Aria Ring

📏 Find Your Perfect Fit — No Tools Needed

Getting your ring size right is simple, fast, and requires nothing more than a string and a ruler.

Method 1: Perimeter Sizing (Wire or String Method)

Step 1: Wrap a thin, non-stretchy string or wire around the base of your finger — just snug enough to be

comfortable. Mark where the ends meet.

Step 2: Lay it flat and measure the length in millimeters (mm). Then match your measurement with the

guide below:

- Size 5 → 49mm

- Size 6 → 52mm

- Size 7 → 55mm

- Size 8 → 57mm

- Size 9 → 59.8mm

- Size 10 → 62.4mm

- Size 11 → 65mm

- Size 12 → 67.5mm

- Size 13 → 70mm

■ Pro Tip: If you’re between sizes, we recommend sizing up for a more comfortable fit — especially if you’ll

be wearing your smart ring all day.

🔍  Method 2: Use a Ring You Already Own

Step 1: Grab a ring that fits the same finger you plan to wear your smart ring on.

Step 2: Using a ruler or measuring tape, measure the inner diameter (in millimeters) across the center of the

ring. Match your measurement to the chart below:

- Size 5 → 15.7mm

- Size 6 → 16.5mm

- Size 7 → 17.3mm

- Size 8 → 18.2mm

- Size 9 → 18.9mm

- Size 10 → 19.8mm

- Size 11 → 20.6mm

- Size 12 → 21.3mm

- Size 13 → 22.2mm

■ Sizing Tip: Lay your ring flat on a hard surface to ensure the most precise measurement.
