Measure your chest circumference at the widest point of the rib cage. Take care to keep the tape measure as horizontal as possible.
Waist or waistband measurement
For the waist measurement, the waist is measured at the narrowest point. For this purpose, hold the tape measure as centrally as possible between the lowest rib and the hip bone.
Measure your hip circumference at the widest point and keep the tape measure as horizontal as possible. Attention: the hip circumference does not correspond to the belt circumference, but is approx. 10 centimetres below.
Stand vertically on the floor without shoes. Now measure exactly from the crotch to the inner ankle and keep the tape measure as vertical as possible. Or take a pair of trousers that fit you and measure the inner seam exactly.
