Measure your size
You don’t have to get it perfect the first time.
Every order includes complimentary resizing and a discreet ring adjuster to fine-tune the fit — even as your body naturally fluctuates.
The most accurate way to find your size is by measuring your finger directly.
Using a plastic ring sizer (belt-style):
- Insert the tip through the buckle to form a ring
- Place it on your finger and tighten until snug
- It should slide over your knuckle with slight resistance
- Read the size where the arrow points
Using a metal ring gauge (individual rings):
- Try different sizes on the intended finger
- The correct size slides on with slight resistance
- It should pass the knuckle without forcing
- It should not feel loose once in place
If you are between sizes, choose the slightly larger one.
Use a ring you already own
Measure the internal diameter — the straight distance across the inside of the ring.
Then match it to the closest value below:
- Size 3 → 14.1 mm (0.555 in) internal diameter
- Size 3.5 → 14.5 mm (0.571 in) internal diameter
- Size 4 → 14.9 mm (0.587 in) internal diameter
- Size 4.5 → 15.3 mm (0.602 in) internal diameter
- Size 5 → 15.7 mm (0.618 in) internal diameter
- Size 5.5 → 16.1 mm (0.634 in) internal diameter
- Size 6 → 16.5 mm (0.650 in) internal diameter
- Size 6.5 → 16.9 mm (0.665 in) internal diameter
- Size 7 → 17.3 mm (0.681 in) internal diameter
- Size 7.5 → 17.7 mm (0.697 in) internal diameter
- Size 8 → 18.1 mm (0.713 in) internal diameter
- Size 8.5 → 18.5 mm (0.728 in) internal diameter
- Size 9 → 18.9 mm (0.744 in) internal diameter
- Size 9.5 → 19.4 mm (0.764 in) internal diameter
- Size 10 → 19.8 mm (0.780 in) internal diameter
- Size 10.5 → 20.2 mm (0.795 in) internal diameter
- Size 11 → 20.6 mm (0.811 in) internal diameter
- Size 11.5 → 21.0 mm (0.827 in) internal diameter
- Size 12 → 21.4 mm (0.843 in) internal diameter
- Size 12.5 → 21.8 mm (0.858 in) internal diameter
- Size 13 → 22.2 mm (0.874 in) internal diameter
Use the closest match — slight differences are normal.
Fit rules that actually matter
A correct fit:
- Slides on with slight resistance
- Passes the knuckle without force
- Does not fall off when your hand is relaxed
Quick check:
- Falls off easily → too big
- Gets stuck → too small
Band width changes your size:
- Wider bands feel tighter than thin bands
- A wide ring reaches the thicker part of your finger
- This often requires going up in size
Also consider placement:
- Lower on the finger → smaller size
- Closer to the knuckle → larger size
If stacking or choosing a wide band, sizing up slightly is usually correct.
Get sized by a jeweler
You can also visit a local jeweler and ask for a professional ring sizing.
- Most jewelers offer this service quickly and at no cost
- Ask them to measure the exact finger where the ring will be worn
- If possible, try a band with a similar width to the one you’re purchasing
This is a reliable option if you want a second confirmation.
What affects your size
- Fingers are larger at the end of the day
- Heat expands, cold contracts
- Your dominant hand is slightly larger
Measure at room temperature, at the end of the day, once or twice — that’s enough.
If it’s not perfect
We offer complimentary resizing for engagement rings within the first year.
- One free adjustment included
- Designed to refine the fit after real wear
Resizing by other jewelers may affect your warranty.
Your ring adapts with you
- A ring adjuster (clear insert) is included with your order
- Fits discreetly inside the band to make it slightly tighter
- Ideal for temporary size changes due to body fluctuations
If you’re unsure, choose your best estimate.
