How to Measure Your Ring Size at Home (No Tools Required!)

by Ankur Jalvi in Bush Telegraph

Buying a ring online but not sure of your size? No worries! Figuring out your ring size at home is easy. Whether you're treating yourself or shopping for someone else, this guide will help you find the perfect fit. We'll walk you through a few simple methods and include a handy ring size conversion chart for different countries.

Why Getting the Right Ring Size Matters

A ring should fit snugly but still slide over your knuckle without a struggle. Too loose, and it might slip off. Too tight, and it’ll be uncomfortable. Let’s make sure you get it right the first time!

Easy Ways to Measure Your Ring Size at Home

1. Use a Piece of String or Paper

This is the simplest method and only takes a minute:

Cut a strip of paper or grab a piece of string.
Wrap it around the base of your finger.
Mark where the ends meet.
Lay it flat and measure with a ruler (millimeters are best).
Compare your measurement to a ring size chart.

2. Measure an Existing Ring

Already own a ring that fits well? Use it to find your size:

Place the ring on a ruler and measure its inner diameter (straight across the center).
Match that measurement to a size chart.

3. Use a Printable Ring Sizer

Some online jewellers (including us at Sailors & Seekers) offer printable ring sizers. Just print it at 100% scale, place a ring over the circles, and find the closest match.

4. Buy a Ring Sizer - No Stop! We have one for free ;)

Pro Tips for Measuring Your Ring Size

Measure at the Right Time: Fingers swell slightly throughout the day. Measure in the evening for the most accurate size.
Consider Your Knuckle: If you have larger knuckles, go up half a size so the ring can slide on easily.
Check Multiple Times: Measuring twice (or thrice) helps avoid mistakes.
