Size

The Size of a unit or structure indicates its general dimensions in the game. For buildings, this statistic is given as the size of the foundation along the two axes on the ground plane. A building's Height is given in a separate statistic. For the majority of buildings, the dimensions of their foundations form an area of impassable ground through which neither units may move, nor other structures be built (except possible upgrades for the structure itself), but there are exceptions.

Note that some structures may have much more exotic foundations than a simple rectangular field. In those cases, the size may be described in more complex forms.

Due to engine constraints, for units, the size is mostly irrelevant while on the field - vehicles occupy one cell, regardless of the size of their graphics, while infantry units occupy 1/3rd of a cell each, meaning that an empty cell can either hold a vehicle unit, or one to three infantry units. Size only matters for units when they enter a transport - some transports do not permit units above a certain size to board, even if the transport has sufficient empty space to fit them. Even if a transport would permit a unit on board, it may be that the transport does not have sufficient empty space to allow certain units on board, because other units already take up space inside it.
