Printable ring sizer
Print it at actual size: circles for a ring you own and a strip to wrap around your finger. Check the scale with the 50 mm line or a bank card.
- Print at 'Actual size' / '100%' (not 'Fit to page').
- Check the 50 mm line with a ruler, or lay a bank card on its outline.
- Have a ring? Lay it on the circles. No ring? Cut out the strip, wrap it round your finger and read the size at the end.
Circles: the inner diameter of a ring
Strip: wrap it round your finger
Cut out the strip, wrap it round the base of your finger so the 0 line meets the scale, and read where it meets: top row – US ring size, bottom row – circumference in mm. Between two sizes, take the larger.
How to use it
- Circles: lay your ring on the sheet and find the circle whose line just shows inside the ring.
- Strip: wrap it where the ring will sit, snug but loose enough to slide over the knuckle.
- For wide bands (6 mm and up) add half a size.

Frequently asked
01How do I know it printed at the right size?
Measure the 50 mm line with a ruler and lay a bank card on its outline. If they don't match, print again at 'Actual size' / '100%', not 'Fit to page'.
02What if I'm between two sizes?
Take the larger – especially for wide bands (6 mm and up) or if your knuckle is bigger than the base of the finger.
03Which is more accurate – circles or the strip?
If you have a ring that fits, the circles are the most accurate: lay it on and pick the circle whose line just shows inside the ring. Use the strip when you don't have a ring.
04Why measure in the evening?
Fingers swell a little during the day and shrink in the cold. Measuring in the evening at room temperature gives a size that fits all day.
