How to find your partners ring size
Guess it (not as crazy as it sounds):
- Fingers are proportionate to body type so, If your partner is petite, it’s likely that their hands are smaller and slender, start at a size H or I for women, and around an N for men.
- If they’re more average in height, chances are they have an average finger size too. An average finger size is L½ for women and Q for men.
- If your partner is above average height or build, start at around a ring size N for a woman and a size T for men.
- Take a ring they already wear to a jewellers for it to be sized.
- Bear in mind that the engagement/wedding ring finger is the third finger on the left hand
Use your own finger:
- This is our favourite, slide a ring that they already wear onto your own 'ring finger' and mark with a pen where it gets stuck. Take it to a jeweller and you'll get a very close size.

Helpful Ring Sizing Tips:
- Don't worry about taking a risk to make sure your occassion goes to plan. It's about the gesture and the way you propose that counts. I'ts thought in the industry that around 40% of all engagement rings are resized. You can get in touch with James Porter to help with resizing.
- Fingers expand and contract depending on the temperature. It might sound silly but bear that in mind if you're measuring a finger after walking into a jewellers after being out in the cold.
- If your knuckle is much larger than your finger’s base, take two separate measurements of both and choose a size in between. A ring should slide over the knuckly but not be too loose to slider around the finger.
- If you don't have a printer, you can use string or floss to wrap around a ring finger and mark it with a pet to get a length which you can then measure with a ruler. Bear in mind with this that string can stretch!
