How to Choose the Best Oura Ring Gen 4
Decide between generation 4 and generation 5 hardware
The Oura Smart Ring 4 models offer an 8-day battery life and come in classic metal finishes like Gold and Silver, alongside Ceramic Petal and Ceramic Tide choices. If you want the smallest physical hardware, Oura Ring 5 Silver features reconfigured, larger sensors packed into a scaled-down body for greater accuracy. Keep in mind that Oura Ring 5 requires its own specific sizing kit rather than the Oura Smart Ring 4 Sizing Kit.
Choose between metallic and ceramic finishes
Standard variants like the Oura Smart Ring 4 Silver and Gold offer compact metallic designs with convenient wireless charging. If you prefer a non-metal exterior, options like the Oura Ring 4 Ceramic Petal and Ceramic Tide provide distinct ceramic styling while maintaining the same 8-day battery life and Smart Sensing tracking across 50 health metrics.
Confirm your finger size with a sizer before buying
Oura ring sizes do not match standard jewellery sizes, making accurate measurement essential prior to purchase. Ordering the Oura Smart Ring 4 Sizing Kit allows you to test custom sizers at home, and the kit cost is provided back as a credit towards your ring purchase. Remember that sizing kits are non-returnable and the Oura Ring 5 Silver demands a different sizer to the Gen 4 range.
