Ring Sizing at Home

Amazonite and White Sapphire ring

Let me guess... You don't have time to stop by your local jeweler to have your ring sized, or you enjoy the convenience and just feel safe when you can tackle these small obstacles at home. Either way, I've got a couple quick solutions to keep you poppin on the ring bling.

Create Your Own Ring Sizer

For this activity, we're measuring in millimeters. The metal thickness or gauge of a ring, as well as the diameter of a ring is typically measured in millimeters.

1) Cut a strip of paper or a piece of non stretchy string long enough to circle around your ring finger. The width of the paper must be the same width of the ring you'd like to purchase. If you're uncertain, just use a standard 3mm width.

2) Wrap around your finger until it feels comfortable, but keep the paper as snug as a ring band would fit. Not so tight that you think it will tear, but snug! Mark where the two ends overlap.

3) Check that the paper or string slips over your knuckle. It MUST slip over your knuckle.

4) Measure the distance between the two marks. This is the inside circumference and it's found on the middle column of the chart below. Now, follow the chart from left to right and find your size.

NOTE: If the ring is over 3mm wide, then measure again using the correct ring band width, or order approximately a half size up. Wider ring bands require a larger ring size!

Measure a Current Ring

If a ring fits well on the finger you're purchasing for, use a ruler to measure the inside diameter of this ring. Ensure it's a round band that hasn't been bent or dented for accuracy. Measure in millimeters, straight across the inside of the ring from edge to edge, then use my conversion chart above to find your size.
