What scale is Warhammer 40k?

Answer 1

Warhammer 40k works primarily with 25mm models, with 25mm being approximately equal to 1 meter. However, this is the scale of the model's bases, some obviously being bigger, for the bigger models.

It's altogether different though when you look at the size of the tables being played on. The typical table is 4'x6', and when you compare this to the fact that most battles in reality would take place over an area of many square kilometers, the 25mm:1m scale doesn't come close to comparing.

So the Warhammer 40k rule system uses abstract rules and measurements to try capture the scale, but make the game still playable on an average table.
