Jewellery sizing

We are all unique and have our own preferences regarding good sizes of jewellery. This does make it difficult to make suitably fitting jewellery. That’s exactly why there are a few industry accepted standards for sizing rings and necklaces. See below some information and guidance tables which should help in identifying the right size of jewellery specifically for you.


This table shows UK sizes against the mm measured value of your finger. Best way to find out what that is, is to take a thin strip of paper (same/similar width to your desired ring) and wrap around the chosen destination finger and mark where the paper overlaps itself, then flatten out the paper and measure from the end to where your mark is. This is your ring size in metric mm, use the table below to get the closest standard size.

Note, our fingers do naturally change site during the day for many reasons (weather, what you’re eating, medical conditions etc.). So choose a time to measure according to your body.

This table shows generally accepted lengths of necklaces. To find your preferred size use a measuring tape or a piece of string, which you can measure afterwards and place around your neck joining the end together to the string/tape where you want it to sit. That measurement / length will be your custom length or you can match it to the guide size chart below.

Note, with any chain, depending on the size and make, it will rest against your body so add a cm for flexibility.

With bracelets the same measuring method applies, use a piece of string, measuring tape or paper to determine your desired size.

Allow yourself some room to move though by placing two fingers under the measuring tool. This will help by allowing for a bit of movement throughout your daily activities.


Now these are fairly difficult to measure as there are a lot of things to consider, including pierced ears or un-pierced, where the piercing sits on your ear, where the design is meant to sit, do you like dangles or studs, is the design flexible or one-size.

Considering a few of these points I’ve laid out a guide table below.
