I'm recently re-doing a couple of company forms. These used to be just regular PDFs, which would have to be printed and then filled out.
With the move to a more paper-less office environment, I was tasked with making them state of the art, which includes making them editable, Since the originals were done with vector graphing programs, and not all made by the same person (and pre-dating company paperwork style guidelines), they're not all alike when it comes to style, and especially - typography.
I have a "standard set" of typefaces, encompassing around 400 typefaces, most of them designed for screen reading.
My standard go-to font when creating forms is Akzidenz Grotesk. This is a rather classic sans serif font, which I feel makes the best printed forms. Now that these are supposed to be mainly edited on-screen and then saved and archived digitally, I'm not so sure anymore. I have a condensed version of Ak.Gr. which may or may not be better for this.
Of course my almost immediate thinking is Helvetica Neue. But I see it everywhere, and I'm not even entirely sure if it's the best choice for this use-case.
My requirements are: Not too outlandish, and should be a grotesque font, no serifs, etc. Should be easy to read at smaller sizes. The text written in this typeface, won't be long, usually three to five lines at most, rarely more than that. Quite often each line will be on its own at the top of a text field or similar.
