About the Bracelet Size Calculator
This bracelet size calculator converts a wrist measurement into the bracelet length to order, in inches and centimetres, along with the usual XS–XXL size. Choose how you like a bracelet to sit — snug, comfortable or loose — and how thick the bracelet is, and it adds the right amount of ease.
It is handy when buying jewellery online, making a beaded or charm bracelet, or choosing a gift when you can secretly measure a wrist with a strip of paper. For solid bangles, which must slide over the hand rather than fasten round the wrist, enter your hand measurement to get the minimum inner diameter and the matching “2-x” bangle size used by many jewellers.
Ease figures follow common jeweller guidance: about ½ inch for a snug fit, ¾ inch for comfort and 1 inch for a loose, dangling fit, with extra length for chunky or beaded styles because thick bracelets take up space inside the loop. Brands differ, so check the maker’s chart when one is given.

- 4For bangles, measure around your knuckles with the thumb tucked in.
- 5Order the bracelet length or bangle size shown.
Formula and method
A bracelet that fastens needs to be longer than the wrist so it can move. The calculator adds ½ inch for a snug fit, ¾ inch for a comfortable fit or 1 inch for a loose fit, then a further ¼ inch for beaded or medium bracelets and ½ inch for chunky ones, because thick links reduce the space inside the loop. Lengths are converted at 2.54 cm per inch.
A rigid bangle has to pass over the compressed hand, so its inner circumference must be at least the hand measurement taken around the knuckles with the thumb tucked in. Dividing by π gives the minimum inner diameter, which is rounded up to the next ⅛ inch — the steps used in “2-x” bangle sizing, where 2-8 means 2 8/16 = 2.5 inches.

Worked examples
6.5 inch wrist, comfortable thin chain
A 6.5 in wrist plus ¾ in comfort ease gives a 7.25 in (18.4 cm) bracelet — a medium. An 8 in hand needs a bangle at least 8 ÷ π = 2.55 in across, so size 2-10 (2.625 in) is the smallest that slips on.
15 cm wrist, snug beaded bracelet
Fifteen centimetres is 5.91 in. Adding ½ in for a snug fit and ¼ in for beads gives 6.66 in (16.9 cm), a small. A 19 cm hand needs at least a 2.38 in inner diameter, so a 2-8 (2.5 in) bangle.
7.25 inch wrist, loose chunky cuff-style chain
A 7.25 in wrist with 1 in loose ease and ½ in for chunky links needs an 8.75 in (22.2 cm) bracelet, an XXL. A 9 in hand needs at least 2.86 in across, so a 2-14 (2.875 in) bangle.
Frequently asked questions
How do I measure my wrist for a bracelet?+
Wrap a soft measuring tape, or a strip of paper you then lay against a ruler, around your wrist just below the wrist bone. Keep it snug but not tight, then add ease for the fit you want.
What is the average bracelet size?+
Most adult women wear a 7 to 7.5 inch bracelet (wrist about 6–6.5 in), and most men an 8 to 8.5 inch bracelet. A 7 inch bracelet is the most common stock length for women’s chains.
How much bigger than my wrist should a bracelet be?+
Add about ½ inch (1.3 cm) for a snug fit, ¾ inch (1.9 cm) for a comfortable fit and 1 inch (2.5 cm) for a loose fit. Wide or beaded bracelets need an extra ¼–½ inch.
How do I find my bangle size?+
Tuck your thumb into your palm and measure around the widest part of your knuckles. Divide by π (3.14) for the minimum inner diameter, then choose the next bangle size up so it slips over your hand.
What does bangle size 2-6 mean?+
In the common Indian bangle system, 2-6 means an inner diameter of 2 and 6/16 inches, or 2.375 in (about 60 mm). Each step of 2 adds ⅛ inch (about 3.2 mm).
