Ring Size Guide

Finding your size should be the easy part. Use the chart below to find your fit, or let us do the work with a free ring sizer in every order.

Find your size

Reference this table to find your Miki ring size. We make our rings in full sizes only.

MiKi / US Australia / UK Inner diameter Circumference
5 J½ 15.7mm 49.3mm
6 L½ 16.5mm 51.9mm
7 N½ 17.3mm 54.4mm

10 T½ 19.8mm 62.1mm
11 V½ 20.6mm 64.6mm

MiKi rings come in whole US sizes. Australian sizes shown are the nearest match. Not every design comes in every size, so check the size options on each ring.

Measure a ring you already own

The most accurate way to find your size at home. Choose a ring that fits the finger you're buying for, measure straight across the inside from edge to edge in millimetres, then match it to the inner diameter column in the chart above.

Use string or paper

Wrap a thin strip of paper around the base of your finger so it's snug but comfortable. Mark where it overlaps, lay it flat and measure the length in millimetres, then match it to the circumference column in the chart above.

Wider bands fit snugger

A wide band covers more of your finger, so it feels tighter than a slim band in the same size. For any ring with a band 5mm or wider, we recommend going up one size.

This currently applies to the Mila Ring, the Coral Cove Gold and Coral Cove Silver Rings.

Toe rings

All our toe rings are adjustable. Gently open or close the band a little at a time until it sits comfortably. Avoid bending it back and forth repeatedly, as this can weaken the metal.

Your questions, answered

How do I find my ring size at home?

The easiest way is our free ring sizer, just tick the FREE Ring Sizer box on your cart page and it ships with your order. If you want a size right now, wrap a strip of paper snugly around the base of your finger, mark where it overlaps, measure the length in millimetres and match it to our size chart.

When should I measure my finger for a ring?

Fingers change more than you would think. They are at their largest at the end of a warm day and at their smallest on a cold morning, so measure in the evening, and if you are buying in winter, allow a whisper of extra room for summer. Measuring twice on different days is the closest thing to a guarantee. And size to your biggest knuckle if the ring needs to pass over one.

I am between ring sizes. Which do I choose?

Go up. A slightly loose ring spins, a slightly tight one pinches, and spinning is the better problem to have. For wider bands, definitely size up one full size, as they wear tighter than thin bands and we don't offer half sizes.

What if I order the wrong ring size?

Choose the wrong size? Send it back within 30 days of delivery and we will swap it for the right size, or pop the value on a store credit. Earrings and toe rings aren't eligible for change-of-mind returns for hygiene reasons, which is exactly why the free ring sizer exists, grab it before you order. If anything arrives faulty, that is different, contact us and we will make it right.

How do I fit an adjustable toe ring?

Slide it on, then gently squeeze the band once it is in place until it feels secure but not tight. Adjust it in small movements rather than one big bend.

Are MiKi rings in Australian or US sizes?

US sizes. Use the chart on this page to convert from Australian letter sizes.

Should I size up for wide rings?

Yes. For bands 5mm or wider, go up one size.

Is the ring sizer really free?

Yes. Just tick the box in your cart and we'll include one with your order.
