Find Your Perfect Ring Size
Finding the right fit should feel simple. Use our guide to measure your ring size at home and choose your Starline Jewel piece with confidence.
HOW TO MEASURE
Two Simple Ways to Find Your Ring Size
Choose the method that works best for you. Measure a ring you already own for the quickest result, or measure your finger directly if you don't have a ring available.
01 — MEASURE A RING
Measure the Inside Diameter
Choose a ring that already fits the intended finger. Place it flat on a ruler and measure straight across the widest part of the inside opening, from inside edge to inside edge. Record the measurement in millimetres (mm).
TIP: Measure only the inside opening of the ring — do not include the thickness of the band.
02 — MEASURE YOUR FINGER
Measure Around Your Finger
Wrap a thin strip of paper around the base of the finger where you plan to wear the ring. Keep it comfortably snug without pulling it tight. Mark where the ends overlap, then lay the paper flat and measure the length in millimetres (mm).
TIP: Measure the finger at the end of the day when it is typically largest. The paper should fit snugly but still slide comfortably over the knuckle.

Use your measurement from either method above and match it to the chart below. If your measurement falls between two sizes, we recommend choosing the larger size for a more comfortable fit.
