How to Measure Bangle Size at Home – 5 Easy Methods

The easiest way to measure your bangle size at home is to measure the inside diameter of a bangle that already fits you. No bangle? Measure around your folded hand with a thread, divide by 3.14 and pick the next size up. Or let the bangle size calculator do the maths, from a bangle on your screen, a photo of your bangle next to a coin, or your hand measurement.

What you are actually measuring

A rigid bangle has no clasp, so it has to slide over your hand. The size that matters is therefore not your wrist but the widest part of your folded hand: thumb tucked into the palm, fingers pressed together, the way you naturally squeeze your hand when putting on a bangle. Indian bangle sizes describe the inside diameter in inches and sixteenths (2.4 = 2 4/16 in = 57.2 mm), so every method below ends with a diameter.

Method 1: Measure a bangle you own (most accurate)

1. Pick a rigid bangle that goes on without soap but does not fall off.
2. Lay it flat on a ruler with mm markings.
3. Measure across the inside edge, through the centre. Turn it 90° and measure again; use the larger number.
4. Find the nearest size: 54 mm = 2.2, 57 mm = 2.4, 60 mm = 2.6, 63.5 mm = 2.8, 66.7 mm = 2.10.

Method 2: Thread or tape around your hand

1. Tuck your thumb into your palm and bring your fingers together.
2. Wrap a thread, ribbon, strip of paper or soft tape around the widest point – over the thumb knuckle and the base of the little finger.
3. Mark where it meets, lay it on a ruler, and note the length in cm.
4. Divide by 3.14 to get the diameter, then choose the first size that is at least that wide.

Example: a hand of 18.4 cm ÷ 3.14 = 5.86 cm. Size 2.4 is 5.72 cm (too small) and 2.6 is 6.03 cm, so your size is 2.6. You can skip the maths by using the hand-circumference column on the bangle size in cm chart.

Method 3: By hand width

Some guides say to measure the width of your hand across the knuckles. This is the least reliable method, because a hand is not round: it squeezes into an oval when you put on a bangle, so its flat width is larger than the bangle you need. If a ruler is all you have, measure across the knuckles with your thumb tucked in and fingers squeezed, then use the result only as a rough check. A folded hand width of about 7 cm usually corresponds to 2.4–2.6, and 8 cm to 2.8–2.10, but individual hands vary by a full size. Confirm with Method 2.

Method 4: On your phone screen

1. Open the online bangle sizer.
2. Calibrate once by matching a bank card to the outline (on a phone, hold the card upright and match its short side; on a computer, match its long side). No card? Tap No card? Use a coin and match a ₹10, Rs 10, quarter, 10p or €2 coin instead.
3. Place your bangle flat on the screen and move the slider until the circle meets the inside edge.
4. Read the size in Indian sizes, mm, cm and inches.

This is as accurate as a ruler and avoids misreading the scale. Most phone screens are about 65–70 mm wide, so bangles up to about 2.6 fit on them. For a 2.8 or larger bangle, use a tablet or laptop, or Method 5.

Method 5: From a photo (any bangle, any phone)

1. Lay the bangle flat on a plain table and put a coin right next to it: an Indian ₹10, Pakistani Rs 10, US quarter, UK 10p or €2 coin.
2. Hold your phone flat, straight above them, about 40 cm away, and take a photo. Do not tilt the phone: a tilted photo squashes circles into ovals.
3. In the bangle size calculator, tap From a photo, pick the coin you used and choose the photo.
4. Fit the gold circle to the outer edge of the coin, then the blue circle to the inside edge of the bangle. Zoom in for a precise fit.

The coin has a known size, so it tells the tool how many pixels make a millimetre in your photo. No card calibration is needed and the bangle can be any size. Expect about ±1 mm, which is still within one bangle size. The photo is only shown in your browser and is never uploaded.

Prefer paper? Print a bangle sizer

Print the free printable bangle sizer at 100%, check the 50 mm line with a ruler, then lay your bangle on the true-size circles for sizes 1.10 to 3.4. The sheet also has a string scale for your hand, so you can skip the division by 3.14.

Common mistakes

• Measuring the wrist. Wrist size is for bracelets. A bangle must pass the hand, which is 3–5 cm larger.
• Measuring the outside of the bangle. Always the inside edge.
• Measuring with an open hand. Spread fingers add 1–2 cm; fold your hand as when wearing.
• Rounding down. Between two sizes, a rigid bangle must be the larger one.
• Photo from an angle, or coin on a different surface. Keep the phone flat above the bangle and the coin on the same table, right next to it.
• Measuring when cold. Hands are smaller in the morning and in winter; measure in the evening at room temperature.

Sources and standards

• Indian bangle size convention: sizes are inner diameter in inches and sixteenths (2.4 = 2 4/16 in). It is a trade convention, not a published standard, so makers can differ by about 1 mm.
• NIST – SI units: length: 1 inch = 25.4 mm exactly, used for every inch-to-mm conversion.
