Hi Charles,

you can check: Adobe has icons that indicate if a certain OpenType feature (like fractions) is available in the font in question:

FontShop offers a customizable view of the character set:

Other foundries/distributors have different approaches; but most of them mention the (un)availability of OpenType features in some way on their website.

National. See in the pdf specimen.

Proxima Nova.

All of our fonts contain arbitrary fractions.
For sans look at:
Tangent
ClearviewText
Giacomo 2.0

Besides Open Type, there are plenty of font sets that include expert collections which let you compose your own fractions, such as the FF Meta family or the Thesis fonts, or House Industries Neutraface. These fonts contain complete sets of numerators and denominators.

I come across this problem a lot, since I design primarily art books and cookbooks.

Alternately, you can create character style sheets for numerators (I usually make them 3 to 3.5 points smaller than the regular size shift them up 2 1/2 or 3 points. Sometimes I go up a weight if the family has enough subtlety) and denominators (also 3 points smaller but no baseline shift). Just remember to use the opt+shift+1 character for the slash.

Thanks to all. I think this is a useful thread to continue if anyone wants, but the designer went with Mark's Proxima Nova (she had to make a decision by the 19th).

Mark is SO THE MAN today - btw this thread and the multiple plugs for Kinescope - good business!

Patty, as a tidbit, the designer did post this:

this article by Mark clinched the deal:

In their latest versions, the following Adobe OpenType sans serifs all support arbitrary fractions:

Myriad Pro
Cronos Pro
Hypatia Sans Pro

Cheers,

Proxima Nova is so the font, and as Patty said creating style sheets is the move. Good habit.

*This occurs a lot with Helvetica Neue vs. the STD version. The baseline is about 2 points off as is the size, so initially you think it's the fractions... ugh

As far as I'm concerned, the only sane way is to have numerators, denominators and the fraction character all properly kerned, have the numerators also kerned with full-size numbers (oldstyle and lining) and a fractions feature set up. That way, the InDesign-tagged-text file can have a code around the fractions, and when that file is imported, everything is done.

Of course that doesn't work if you don't use OpenType.
