Find Your Perfect Fit
H&Aquarius rings follow standard US sizing. Most of our rings are available in sizes US 5–8. Compare the inside diameter or finger circumference with the chart below to find your closest size.
Ring Size Chart
| US Ring Size | Inner Diameter | Inner Circumference |
|---|---|---|
| 5 | 15.7 mm | 49.3 mm |
| 6 | 16.5 mm | 51.8 mm |
| 7 | 17.3 mm | 54.4 mm |
| 8 | 18.1 mm | 56.9 mm |
Between sizes? Choose the larger size for a more comfortable fit. Wider bands may also feel more snug than delicate bands.
How to Measure Your Ring Size
Measure a Ring You Own
Choose a ring that fits the finger you plan to wear your H&Aquarius ring on. Measure the inside diameter straight across from inner edge to inner edge, in millimeters. Compare your measurement with the chart above.
Measure Your Finger
Wrap a thin strip of paper snugly around the base of your finger. Mark where the paper overlaps, then lay it flat and measure the length in millimeters. This is your finger circumference; match it to the closest circumference in the chart.
Fit Tips
Measure at the end of the day. Fingers naturally change size throughout the day and with temperature.
Measure the finger you plan to wear the ring on. The same finger can differ slightly between your left and right hands.
Your ring should feel secure, not tight. It should slide over your knuckle with slight resistance.
Wider bands can feel snugger. If you are between sizes, choose the larger option.
For the most accurate fit, check the Details & Dimensions on the individual product page.
Please review our Size Guide and measure carefully before placing your order to help ensure the best possible fit and wearing experience. Choosing the correct size from the start can also help avoid unnecessary returns, additional shipping costs, and delays.
