Ring Size Guide

You’ve decided to pop the question and take the first step to spending the rest of your life together. We have some invaluable advice for choosing that special ring – even if you’re planning a surprise proposal.

The basics

Let’s start with the basics: The engagement ring sits on the third finger (next to the little finger) of the left hand.

If you come in with your partner for a consultation, we will measure your ring finger with a ring sizer. However, if you can’t make it to a physical consultation or would like to maintain the element of surprise, you can download our printable ring sizer. Our printable ring sizer is designed so that you can measure you or your partner’s rings in the comfort of your own home, it works by measuring the inner diameter of an existing ring.

The average women’s ring size is L½ and the average men’s ring size is Q

Guessing your partner’s ring size correctly can be done with a little common sense.

If you have a petite partner, it’s likely that their hands are smaller with slender fingers, so try starting at a size H or I for women, and around an N for men.

If they’re closer to an average height, chances are they have an average finger size to match. An average finger size is L½ for women and a Q for men.

Finally, if your partner is above average height or build, their weight will be naturally distributed across their whole body, so it might be a good idea to start at around a ring size M or N for a woman and a size T for men.

How do you find out your partner’s ring size without them knowing?

If asking out-right isn’t an option, you could ask your partner’s family and friends for help because they may be able to offer their advice. You could even ask her or his  friends to suggest going out to try on rings and have their finger size measured while there.

There are other options like having a ring they already wear on her left-hand ring finger discreetly measured. However, if the ring is wider or narrower than 2mm, the more likely it is that the ring size won’t be entirely accurate, but it will be a rough indication.

Resizing rings

It’s worth noting that a round 40% of rings end up being resized , so as long as you can get a rough estimate by following these basic ring size guidelines, you’ll get a pretty close idea. If you don’t measure the correct size the first time, not to worry.

What does it cost to get a ring resized?

If you don’t manage to find the right ring size, we offer a complimentary first re-size on most Taylor & Hart designs to make things nice and simple.

Can all rings be resized?

Unfortunately not. If the ring needs to be resized any more than two sizes larger or smaller, there may be a fee that you must pay as your ring may have to be re-made.

Also, some designs are unable to be resized, for example, full eternity rings or twisted bands. In this case, product pages will specify if they are unable to be resized and for bespoke designs, your design consultant will notify you if your design is unable to be resized.

Does resizing a ring weaken it?

In cases where the ring is being resized one or two sizes up or down, no.

Resizing is commonplace at our workshop. To resize your ring, we make a small incision in the band and extend or tighten it as required. Once that’s completed, the gap is soldered and polished to seamlessly hide any evidence of alterations.

When a ring needs to be resized any more than two sizes larger or smaller, there may be a fee that you must pay as your ring may have to be re-made to ensure its durability.
