HOW TO MEASURE YOUR RING SIZE AT HOME
The most reliable way to find your ring size is by visiting a local jeweller and asking them to size the finger you’ll be wearing it on.
But if you’d rather sort it yourself, we’ve made it easy. Below are a few at-home methods you can try to measure your ring size accurately.
Not in a rush? Request a free ring sizer and we’ll send it out — just allow 7–14 business days.
Already placed an order? Every Billie Jo ring ships with a free sizer. If the fit’s not right, use our returns portal within 30 days to exchange for the correct size.
At home Option 1:
Measure a Ring
- Grab a ring that fits the finger you’ll wear it on.
- Use a ruler or tape with millimetre (mm) markings.
- Place it flat and measure the inside diameter.
- Note down the size in mm
- Match it to the right size using our Ring sizing Chart.
At home Option 2:
Measure your Finger at home
- Cut a piece of string or paper — about 10cm long will do.
- Wrap it around your finger where the ring will sit. Make sure it feels snug, but not tight.
- Mark where the ends meet with a pen.
- Lay it flat against a ruler and measure the length in millimetres (mm).
- That number is your finger's circumference. Head to our Ring Size Chart to find your perfect US/Billie Jo size

Top Tips From Yours Truly
These tips come in handy when using our at-home ring size guide or printable sizer.
- Your finger size can shift during the day or with temp changes — measure in the afternoon when your hands are warm.
- Between two sizes? Go for the larger one — comfort’s king.
- Measure the finger you’ll actually wear it on — your hands can differ by up to half a size.
- Bulky knuckles? A bit of moisturiser helps rings slide on and off smoothly.
- Not 100% sure? Flick us an email — we’re always down to help.
- Bonus tip for the DIY crew: if your ring’s a bit too big, coat the inside with clear nail polish. Let it dry between layers — you can build up close to a full size if needed.
