How to Measure Your Ring Size at Home (UK Sizes)

Ring sizing is the thing people fret about most before they order — and honestly, it needn't be. I've sized hundreds of fingers without ever meeting their owners, and there are a few easy ways to get it right from your own kitchen table. No special kit required (though one cheap gadget helps).

Slim stacker rings are an easy place to start.

Let me walk you through it.

First things first: use UK sizing

This is the big one. UK ring sizes run as letters — roughly E at the small end up to Z and beyond. The US uses numbers, Europe uses millimetres, and the three systems don't line up neatly. If you give me a US 7 when you meant a UK N, we'll both end up confused.

So wherever you can, work in UK letter sizes. It saves a lot of back-and-forth.

Method 1: measure a ring you already own

This is my favourite, because it uses a ring that already fits the right finger.

1. Find a ring you wear on the finger you're buying for.
2. Measure the inside diameter in millimetres — the gap across the middle, edge to edge.
3. Match that measurement to the UK ring size chart, which also shows US sizes and circumference in cm.

Be honest about which finger, though — your ring fingers and middle fingers can differ by a couple of sizes, and your dominant hand often runs slightly larger.

Measure the inside diameter — straight across the middle, edge to edge.

Method 2: a ring sizer (the cheap gadget)

If you don't have a ring to measure, a plastic ring sizer is the next best thing. In fact, I sell them here too — grab a UK A–Z ring sizer for £3 and I'll pop it in the post to you. It's a little belt of reusable plastic that you slide onto your finger and read off the size. Quick, cheap, and reusable for the next time.

Method 3: ask a jeweller

If there's a high-street jeweller near you, pop in and ask them nicely to measure your finger. Most are happy to do it, and it takes thirty seconds. Just remember to ask for the UK size.

A few things that quietly throw measurements off

Fingers are not fixed objects, annoyingly. A few things to keep in mind:

• Temperature. Cold fingers shrink, warm fingers swell. Measure when your hands are at a normal room temperature, not first thing on a frosty morning.
• Time of day. Fingers are often a touch larger in the evening and in hot weather. If you can, measure a couple of times across a day.
• Knuckles. If you've got knuckles bigger than the base of your finger, size up enough that the ring slides over the knuckle — but not so much that it spins.
• Band width. Wide bands sit more snugly than thin ones. If you're choosing a chunky style, you may want to nudge up half a size.

What if it still doesn't fit?

Then we sort it out — that's the whole point of buying handmade. I can resize most rings; just get in touch and I'll send you the address to post it to. Resizing usually takes about 10 working days from when it reaches me. If you ordered the wrong size there's a small charge; if I made it wrong, I'll fix it free.

So please don't let sizing nerves stop you. Worst case, we tweak it.

Ready to find yours?

Once you've got your number (well, your letter), come and have a browse. My rings are all made to your size, by hand, in my Nottingham studio. If you're after something you can build up over time, the everyday stacker rings are made for mixing, layering and generally hoarding like a happy magpie.

Measure twice, order once — and if in doubt, just ask me.
