Find your ring size in 2 minutes
Measure with a ring, with your finger or with a paper strip. Your size updates on the right — when it looks right, tap Use this size and we'll select it on your ring.
📏 Calibrate your screen not calibrated — sizes on screen are approximate
Pick something you have at hand, rest it on the screen without pressing and move the slider until the drawing is exactly its size: no gold edge should show around it and your object shouldn't stick out. We'll remember it on this device.
💡 Look at the screen straight on, not at an angle, with the browser zoom at 100 %.
Put the ring on the circle
Use a ring that fits the finger you're buying for. We always measure the inside: the thickness of the metal doesn't count.
- Calibrate once with a card or a coin (above) so the circle is true to size.
- Lay your ring flat on the circle, centred on the arrow, with the screen at full brightness.
- Move the slider until the gold line sits exactly on the inside edge: if you see it inside the hole, go bigger; if it hides under the metal, go smaller.
Rest your finger between the lines
Handy when you don't have a ring at hand. Fingers aren't perfectly round, so treat it as a guide and compare it with the paper strip if you can.
- Lay your finger flat on the screen, between the two lines, with its base (where the ring sits) level with the arrow.
- Move the slider until each line just touches the edge of your finger, without pressing the skin.
- Look from straight above. If your knuckle is wider, measure there too and keep the larger size.
Measure with a paper strip
You need a paper strip about 10 cm long and 1 cm wide (or non-stretchy string) and a pen. No ruler? Measure it on the real-size ruler below.
- Wrap the strip flat around the base of the finger, without twisting it — snug, but not pinching the skin.
- Mark with the pen the exact point where the strip overlaps. First check it would still slide over your knuckle.
- Measure: lay the strip on the ruler below with its start on 0 and tap (or drag) to your mark. You can also type the millimetres.
On a phone, turn the screen sideways or slide the ruler.
