How Do I Get My Girlfriend's Ring Size without Her Knowing?

It's a question that we at Abelini are commonly asked by people planning a marriage proposal. You might have ironed out all of the details of how and where you'll do it and found the perfect ring, but there's one big issue - making sure it actually fits.

There are various ways you can approach it. If your partner has a ring that fits the ring finger of their other hand, sneak a peek in their jewellery box and measure it when they're out or asleep. You could enlist the help of their friends - either to ask about sizing or to take them shopping and suggest trying on engagement rings as something fun to do.

Whichever method you choose, you'll not only want a ring that fits when you actually propose but one that you're sure will fit properly when they're wearing it day in, day out. Here's how.

How Should A Ring Fit A Woman?

You'll know that a ring is a perfect fit based both on the knuckle and the place where it sits.

A well-sized ring should slide over the knuckle with a little bit of friction - and there should be some resistance over the knuckle when you take it off.

When you're actually wearing the ring, it should sit snugly on your finger, but not so tightly that it leaves an indent or bulging skin. Remember, the size of our fingers does fluctuate, though, and they tend to be at their largest between lunch and dinner - bear this in mind when working out her ring size.

How Can You Know Your Ring Size?

The most accurate way of working out your ring size is to use a professional ring sizing tool. You can either buy one to use at home or go to a jeweller where they will be able to measure the ring size with greater accuracy.

Some people use other methods, such as measuring the diameter of a ring with a ruler or tracing around it on paper. This may not be as accurate as you'd want, though, for a piece of jewellery that is so meaningful, and that will be worn every single day.

What Is The Most Common Ring Size For A Woman?

In the UK, the most common engagement ring size for a woman is a size L, with M and N following closely behind.
