¡Mapa Gigante! is a web site that lets you make high resolution GIANT MAPS!

 
Here are some random people enjoying their Giant Maps... look how happy they are!
What do you want a Giant Map of?

Practically you're limited by how large a web page your browser can support, which is a function of your browser and how much memory and patience you have. I've personally been astounded by how big a map Firefox can tolerate; I've yet to reach the limit of the browser's rendering engine.

I have an idea... why don't YOU try and make a REALLY BIG MAP and then e-mail us the dimensions and a picture!

Places like Kinkos (no affiliation) will print things for money (I've heard it's something on the order of $10/sqft). Heck, they even offer an online service with local pickup...

We here at ¡Mapa Gigante! enterprises are considering offering a printing service at a competitive price... if you're interested contact us and we'll get back to you!

The simplest way is to 'print' to a PDF file, which you can them import into photoshop and go crazy!

If you're an OS-X (Mac) user, it's on the 'print menu'. If you're a Windows user, there's not really a definitive answer, but I bet you can use the power of the Internets to figure this out on your own!

Short answer - no; not on ¡Mapa Gigante! However, if you want to rotate the map, Photoshop or The Gimp is a good way to accomplish this. Just print to an image file (see above) and import into your favorite photo munging softwares.

Just be happy I'm not using Comic-Sans.
