It is a snowboard where the tip and tail are exactly the same width. This is the most common shape of a snowboard. There are two types of twin boards- a true twin and a directional twin. A true twin means the board is 100% symmetrical. The stance is centered, the flex is even, and the sidecut is radial. This is the shape you find mostly on freestyle boards. A directional twin has twin tips and sometimes a centered stance, but the flex is directional and/or the sidecut is progressive. This is the most versatile shape and is commonly found on all-mountain snowboards.

Some do and in the board stats it will say directional. the front is more pointed and the back is more rounded. some are more obvious than others. the opposite would be a twin or true twin which i recommend if you want to have fun
