How to Choose Your Orbit Smart Ring Size
Product guidance from SnapPal. Follow the instructions supplied with your specific device.
A smart ring needs a comfortable fit for everyday wear and sensor contact. Orbit is available in US sizes 6–12. Before choosing a color or pattern, take a moment to check the size of the finger you plan to wear it on.
Measure the inside, not the outside
Use a ring that fits your intended finger comfortably. Place it flat and measure directly across the inside opening with a millimeter ruler. Do not include the metal edges in your measurement. An outside diameter measures the band too and can lead to the wrong size.
Find your Orbit smart ring size
Measure the inner diameter of a ring that fits your intended finger comfortably. Measure straight across the inside opening in millimeters, excluding the metal band. Compare it with the Orbit chart below.
| US size | Inner diameter |
|---|---|
| 6 | 16.5 mm |
| 7 | 17.3 mm |
| 8 | 18.2 mm |
| 9 | 19.0 mm |
| 10 | 19.9 mm |
| 11 | 20.6 mm |
| 12 | 21.5 mm |
Choose a snug, comfortable fit that keeps the sensor against your skin. The ring should not pinch or restrict normal movement. If you are between sizes, contact us before ordering rather than guessing.
Adjustable bracelet fit
The Orbit Smart Bracelet uses an adjustable sliding closure. Gently move the slider along the chain to loosen or tighten the bracelet. Choose a comfortable fit with sensor contact; there is no fixed wrist-circumference size to select.

Choose style after fit
Orbit includes 21 style and color options, from classic finishes to Crystal Line and Ornate patterns. The design name does not replace the size selection: check both options before adding your ring to the cart.
