Simple Steps to Find Your Ring Size
Gather Your Tools
Use a ruler, strip of paper or string, and a pen to measure an existing ring or your finger.
Wrap & Mark
Wrap the strip around your finger and mark where both ends meet.
Measure the Length
Lay it flat on a ruler. This measurement is your finger circumference. Divide by 3.1416 for diameter.
Find Your Size
Compare your measurement with our chart or use the interactive size calculator.

Factors That Affect Your Ring Size Reading
- Time of day: Fingers run smaller in the morning and swell as the day goes on. Measure in the evening if you want the size you'll actually live with day to day.
- Temperature: Cold shrinks fingers; heat and humidity do the opposite. Skip measuring right after you've been out in freezing weather or straight out of a hot shower.
- Dominant hand: The fingers on your dominant hand tend to run slightly bigger than the other hand's.
- Knuckle vs. base of finger: If your knuckle is a little bigger than the base of your finger, size for getting the ring over the knuckle comfortably, not just a snug fit at the base.
- Salt, exercise, and pregnancy: All three cause temporary swelling. Don't measure right after a workout or a salty meal.
- Band width: Wide bands (6mm+) fit snugger than thin ones at the same marked size, since more metal touches your finger. Going wide? Size up half a size.
Buying a Ring as a Gift (When You Don't Know Their Size)
- Borrow a ring they already wear on the right finger and measure it with the method above. Return it before they notice.
- Ask someone close to them. A friend or family member may already know, or can find out without tipping your hand.
- Trace a ring they own onto paper, then hold that traced circle against a printed size chart.
- When in doubt, size up. A loose ring is easier, and often cheaper, to resize down than a tight one is to resize up.
- Use Shop LC's Ring Resizing Service as a safety net. Most requests get reviewed within 1–2 business days.
