Maximum Map Size

[Raybrite]

I have been looking for about an hour and cannot find the answer.
I would like to know what is the maximum map size I can build? I put in 400 high and 400 wide and it looks like the original size.
Thanks, I know this is a very elementary question.
Thanks for bearing with me.

It's 500 x 500 or actually 250000 tiles. Careful making something that large as it causes the game to take up a lot of memory when you have it filled with tiles and events. Tends to slow down the game. The only way you should need to make something this big is if your making a world map. otherwise smaller maps is what you should concentrate on. Cause you can have 999 maps by default. A script can be used to have more.
