How to find out your Ring size Without Measuring?

Jul 05 2025 0 comments

Whether you’re buying a ring for yourself or planning a surprise proposal, knowing the correct ring size is key to getting that perfect fit. At KRK Jewels, we often get asked: “How do I find out a ring size without measuring?” or “How can I find someone’s ring size without asking them?” The good news is—there are several clever ways to find out.

How to Find Your Ring Size at Home

If you're shopping for yourself and don’t have a ring sizer handy, here are a few reliable methods:

1. Use a Ring You Already Own

Take a ring that fits comfortably on the desired finger and:

Measure its inner diameter using a ruler (in millimeters).
Compare it with a standard ring size chart.

2. Try the String or Paper Strip Method

Wrap a thin strip of paper or string around the base of your finger.
Mark the point where it overlaps.
Measure the length in millimeters and compare it to a sizing chart to find your ring size.

Tip: Measure your finger at the end of the day when it’s at its largest. Avoid doing this in cold temperatures, as fingers shrink slightly in the cold.

3. Use a Printable Ring Sizing Guide

Download and print a ring size guide from a trusted jeweler like KRK Jewels. Make sure it’s printed to scale. You can either match an existing ring to the size circles or use the printable ruler to measure your finger.

How to Find Someone Else’s Ring Size Without Asking

Planning a surprise proposal or gift? Here are some subtle strategies to discover their size:

1. Borrow One of Their Rings

Secretly borrow a ring they wear on the correct finger (usually the left ring finger for engagements). Then:

Trace the inside and outside of the ring on a piece of paper.
Take it to a jeweler or measure the inner diameter yourself.
Make sure the ring you borrow is worn on the same hand and finger you’re shopping for.

2. Compare to Your Own Fingers

If they won’t notice a ring is missing, try it on one of your own fingers and mark where it stops. A jeweler can estimate their size based on how it fits you.

3. Ask a Friend or Family Member

A sibling or close friend might already know the size—or they could casually bring it up in conversation without raising suspicion.

4. Use a Soap or Clay Impression

If borrowing the ring isn’t possible for long, press it gently into a bar of soap or soft clay to create an impression. This can be used to estimate size with surprising accuracy.

5. Guess Based on Average Sizes (With Room for Adjustment)

If all else fails, you can make an educated guess based on average ring sizes:

Most women wear between a size 5 and 7.
Most men wear between a size 9 and 11.

When in doubt, go slightly larger, as it’s generally easier for a jeweler to size down a ring than to enlarge it—especially for intricate designs.
