I want to save my file as a pdf and send it off to print but I cannot save it and the error that I am getting is that the “dimensions of this page are out-of-range.”
The maximum dimensions for a pdf file are 200×200 inches or 508×508 cm.
You can either send your printer the Illustrator file without converting to pdf if they can accept this or, so long as your document contains no raster images (ie photos or similar graphics from Photoshop), scale your artwork to say 50% and ask the printer to print at 200%. This will work fine for vector art as also suggested by Amy.
I think the size is the problem, this is just too big. Check with your printer about how to handle the file. If they can accept a native .ai file, then you can reduce the size and they can upsize it at their end. Also see what resolution they need. If it’s going to be viewed at a distance, then it can be reduced in size at your end, even as a .pdf, and they can resize it as needed, eve with a lowered resolution it will look fine.
You won’t be allowed to create a PDF unless you go 199 or below.
