Buying a ring without knowing your size is the most common reason jewellery gets returned. It takes about two minutes to avoid, and you don't need anything you don't already own.

Method one: measure a ring you already own

This is the most reliable method, because you're measuring something you know fits.

1. Choose a ring that fits the finger you have in mind.
2. Place it flat on a table.
3. Measure straight across the inside, from inner edge to inner edge, in millimetres.
4. Match that measurement to the chart below.

Measure the inside of the band, not the outside. It's an easy mistake and it'll put you a size or two out.

Method two: measure your finger

Use this if you don't have a ring to hand.

1. Cut a thin strip of paper, or use a piece of string.
2. Wrap it around the base of your finger. Snug, not tight — it should sit as a ring would.
3. Mark where the ends overlap.
4. Lay it flat and measure to the mark in millimetres. That's your circumference.

One thing to check before you commit: the strip needs to slide over your knuckle. If your knuckle is noticeably wider than the base of your finger, measure the knuckle too and choose something between the two.

Getting an accurate measurement

Measure at the end of the day. Fingers swell slightly as the day goes on. An evening measurement reflects your finger at its largest, which is the size you want a ring to fit.

Avoid measuring when cold. Cold fingers shrink noticeably. A ring sized on a winter morning will feel loose by afternoon.

Measure the right hand. Most people's dominant hand is slightly larger. Measure the specific finger you'll wear the ring on.

Consider the band width. Wide bands fit more tightly than thin ones. If you're choosing a broad ring and you're between sizes, go up.

If you're between sizes

Go up. A ring that's slightly loose can be worn comfortably and won't cut in when your fingers swell in heat or after exercise. A ring that's slightly tight is uncomfortable, hard to remove, and often ends up unworn in a drawer.

Buying as a gift

If you can't ask directly, borrow a ring they already wear and measure it — checking which finger it's usually worn on, since it makes a difference.

If that's not possible, a bracelet or necklace is a safer gift. Neither needs sizing, and both are easier to get right.
