Here's a guide to getting your perfect size for the Smart Ring.

Getting the perfect size for a smart ring is crucial for accurate data tracking and comfortable daily wear. Unlike a traditional ring, a smart ring's sensors need constant, snug contact with your skin to properly measure things like heart rate and blood oxygen

Here's a comprehensive guide on how to get your perfect smart ring size:

General Sizing Best Practices 

Here are the tips will help you make the best decision:

• Choose the Right Finger: Smart rings can be worn on any finger, but for optimal accuracy, most brands recommend wearing it on your index, middle, or ring finger
• Go for Snug, Not Loose: A smart ring should not be able to freely rotate on your finger. If it can, the sensors won't have consistent skin contact, leading to inaccurate data.
• Consider Natural Swelling: If you're between sizes, remember that your fingers can swell. It's often recommended to go with the slightly larger size, especially if the smaller one is uncomfortably tight when your fingers are warm or swollen.
• Non-Dominant Hand: For activity tracking, wearing the ring on your non-dominant hand can help reduce "false positives" from fidgeting or arm movements, which can be misidentified as steps.

Use a Sizing Chart: Find a standard ring size chart online and measure the circumference of your finger with a flexible tape measure or a strip of paper.

Measure an Existing Ring: Find a ring you already own that fits well on the intended finger and measure its internal diameter.
