Hammertone Copper Ring

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

1. 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).
2. 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. 
3. 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.
