Your fingers can change size throughout the day (and the year). Body temperature, climate, even salt intake can affect how snug or loose a ring feels. Measure your finger in the evening at room temperature, when your body is relaxed.

Wider bands (3mm or more) will feel firmer on the finger and may require you to go up half a size or more.

We suggest going up in sizing for wide bands. Wider rings (≥3–5mm) fit tighter across the finger. For 5mm+ bands, consider sizing up ¼ size; for 7mm+, up to ½ size.

We offer one complimentary resize on all Black Finch rings and offer subsequent resizing services for a fee. 

If your resize requires a big jump (+2 sizes up or down), we may need to remake the ring to maintain its structural integrity.

Yes, you can accurately find your ring size at home by using methods like a ring sizer tool, measuring an existing ring, or the string/paper method, you can get a reliable size. Double-check across different times of day to account for finger fluctuations.

Use our ring size chart where K-N-Q correspond roughly to 51–68mm circumference. We include international conversions for clarity.

You can estimate based on a partner’s existing ring or ask a trusted friend.

Your finger size can change over time. Factors like weight, pregnancy, temperature, alcohol consumption or even a salty meal can affect your finger size. If your size fluctuates seasonally, you may wear the ring on a pendant chain temporarily.

There are a few simple ways to calculate your ring size at home. You can wrap a strip of paper or string snugly around the base of your finger, mark where it overlaps, then measure the length in millimetres and match it to a ring size chart. Or, if you already have a ring that fits well, you can measure its internal diameter and compare that to our guide. For the most accurate fit, especially for wider bands, we recommend using a physical ring sizer.

Yes, there are mobile apps that claim to help you find your ring size using your phone camera or screen. They can be a handy starting point, especially when measuring an existing ring. However, they’re not always perfectly accurate. For peace of mind (and a better fit), we suggest double-checking with a ring sizer or visiting our Melbourne studio. 

The best way to find your engagement ring size is to measure your finger at the end of the day, when it’s at its largest (fingers tend to shrink slightly in the cold). You can use a physical ring sizer, a printable chart, or measure the inside diameter of a ring that already fits that finger well. If the ring is a surprise, see if a friend or partner can discreetly borrow one of their rings, or we can help you choose a safe ‘average’ size with room to resize later if needed.

Your wedding ring should fit snugly but comfortably, firm enough that it won’t slide off, but loose enough to slide over your knuckle without force. Keep in mind that wider bands often feel tighter, so you may need to size up slightly for a perfect fit.
