# Crystal Bracelet Size Guide: How to Measure Your Wrist (UK) **By Cristian Maxim** · 2026-06-08 Getting the size right is the difference between a bracelet you wear every day and one that sits in a drawer. The good news: you only need a strip of paper or a piece of string and one minute. This guide shows you how to measure, gives you a clear cm and inch chart, and explains how a stretch bracelet should actually fit. ## Crystal bracelet sizing in 30 seconds Measure your wrist, then add about 1 cm for a comfortable fit on a beaded stretch bracelet. If you are between sizes or like a looser feel, size up. Most adults land between 17 cm and 19 cm, which is roughly a 7 inch to 7.5 inch bracelet. ## How to measure your wrist You do not need a jeweller. A strip of paper, some string or a soft tape measure is all it takes. Measure your wrist in 3 steps1Wrap a string snuglyaround your wrist2Mark where thestring overlaps3Measure the lengthin centimetres Measure where you would wear the bracelet, keeping the string snug but not tight. That number is your wrist size. For a beaded stretch bracelet, add about 1 cm for a comfortable fit, or a little more if you prefer it loose. ## Crystal bracelet size chart Find your wrist measurement, then read across to your suggested bracelet size. Sizes include a comfortable allowance, so you do not need to add anything to the chart.

If you have to force it over your knuckles it is too small, and if it slips off easily it is too big.

Larger beads take up more room around the wrist, so a 10 mm bracelet can feel a touch snugger than a 6 mm one of the same length. As a rule, if you like bold 8 mm to 10 mm beads and you are between sizes, choose the larger length. - **6 mm:** dainty and light, good for layering and smaller wrists. - **8 mm:** the classic everyday size, suits most wrists. - **10 mm:** bold and chunky, a statement piece. ## Buying a bracelet as a gift If you cannot measure the wrist, a medium (around 18 cm or 7 to 7.5 inch) fits most adults. Stretch bracelets are forgiving, which makes them one of the safest jewellery gifts. If you are still unsure, a gift set or a necklace avoids sizing altogether. ### Shop crystal bracelets at Crystals Healing UK Beaded stretch bracelets in a range of sizes and stones.

Most adults wear around 18 cm, which is roughly a 7 to 7.5 inch bracelet. This is the safest choice when buying as a gift. ### How much room should a stretch bracelet have? Aim for your wrist measurement plus about 1 cm. It should pass over your hand without forcing and sit with a little movement. ### How do I measure my wrist without a tape measure? Wrap a strip of paper or string around your wrist, mark where it overlaps, then measure that length against a ruler in centimetres. ### Should I size up for bigger beads? If you like 8 mm or 10 mm beads and you are between sizes, choose the longer length, as larger beads take up a little more room. ### Can a stretch bracelet be resized? Stretch bracelets are not easily resized at home without risking the cord. It is best to choose the right length, or contact us before ordering if you are unsure. ### Related reading - [How to clean crystal jewellery](/blogs/crystals-tips/how-to-cleanse-crystal-jewellery-safely-bracelets-necklaces) - [Water safe crystals](/blogs/crystals-tips/water-safe-crystals-what-can-go-in-water-and-what-to-avoid) _Our products are sold as decorative jewellery, gifts and home accessories.
