Follow these directions to measure your finger. They will give an approximate guide to establish your ring size. For a completely accurate measurement go to a jeweller and have your finger sized precisely.

Find a piece of string or strip of paper no wider than 1.4 cm (1/2 inch).

Wrap it around the base of the appropriate finger.

Use a pen to mark the point on the string/paper where it overlaps, forming a complete circle.

With a ruler, measure the length from the starting end of the string/paper to the pen mark.

Use the chart below to determine your UK ring size.

For the most accurate reading using this method measure the finger at the end of the day when the finger is the largest.

Here are some tips to make your ring size measurement more accurate:

After sliding the ring sizer on, make sure it slides off fairly easily over the knuckle.

What if your planning a surprise proposal?

Aside from the where, what, why and how of your surprise proposal, getting a ring to fit your intended's finger ahead of time can be a tricky prospect.

The following are a few tips for secretly obtaining your partner's ring size, gleaned from the collective knowledge of our experienced team here at Goldsmiths. Once you have discovered your partner's size, you will be better able to peruse our extensive collection of diamond solitaire and gem-set engagement rings in a full choice of precious metals.

The simplest way to find your partner's ring size is to 'borrow' a ring they already wear. As engagement and wedding rings are typically worn on the third finger of the left hand, it's perhaps unlikely that that finger is already adorned. Simply choose a ring usually worn on the middle finger instead, and be prepared to go down a size or two for the right fit.
