Find your perfect fit
Each Bone & Wood ring is handmade and designed to feel just right. To help you find your ideal size, here’s a simple guide using everyday materials or Jason’s sizing tools.
All rings are sized using the UK/AUS ring sizing system. Jason uses a metal mandrel and ring sizer (shown in the reference images) to ensure each ring is measured with accuracy and consistency.
How to find your size
- Use a Jeweller’s Sizing Tool
Visit your local jeweller and ask for your UK/AUS ring size using a ring sizer or mandrel (not US sizes).
- Meet with Jason at the Bone & Wood Stall at Manly Markets
If you’re local, you can try on Jason’s exact sizing rings at the Manly Markets.
- Already Own a Ring That Fits?
Bring it along, or ask a jeweller to measure its size on a mandrel. Let Jason know the letter size (e.g. P, Q½, etc).
Measuring at Home
Circumference Method (Finger)
You’ll need:
- A strip of paper (5mm wide)
- A pen or pencil
- A ruler
Wrap the strip around the base of your finger, mark where the ends meet, and measure in millimetres. This gives your finger’s circumference.
Diameter Method (Existing Ring)
You’ll need:
- A ring that fits well
- A ruler
Lay the ring flat and measure the inside edge to edge. If it’s not perfectly round, use the shortest distance.
Helpful Tips
- If you’re between sizes, size up—especially for wide bands or stacking.
- Finger size can vary throughout the day depending on warmth and hydration. Measure a few times for accuracy.
- For wide bands, going up half a size often helps.
Buying a Gift?
To keep it a surprise:
- Measure a ring they already wear.
- Use a string or paper strip while they sleep.
- Ask a friend or family member who might know their size.
