Red sea 300xl overflow box size?

[OscarHaglund]

Does anyone know the size of the red sea 300xl overflow box? I want to start my aquascaping before I have a tank but I want to be ble to clearly mark out the overflow box so I dont end up building rocks into it.

4 inches from the back of the tank. 10.5 inches across.
