3. inseam

You should wear cycling shorts and take the measurements in bare feet or socks, no shoes. Feet approximately 20cm apart.

Put the level inside your legs. Pressure the level on your crotch, like it feels when sitting on your seat. Measuring the distance from the top of the level to the ground is the most important. Instead of a level you may use a cane or a stick if it feels more comfortable than a level. But it has to be absolutely horizontal.

Stand up against a wall. Set your feet approximately 20cm apart. Find the sternal notch in your neck. The sternal notch is the bony "V" beneath your Adam's apple. Measure the distance from the floor to the apex of the sternal notch.
