Indian Bangles are sized by their diameter, which is a measure of the length of a straight line passing through the centre of the bangle, terminated at both ends on the periphery (circumference) fo the bangle. The unit of measurement is inches.

An inch is further divided into 16 sections. So, when we say the bangle size is 2.8 (pronounced two eight), It means the the diameter of the bangle is 2 full inches plus 8 sections of the total 16 sections of the inch. This effectively converts to 2 inches + 8/16 inches, which is 2 inches plus half an inch. In other words the size will be 2.5″ (pronounced two point five inches)

Measuring your hand with a tape measure.

You will need a flexible tape measure or a piece of string and a ruler.

Make your hand as small as possible, as if you were putting on bangles, bringing your thumb and little finger together.

Using the tape measure (or string), measure the around your hand at the widest point (the tape measure should be pulled taught, not loose). Make a note of the actual circumference of your hand (if you used string, make a mark where the string meets, then measure the length of the string with your ruler to get your hand circumference).

Compare your hand circumference to the bangle circumference in the chart below. Purchase bangles that are the next size up from your actual hand measurement.
The table below will help you know the right size for your indian bangle.
