Every ring we make is made in the size you order, so getting the size right before you order saves everybody time. The most reliable way is to use a physical sizer on the actual finger, and we post one out for $10.
Here is how to work out your size, what our sizes mean, and what happens if it still turns out wrong.
Order a ring sizer: $10, posted to you
Our ring sizer is $10 with free shipping. It is a simple adjustable band you wear for a day, and it is the closest thing to trying on the real ring.
It is worth the $10 and the wait. A sizer costs a fraction of the inconvenience of posting a finished ring back across the country and waiting again while it is altered.
Once you know your size, order the ring in that size. If the design you want is offered in Small, Medium and Large rather than letters, check the letter shown beside each option, or ask us.
If you already have a ring that fits
Measure the inside diameter across the middle of the band, in millimetres, and match it to the chart below. Be as precise as you can, because half a millimetre is roughly a full size.
Two things to watch. Measure a ring that fits the same finger you are buying for, since fingers on the same hand differ. And if the ring you are measuring is much wider or much narrower than the one you are ordering, the fit will not be identical. See the note on band width further down.
If you would rather we did it, post the ring to us or bring it in and we will measure it properly.
Getting sized by a jeweller
Any jeweller will size you, usually for nothing. When you do, ask for two things:
- The size in Australian letter sizing, which is what we work in
- The inside diameter in millimetres of the sizer they used
The second one matters. Sizing sets vary slightly between makers, and a diameter in millimetres is unambiguous where a letter occasionally is not. Send us both and we can be certain.
Size conversion chart
We work in Australian letter sizes, which are the same as UK sizes. If you know your size in US numbers, this is the equivalent.

Conversions between sizing systems are approximate, and different charts round differently by as much as a quarter size. If you are ordering from overseas and working from a US size, tell us the millimetre diameter as well if you possibly can.
What Small, Medium and Large mean on our pieces
Some of our designs, mostly the silver signets, are offered as Small, Medium and Large rather than in the full letter range. Where that is the case, the letter equivalent is shown beside the option in the dropdown, because Small on one design is not always the same size as Small on another.
If a piece you are looking at offers Small, Medium and Large without a letter beside them, email us and we will tell you exactly what they are before you order. Please do not assume.
Buying it as a surprise
If you are buying for someone else and cannot ask, choose "Not sure" at checkout where the design offers it, and one of our consultants will get in touch to work through it with you.
The reliable ones: borrow a ring she already wears on the right finger and let us measure it, or ask someone whose judgement you trust and who can ask casually. Guessing from a photograph does not work, and neither does string around your own finger.
If you would rather not risk it at all, we can make the ring in the most likely size and resize it once you have proposed. Free within 60 days.
If the size is wrong
Resizing is free within 60 days of purchase. After that it is $110. Most designs move up to three sizes in either direction, and where a design cannot (eternity bands and some set designs are genuinely difficult), we will tell you what your options are rather than leave you with something unwearable. Resizing usually takes one to two weeks.
Two exceptions worth knowing before you order. Pieces made to a custom measurement rather than one of our standard sizes are final sale. And if another jeweller resizes one of our rings, that voids the warranty, so please come back to us.
Our warranty and repairs page has the full detail.
Things that change how a ring fits
Fingers are not a fixed size, which is why sizing is judgement as much as measurement.
- Temperature. Fingers swell in heat and shrink in cold, and the difference can be a full size. Measure at a normal room temperature, not straight after a shower or a walk in winter.
- Time of day. Fingers are usually smallest in the morning and largest in the late afternoon and evening. Late in the day is the safer time to measure.
- Knuckles. If your knuckle is noticeably larger than the base of your finger, size so the ring passes the knuckle with a little effort. It should resist slightly coming off.
- Band width. A wide band fits more tightly than a narrow one at the same size. For anything above about 6mm wide, going up a half size is usually right.
- Which hand. Your dominant hand is often a little larger. Size for the finger the ring will actually live on.
A well-fitted ring should slide on with light resistance and need a small tug to come off. If it spins freely it is too big, and a ring that is too big is far easier to lose than one slightly too small.
Still not sure?
Ask before you order. Email info@whitenovember.com.au and we will help you get it right, or order a ring sizer and measure at home.
