To choose the right road bike size based on your height, you should consider the frame size. Generally, for a person around 5'4" to 5'7", a small frame size (50-52 cm) may be suitable. For someone around 5'8" to 5'10", a medium frame size (54-56 cm) could work. Taller individuals, around 5'11" to 6'2", may find a large frame size (58-60 cm) more comfortable.
