How to Measure Your Ring Size at Home (3 Easy Methods)

GOLDÈRE Editorial·February 26, 2026·5 min read

Buying a ring online means getting the size right the first time. Whether you're shopping for yourself or ordering The Eclipse Ring as a gift, here are three reliable methods to measure ring size at home.

Method 1: The String/Paper Strip Method

This is the most popular at-home method and works well for most people.

What you need: A piece of string, dental floss, or a thin strip of paper. A ruler or measuring tape (in millimeters). A pen.

Steps:

Step 1: Wrap the string or paper strip snugly around the base of your finger. Not too tight, not too loose — you should be able to slide a thin piece of paper between the string and your skin.
Step 2: Mark where the string overlaps with a pen.
Step 3: Lay the string flat and measure the length from the end to your mark in millimeters.
Step 4: Use the chart below to find your size.

Ring Size Chart (US Sizes)

| Circumference (mm) | US Size | Inner Diameter (mm) | |---|---|---| | 44.2 | 3 | 14.1 | | 46.1 | 3.5 | 14.7 | | 48.0 | 4 | 15.3 | | 49.3 | 4.5 | 15.7 | | 50.6 | 5 | 16.1 | | 51.8 | 5.5 | 16.5 | | 52.5 | 6 | 16.9 | | 54.4 | 6.5 | 17.3 | | 55.7 | 7 | 17.7 | | 57.0 | 7.5 | 18.1 | | 58.3 | 8 | 18.5 | | 59.5 | 8.5 | 18.9 | | 60.8 | 9 | 19.4 |

The Eclipse Ring is available in US sizes 5-9.

Method 2: The Existing Ring Method

If you already own a ring that fits the correct finger, this is the easiest method.

What you need: A ring that fits well. A ruler (in millimeters).

Steps:

Step 1: Place the ring on a flat surface.
Step 2: Measure the inside diameter (the widest point across the inside of the ring) in millimeters.
Step 3: Match the diameter to the chart above.

Pro tip: Make sure the ring fits the same finger on the same hand. Your dominant hand is usually slightly larger, and ring sizes can vary between fingers by 1-2 full sizes.

Method 3: The Printable Ring Sizer

Many jewelry brands offer printable ring sizers — a strip of paper you print at 100% scale, cut out, and wrap around your finger like a belt.

Important: When printing, make sure "Actual Size" or "100%" is selected in your printer settings. Any scaling will throw off the measurement.

Tips for Getting an Accurate Measurement

Measure at the end of the day — fingers swell slightly throughout the day. Evening measurements are more reliable.
Measure at room temperature — cold shrinks fingers, heat expands them.
Measure 2-3 times — take the average if you get slightly different results.
Consider the knuckle — if your knuckle is significantly larger than the base of your finger, size up by 0.5. The ring needs to slide over the knuckle but sit snugly at the base.
Account for ring width — wider bands (5mm+) need a slightly larger size. For thin bands like The Eclipse Ring (2mm), your standard size is perfect.

Common Ring Sizing Mistakes

Measuring too tight — the string should be snug, not cutting into skin
Measuring when cold — your fingers are at their smallest
Measuring after exercise — fingers may be temporarily swollen
Using a ring from a different finger — each finger is different
Printing the sizer at wrong scale — always verify with a known measurement

What If You're Between Sizes?

If your measurement falls between two sizes, follow these guidelines:

For thin bands (1-3mm wide): Go with the smaller size — thin rings feel looser
For wide bands (4mm+): Go with the larger size — wide rings feel tighter
For comfort: When in doubt, size up by half a size. A slightly loose ring is more comfortable than a tight one

International Size Conversion

Frequently Asked Questions

What's the most common ring size for women? US sizes 6-7 are the most common for women. The Eclipse Ring covers sizes 5-9 to fit most hands.

Do ring sizes change? Yes. Weight fluctuations, pregnancy, temperature, and time of day all affect finger size. Measure when your hands feel "normal."

Can I resize a ring later? Solid metal rings can sometimes be resized. Gold-plated rings on surgical steel cannot be resized — which is why getting the right size upfront matters.
