How to measure your finger size?

There are a couple of ways to measure your finger size or work out for your partner if you are planning to surprise her with a proposal.

Measure a Ring you already own

One of the easiest ways to measure you finger is to find a ring that you own that fits well on the desired finger you would like the new ring to fit on. Then place the ring on a ruler like this (pictured below). This will give us the internal ring diameter. I like to to place the start of the internal diameter at 10mm rather than 0 so that it is easier to line up correctly. This measurement started at 10mm and finished at 27.20mm which gives us a total internal diameter of 17.20mm. Use the chart provided to work out what finger size this corresponds to. This ring works out to be a finger size of N.

Measurement Example

A handy tip to note that your dominant hand is slightly larger than your other hand, this meaning if you are looking to surprise your partner with an engagement ring, and she is right handed and wears a ring on her right hand fourth finger, locating that size is a great indication for the left hand engagement ring finger (it is usually about ½ size smaller).

Ring Sizer Kits / Visit local jeweller for size

A ring sizer kit is also a great option and great to have available at home. You can locate these easily on Amazon and they are inexpensive. If you do not have a ring or ring sizer kit at home, you can also visit your local jeweller to size you up. They will have a ring mandrel and sizes available to try. Please keep in mind that every ring mandrel is slightly different so it is also good to get a measurement of your size on the ring stick to give your rings internal diameter.

Measure your Ring Size at home with the Paper test

Another useful way to measure your size is to cut a long strip of paper and wrap it around the finger you wish the ring to fit on. Wrap it around until it overlaps and mark with a pen where it meets. It should be not loose, but nice and firm around finger. Measure below the knuckle where a ring would sit. Once marked, lay it out flat on the ruler with the beginning of the paper starting at 0. The marked line gives you the length to make your ring. The ring sizer chart here details how to correspond the length to your size.

For example, the total length measured here is approximately 53mm, which equates to a finger size of J1/2.
