How is road bike frame size measured?

Traditionally it is the seat tube length in centimetres, but modern fit relies on stack (height) and reach (length) for accuracy.

Should I size up or down on a road bike?

If you are between sizes, size down for a sportier, lower position or up for comfort and a more upright back. Inseam and flexibility decide.
