Oura ring dimensions and weight:
The Oura ring in size 8 measures 16.8 mm or 0.31 inches and weighs 0.15 ounces. The full Oura rings’ weight ranges between 0.1 and 0.2 ounces (4-6 grams). Oura Ring sizes are slightly different than standard US ring sizes
Let’s explore how you can find out your ring size without ordering a sizing kit.
If you go to any nearest local jewelry shop, you can use the standard wide-band US ring sizer to find your size. If you are outside the US, use the conversion chart to convert the ring size into the US ring size.
If you own an Oura ring already, use that as a reference to order your 2nd or 3rd Gen Oura ring to get proximity of size.
If you have a 3D printer, you can print a ring sizer of your own but for that, you may need to use high-quality materials to ensure a smooth finish.
You can try to wrap a string or paper around your finger and use it to find the ring size. Make the intersection of the ends with a pen. Find the diameter of the ring, measure the string or piece of paper with a ruler, and then divide the result by 3.14 ( or Pi ). Now, look at the charge and choose the closest measurement to find the ring size.
When measuring, ensure your fingers are warm because weather impacts the finger size and in cold temperatures and early morning you will get smaller digits. Similarly, your dominant hand’s fingers are slightly bigger than the other hand’s.
