How to Measure Your Ring Size at Home

Measuring your own ring size is easy with a few simple tools and techniques.

Use a Piece of String

This is the most common DIY ring sizing method. Here's how it works:

  1. Cut a piece of string, floss, or thin yarn about 6 inches long.
  2. Wrap the string snugly around the base of the finger you'll be wearing the ring on. The string should fit just below the knuckle.
  3. Mark the spot on the string where the ends overlap with a pen or marker.
  4. Lay the string flat and use a ruler to measure from the end of the string to the mark in millimeters. This is your finger's circumference.
  5. Match your measurement to the ring size chart below to determine your size.

If the string overlaps between two sizes, round up to the larger size for a more comfortable fit. Make sure the string is pulled snugly but not too tight - you don't want to cut off circulation!

Use a Strip of Paper

You can also measure your ring size using a strip of paper:

  1. Cut a strip of paper about 4 inches long and 1/2 inch wide. Regular printer or scrap paper works well.
  2. Wrap the paper around the base of your finger, just below the knuckle.
  3. Mark where the ends of the paper overlap with a pen or marker.
  4. Lay the paper flat and use a ruler to measure from the end to the mark in millimeters.
  5. Match your measurement to the ring size chart below.

As with the string method, round up if your measurement falls between sizes for the best fit. Make sure the paper strip is snug but not painfully tight.

Use a Ring You Already Own

If you have a ring that fits the finger you'll wear your new Gold Presidents ring on, you can use that to measure:

  1. Slide the ring onto the correct finger. Make sure it's a ring that fits well - not too loose or too tight.
  2. Use a soft measuring tape or ruler to measure the inside diameter of the ring in millimeters. Measure across the bottom of the band, not including the metal edges.
  3. Match this measurement to the ring size chart below to find your size.

This method is quick and easy if you have a suitable ring to use for measuring. Make sure to measure several times for accuracy.

Ring Size Measurement Tips

  • Measure at the end of the day when your fingers are largest.
  • If your knuckle is larger than your finger base, take two measurements and size between them.
  • Measure your dominant hand, which is usually slightly larger.
  • Measure 3-4 times for consistency.
  • Make sure your hands are at normal temperature - not icy cold or hot.
  • If between sizes, size up for comfort. Rings should slide over the knuckle easily.
  • For surprises, borrow a ring your partner wears on the correct finger.

Frequently Asked Ring Sizing Questions

What if my measurement falls between two sizes?

If your diameter measurement lands between two ring sizes, we recommend sizing up to the larger size. It's better for rings to be slightly big rather than too small for comfort.

How tight should my ring fit?

The right fit is snug enough that the ring won't slip off or spin around on your finger. But it shouldn't be painfully tight or cut off circulation. You should be able to slide it on and off over your knuckle with only minor resistance.

Should I measure my dominant hand?

Yes, you should measure the finger on your dominant hand, as that finger is usually slightly larger. Most people wear wedding bands and engagement rings on their non-dominant hand though.

When is the best time of day to measure?

Measure your ring size at the end of the day when your fingers are largest. Your fingers swell and expand during the day and shrink in the morning and in cold temperatures.

What if my knuckle is a lot bigger than my finger base?

Take two separate measurements - one around your knuckle, and one around the base of your finger. Then size your ring in between the two measurements.

How will I know I have the right size?

A properly fitted ring should slide over your knuckle and then fit snugly and comfortably on your finger. It shouldn't spin around or slip off easily. If it feels too loose or tight, you likely need a different size.

Does band thickness affect ring size?

Yes, a thicker ring band can subtly reduce the inner diameter of a ring. If choosing between two sizes, go with the larger size for a thicker band.

What is the average ring size for women?

The average women's ring size is size 7 in the US. Sizes 6-8 are the most common.

What is the average ring size for men?

The average men's ring size is size 10 in the US. Sizes 9-12 are common.

Can I measure a ring I already own to find my ring size?

Yes, you can use a ring you own that fits that finger to measure the inner diameter and determine your size. Make sure it fits well - not too loose or tight.

Are men's and women's ring sizes on the same scale?

Yes, men's and women's ring sizes are measured using the same numerical scale, which corresponds to inner diameter in millimeters.

How do I secretly find out someone's ring size?

Ask a close friend or family member to subtly measure their finger or borrow a ring they wear on that finger. Or trace the inner circumference of one of their rings on paper when they aren't around.
