HOW TO KNOW YOUR HELMET SIZE?

Before buying a bicycle helmet you must know exactly the measurement of your head, for this use a flexible tape measure around the widest part of your head, about two fingers above the eyebrows. You can also use a piece of tape or string, and then measure the length with a ruler. Then compare the centimeters with the size offered by each brand.

Some general sizing parameters for adults are:

·         S: 51-55cm
·         M: 55-59cm
·         L: 59-63cm
·         XS: below 51cm
·         XL: above 63cm
·         Standard size (men):  54cm-61cm
·         Standard size (women):  50cm-57cm

Most children's helmets are one size fits all, with a range of 46cm-57cm.
