title blocks not ansi size

I've been doing a series of 2-d drawings, and I've been told that the drawings weren't coming through because they were to big. I've been going through these drawings, which I had set to B size, or C size, but when I measure the title block instead of it being 11x17, or 18x24 the title blocks are 128x168. I've tried changing the title block size in the properties, but I still don't get standard sized title block. Also I made a couple new 2-d files used SW title blocks, and all those were the standard sizes. Is this some kind of scaling thing?
