  • Ensures a properly fitting Oura Ring 4 for maximum comfort, accuracy, and overall experience.
  • Receive a £10 gift card once you've purchased your Oura Ring.


The Oura Ring 4 Sizing Kit allows you to find the ideal size before purchasing an Oura Ring 4. It allows you to try multiple sizes, wear for 24 hours, and find your most comfortable fit. Oura Ring 4 sizes are slightly different from standard ring sizes, so it is important to size. With a sizing kit purchase, you will receive a coupon code to use towards your Oura Ring 4 at checkout. 

NOT STANDARD SIZING — Oura Ring 4 sizes are slightly different from standard ring sizes, so it is important to size yourself using our sizing kit and to follow the instructions provided. Oura Ring is available in sizes 6-13. There are no half sizes.

COMFORT AND ACCURACY — A properly fitting Oura Ring will result in the highest data accuracy, comfort, and overall experience.

CHOOSE A FINGER — Oura Ring 4 works on all fingers and can be worn on either hand. For optimal accuracy, we recommend wearing your Oura Ring on your index finger, middle or ring finger.

HOW IT SHOULD FIT — Oura Ring 4 should fit securely and comfortably at the base of your finger. Your Oura Ring should not rotate as you go about normal daily tasks. We recommend wearing your ring sizer for at least 24 hours to confirm your best fit.

RECEIVE COUPON CODE — With a sizing kit purchase, you will receive a coupon code to use towards your Oura Ring at checkout. The coupon code amount equates to the cost of your sizing kit.

COOL Pillowcases Worth Buying
Color: Champagne, Size: Queen
I bought these to try out, and I was shocked to find they worked out better than my silk pillowcases. I have atopic dermatitis, and I need a pillowcase that doesn't irritate my skin. I also am having hot flashes and need something cool on my face. These pillowcases are perfect for both my conditions. I plan to buy more in different colors. My sons and husband also like it since they are always hot.
