Print this page and cut out the measure so that you can get a better idea of the number of links to use for your bracelet.
The printed page should produce a 23 centimetre rule, but if you have any doubts, you can always check the measure using a metric ruler or tape measure after printing. Each division should be one centimetre approx. There are 20 charm links in the picture, measuring 205 millimetres / 20.5 centimetres.
