right ring size before ordering. The sample rings were comfortable to wear, and I could test different fingers throughout the day to make sure I chose the best fit. It gave me confidence that I was ordering the correct size. Highly recommended before buying the Oura Ring.

The best wellbeing website…
The best health and wellbeing website in the UK. The range of products is fantastic, even on hard to reach USA products. I love the subscription service too. I'd be lost without this website.

Amazing!
Healf isn't just another wellbeing brand. They really get it. The products are fantastic, and the support is always so personal and genuine!
Janet
Great products, service, and customer support
Healf have a great range of wellbeing products not available elsewhere in the UK. They are competitively priced as one-off, but even better if you take up the 'subscription' which is super flexible too. I'd have no hesitation in recommending Healf.

I love Healf
It's the only place I get really decent health and wellbeing brands, particularly US brands. I've bought a Pvolve set, lots of Skinny Confidential stuff, Thorne supplements etc., the really great stuff that's impossible to get otherwise.
