Where on the hand: Measured by folding the thumb across the palm: it should reach at least halfway up the lowest (third) phalange of the index finger.

What it looks like: Reaching the base of the index finger is long; falling well short of the halfway mark on the index's base phalange is short.

Cheiro: *"The longer the thumb, the more the power of will rules the actions; the shorter the thumb, the more brute force and obstinacy sways the nature."* Length is the direct measure of how far deliberate will governs the person.

Western reading: Cheiro's will-versus-brute-force formula is the governing Western statement.
