Getting this right
matters.
Everything you need to get the perfect fit — before you order.
Borrow one of
her existing rings.
If you're keeping the proposal a surprise, the most reliable approach is to bring one of her existing rings to a jeweller.
A few things to confirm first:
- Make sure it's a ring she wears on her ring finger — not another finger
- Tell the jeweller which hand she wears it on
- Note that the dominant hand is usually about half a size larger than the non-dominant hand
This information helps the jeweller size it correctly.
Even with a reference ring, an experienced jeweller can give you a confident estimate — and our Perfect Fit Guarantee covers one free resize within 12 months.

When in doubt, size slightly larger.
Jewellers generally recommend sizing up rather than down. It's easier to resize a slightly loose ring than one that's too tight to remove.
Visit a local
jeweller first.
An engagement ring is a meaningful and precise purchase. The best way to ensure it fits properly is to have it measured by a professional jeweller.
Ring size affects comfort, security, and how the ring feels day to day. Small differences can matter more than most people expect.
A jeweller will measure ring size using professional sizing tools and take into account factors like finger shape, knuckle size, and overall comfort. This removes guesswork and helps avoid resizing later.
For a ring of this importance, accuracy is worth it.

Why we don't recommend
DIY methods.
Online tools, printable charts, string, paper, and home measurements often lead to small errors. Fingers change size throughout the day, and many at-home methods don't account for the knuckle.
For an engagement ring, "close enough" usually isn't good enough.
"Close enough" usually isn't.
A ring that's even half a size off can feel noticeably tight or loose after a few hours of wear. The knuckle size, time of day, and temperature all affect fit in ways home measurements miss entirely.
If you're between
sizes.
When in doubt, jewellers generally recommend sizing slightly larger rather than smaller. It's easier to make small adjustments later than to force a ring that's too tight.
