How to Use a Ring Sizer

How to Use a Ring Sizer

Sizing makes buying rings online more difficult than other jewelry. Unlike necklaces, which are are pretty straightforward - check out our blog on necklace sizing to see why! - rings require a bit more precision.

Luckily, we've found some pretty handy tools that make it easy. If you use a ring sizing gauge, it’s as simple as can be! 

The ring sizing gauge we like best, and sell here online, looks a lot like a standard zip tie that you'd find at a hardware store. It's printed with ring sizes 1-16, as used by most jewelers in the U.S., Canada, and Mexico. 

To use the gauge, start by threading the gauge so it forms a loop, then put the gauge on the finger that you want to wear your ring on. Tighten the gauge slightly so it feels comfortable. One of our users with bigger fingers recommends that you put the gauge on the thickest part of your finger and make a fist. The gauge will pop up a few sizes and the size given may be more comfortable for you.

Then make a fist-the gauge may pop up a size!


Make sure that the gauge can be slid on over your knuckles, then note the number that the arrow is pointing at. In the image below, the gauge indicates that the correct size is a 10.5.

Signpost Ring

The Signpost Signet Ring has a wide 7mm band - slightly thicker than the gauge. Rings with wider bands can feel a bit more snug going over your knuckles. For example, I normally wear a size 6 on my ring finger, but I wear a rather petite wedding band and a size 7 Signpost Signet Ring feels much more comfortable going over my knuckles. When in doubt, go up a half size!

Other Ring Sizing Recommendations

Another easy option to determine your ring size is to stop by a local jeweler. Many jewelers have a ring sizing tool that allows you to test different sizes to see what feels best. Of note, there are many different personal preferences, some people prefer that rings fit snug, while others fingers may swell up if the ring is too tight. Listen to your inner voice - that will go a long way in helping you select the right size for YOU.
