Ring Sizing Guide

Getting the right size matters - especially when your ring is made-to-order just for you.

Ugli Pup uses Australian (AU) standard sizing, in letter format. Here's a guide on how to measure at home.

A friendly reminder: This guide is here to help, but it's a DIY method. For the most accurate measurement, we recommend visiting your local jeweller.

Method 1: Measure a ring you already own

If you already have a ring that fits the finger you're buying for, this is the most accurate option:

  • Place the ring on a flat surface.
  • Measure the inside diameter (edge to edge, straight across) in millimetres.
  • Match that measurement to the size chart below.
  • Important: measure the inside of the band, not the outside.

No ring? No problem.

Method 2: Measure your finger directly

What you'll need: a strip of paper or string, and a ruler.

  • Cut a piece of string or strip of paper approximately 10cm long and 0.5cm wide.
  • Wrap the strip snugly* around the finger you'll wear the ring on.
    *(Snug, not tight - we want comfort, not circulation issues.)
  • Mark where the strip overlaps.
  • Measure the length in millimetres.
  • Match that number to the size chart below.

Tip: If you're between sizes, size up - especially for wider or chunkier rings, which feel tighter than narrow bands.

Another method to consider

  • Use a ring sizer tool (these are widely available online).

Keep in mind

  • Fingers change size depending on temperature, time of day, and hydration. Measure when your hands are at a normal temperature (not freezing, not swollen).
  • It's recommended to measure at room temperature, preferably towards the end of the day.
  • Your dominant hand is usually slightly larger.
  • Wider bands and chunky rings feel tighter. When in doubt, size up.
  • If your knuckle is larger than the base of your finger, choose a size that comfortably passes over the knuckle.
  • Seasons, temperatures, body weight fluctuations, health, hydration, and even salt intake can affect your ring size.
  • Taking multiple measurements throughout the day and averaging them is a solid choice.
