3 most accurate ways to measure bracelet size
Method 1: Measure using an existing bracelet "Measure the diameter" (Method for rigid bracelets/bangle size)
Tools
- An existing bracelet/bangle that fits well
- A ruler (with millimeter - mm units)
How to do it
- Step 1: Place the existing bracelet on a flat surface.
- Step 2: Use the ruler to accurately measure the distance between the two opposite inner edges of the bracelet (in millimeters - mm). Measure at the widest point.
Result: This measurement is the Inner diameter (Ni), usually measured in millimeters (mm).

Method 2: Measure with a tape measure "Measure wrist circumference" (Method for chain bracelets/soft bracelets)
Tools
- A soft string (or a strip of paper)
- A tape measure or ruler
How to do it
- Step 1: Wrap the soft string or strip of paper snugly (not too tight, not too loose) around the wrist at the position where you usually wear the bracelet.
- Step 2: Mark the exact meeting point of the string.
- Step 3: Straighten the string and use a ruler to measure the length of that section (in centimeters - cm).
Result & Important note
This measurement is the wrist circumference. To get the bracelet length, you need to add 0.5 cm to 1 cm to this measurement depending on whether you prefer a snug or loose fit.
NOTE: For Diamond bracelets or bracelets with thick designs, you should add at least 1 cm to ensure comfort when wearing.

Method 3: Hand circumference measurement method
Tools
- Soft string
- Ruler
How to do it
- Step 1: Close your fingers together as if putting on a bracelet, bringing your thumb to touch your little finger.
- Step 2: Use the soft string to wrap around the widest finger joints (usually the thumb knuckle and opposite joints).
- Step 3: Mark the meeting point and measure the length of that string (Hand circumference C)
- Step 4 (Calculate Ni): Take the hand circumference result and divide it by 3.14 (pi) to get the inner diameter

How to measure jade bracelet size
Jade bracelets are usually rigid circular bracelets without clasps, so you need to measure so that the bracelet can pass over the hand rather than just fit the wrist.
- Step 1 (Position): Close your fingers together as if putting on a bracelet, bringing your thumb to touch your little finger.
- Step 2 (Wrap the string): Use the soft string to wrap around the widest finger joints (usually the thumb knuckle and opposite joints).
- Step 3 (Measure hand circumference): Measure the length of that string (Hand circumference C).
- Step 4 (Calculate Ni): Take the hand circumference result and divide it by 3.14 to get the inner diameter (Ni): Ni = Hand circumference / 3.14
For rigid bracelets, if the ni measurement falls between two sizes, always round up to ensure the bracelet can pass over the hand without getting stuck.
How to measure Pandora bracelet size
Pandora bracelets (or bracelets that need space to add charms) are usually soft-string types. How to measure Pandora bracelet size requires a certain amount of extra room so the bracelet does not become tight when you add charm beads.
Standard formula: Measured wrist circumference (according to method 2) plus 2 cm (to allow space for charms and a natural drape).

Important notes for accurate measuring and size selection
- Measurement time: You should measure at the end of the day or when your body is warm, because at that time the wrist tends to expand more than in the morning.
- Rigid bracelets must pass over the hand: For bangles/jade bracelets, the most important size is the size that passes over the hand, not the size that fits the wrist. If the measurement falls between two ni sizes, always round up to ensure the bracelet can be worn.
- Comfort: For bracelets, always add at least 0.5 cm so the wrist is not marked.
