Ring size guide
How to measure your ring size
Two ways to find your size at home, with what you already have: a strip of paper or a ring that fits you.
Before you measure
Four things that change the result
-
01
Measure at the end of the day
Fingers swell as the hours pass. A measurement taken in the morning tends to feel tight by the afternoon.
-
02
Not when cold, not straight after exercise
Cold shrinks the finger and heat expands it. Pick a calm moment at a normal temperature.
-
03
The ring has to clear the knuckle
If your knuckle is wider than the base of the finger, measure the knuckle: the ring will sit a little loose below, but you will be able to put it on and take it off.
-
04
A wide band feels tighter
At the same size, a wide band sits more snugly than a thin one. On wide bands it is worth going up a number.
How to measure
Two methods, both with a ruler
With a strip of paper
- 01
Cut a strip of paper one centimetre wide.
- 02
Wrap it around the base of the finger, snug but not tight, and mark with a pencil the exact point where it crosses.
- 03
Unroll the strip and measure the millimetres up to the mark. That is the circumference of your finger.
- 04
Subtract 40. The number left is your Chilean size.
For example: 54 mm of circumference minus 40 is a size 14, which on the US scale is a 7.
With a ring you already wear
- 01
Pick a ring that fits well on the finger where you plan to wear the new one.
- 02
Rest it on a ruler and measure the inner diameter in millimetres, from inner edge to inner edge, across the widest point.
- 03
Look that diameter up in the table below.
Measure the inside, not the outside: the metal is one or two millimetres thick and that alone changes the size.

Chilean size, diameter and US size
Every piece in the catalogue publishes its Chilean size, its US size and its inner diameter, so you can check your measurement against any of the three.
| Chile size | Inner diameter | Circumference | US size |
|---|---|---|---|
| 8 | 15.3 mm | 48 mm | 4.5 |
| 9 | 15.6 mm | 49 mm | 5 |
| 10 | 15.9 mm | 50 mm | 5.5 |
| 11 | 16.2 mm | 51 mm | 5.5 |
| 12 | 16.6 mm | 52 mm | 6 |
| 13 | 16.9 mm | 53 mm | 6.5 |
| 14 | 17.2 mm | 54 mm | 7 |
| 15 | 17.5 mm | 55 mm | 7.5 |
| 16 | 17.8 mm | 56 mm | 7.5 |
| 17 | 18.1 mm | 57 mm | 8 |
| 18 | 18.5 mm | 58 mm | 8.5 |
| 19 | 18.8 mm | 59 mm | 9 |
| 20 | 19.1 mm | 60 mm | 9 |
| 21 | 19.4 mm | 61 mm | 9.5 |
| 22 | 19.7 mm | 62 mm | 10 |
| 23 | 20.1 mm | 63 mm | 10.5 |
| 24 | 20.4 mm | 64 mm | 11 |
If your measurement falls outside the table, the rule still holds: the Chilean size is the inner circumference in millimetres minus 40.
Between two sizes?
Take the larger one. A slightly loose ring can be worn; one that will not clear the knuckle cannot. And on a wide band, all the more so.

Why it pays to measure before you buy
For now the workshop does not resize a finished piece or make to order: each ring exists in the size it was made in, and only in that one.
Purchases are completed on Mercado Libre, so any exchange or return follows the terms of that platform.
