How tall do you need to be play a full-size double bass?

There is no specific height requirement to play a full-size double bass, as players come in all shapes and sizes. While a taller person may have an easier time reaching the higher positions on the instrument, a shorter person can adjust the endpin to lower the instrument to a comfortable playing position. Many professional double bassists of all heights play the instrument successfully, and there are many resources available to help players of all sizes find the right instrument and technique.
