Here's the one I was talking about. It measures 20" (top to bottom at center) and 23" at it widest point (base). Mounted, it's 18" from the top of the shield to the top of the fairing. I'm about 6' tall. When I sat on this bike, I was still looking over the top of the windshield, if that helps you to get any type of reference ratio...
It's really not in bad shape for it's age. Some surface scratches, but no huge gouges or cracks...
Priority Mail (USPS) charges for a 6-10 business days delivery would be about $28.35...I was thinking about $25 for the windshield...But I'd be happy to settle for $50 total (including shipping)...Let me know if you're interested...
