Huh, a quick look at google says its just called Standard ( vs wide or skinny, or square cut..that was a mod fashion for a bit ) although I bet if you looked into the history of the proto-ties ( cravat, etc) you could find something ...ties tend to be named by the knot used to tie them rather than the shape.

Thanks for looking. I knew there probably wasn't a term for it when I couldn't find one, but I don't know anything about men's clothing so I thought there might be some term I just hadn't heard.

Searching through Put This On I'm not finding a proper name for the "standard" tie.

The general idea is that tie width is in proportion to lapel width. I don't think there's a name for a traditional width lapel either. There are skinny, wide and...standard/default/traditional or whatever.
