How to Find Your Ring Size at Home in 2 Minutes

TL;DR
To find your ring size at home, wrap a strip of paper or string around your finger, mark where it overlaps, and measure that length in millimetres — that's your circumference. Indian ring sizes are numbers (roughly 6 to 26) based on this circumference. Measure at the end of the day and size up slightly for wide bands.
Method 1: the paper or string trick
- •Cut a thin strip of paper (or use a piece of string) about 10 cm long.
- •Wrap it snugly around the base of the finger you'll wear the ring on — comfortable, not tight.
- •Mark the spot where the strip overlaps with a pen.
- •Lay it flat against a ruler and measure the length up to the mark, in millimetres. That number is your finger's circumference.
- •Want the diameter instead? Divide the circumference by 3.14.
Method 2: measure a ring you already own
If you have a ring that already fits the right finger, this is the most reliable method. Lay it flat and measure the inner diameter — straight across the inside, edge to edge — in millimetres.
You can multiply that diameter by 3.14 to get the circumference, which is what Indian ring sizing is based on.
Understanding Indian ring sizes
In India, ring sizes are given as numbers — roughly from size 6 up to size 26 — and they're based on the inside circumference of the ring in millimetres. As a rough rule of thumb, the size number increases as the circumference grows, so a larger finger means a higher number.
These are approximate. Different makers round slightly differently, so treat your measurement as a guide rather than an exact science. If your circumference lands between two numbers, it's usually safer to round up.
Tips for the perfect fit
- •Measure at the end of the day — fingers are at their largest then, and you don't want a ring that only fits in the morning.
- •Avoid measuring when your hands are cold; cold fingers shrink and you'll size too small.
- •Size up slightly for wide or chunky bands — they sit tighter than thin ones.
- •Your dominant hand is often a touch larger, so measure the exact finger you'll wear it on.
- •If you're between sizes, round up — a ring that's a hair loose beats one that won't go on.

Frequently Asked Questions
How can I measure my ring size at home without a ring sizer?
Wrap a strip of paper or string around the base of your finger, mark where it overlaps, and measure that length in millimetres — that's your circumference. Divide by 3.14 to get the diameter if you need it.
How do Indian ring sizes work?
Indian ring sizes are numbers, roughly from 6 to 26, based on the inside circumference of the ring in millimetres. A larger finger circumference corresponds to a higher size number. Treat the numbers as approximate, as makers round slightly differently.
What time of day is best to measure ring size?
Measure at the end of the day when your fingers are at their largest, and avoid measuring when your hands are cold. This helps you avoid choosing a size that's too small.
What if I'm between two ring sizes?
Round up to the larger size — a slightly loose ring is more comfortable than one that won't fit. Wider bands fit tighter, so size up for those too, and contact our support team if you're unsure.
