Q: How does the Oura ring 4 and 5 differ?

submitted by ring lover - 1 month ago

  • A: The 5 is 40% lighter/smaller than the 4 and is all titanium and shows less scratching than the 4

    submitted byYes - 1 month ago

  • A: Hi, thanks for reaching out about Oura Ring 5 Sizing Kit. The Oura Ring 5 mainly builds on the Oura Ring 4 with incremental improvements rather than a complete redesign. Differences typically include enhanced sensors for more accurate health tracking (like sleep, heart rate, and readiness scores), improved battery efficiency, and updated software features/algorithms for better insights. The overall look, size options, and general functionality remain very similar, so sizing kits are used in the same way for both generations. If you have any additional questions, we welcome you to contact MyTGTtech at 833‑848‑8324 every day, between 7am–11pm CST.

Easy and helpful

This was very helpful in determining my ring size. It arrived next day, which was very fast. I do feel that the gen 4 fits me the same as gen 5, but it was important to confirm that since Oura shared that sizing would not be the same as previous rings.

I received the kit for the Oura Ring 4 and got no help exchanging for the actual Ring 5 sizing kit.
