Say...

I was feeling bored, and I decided to see just how big things could get. What's the biggest map you've ever done? It'll be fun to see how big people have made them.

I myself decided to enlarge the map for my WScrolling tutorial and see how big I could make it. I ended up with the attachment, a monster of a map measuring 108*90 tiles and filling up almost all of the 1:4 view.

Mine is 320x240, it's the world map in my game. If you count all the time I've spent on it you'll get a few weeks together. !_! How much time did you need for yours?

1000x1000 while messing around.
I did not spend very much time on it because I was just testing something.

Blizzard: Crap, I see my map's not anything special! It only took me, say, half an hour in total to make and detail it.

Zeriab: How detailed was your map, by the way?

I feel like enlarging my map. I suppose I'll see how big it gets.

Not very detailed XD
Well... It was actually just one gigantic maze
1000x1000 is really too big and you can't create one without doing some scripting.

YOU MADE A 1000x1000 TILE MAZE?

How big were the walls?

I suppose even an eventless map would lag at that stage.

:O Liar! RMXP only support maps up to 500x500!

(without scripting)

@Blizzad 

It was not eventless... There were over 20000 events 

Oof, I almost forgot the 500x500 tile limit.

What am I saying? I did forget the limit.

Ya the limit is 500x500. I use 2k3 and my world map is 500x500.

However there is no "main map" in my game therefore it will take several of these maps which will range in size of 350-500x350-500 to finish all the places.
