Is there any font of the Fraktur style that has a light font style (like Helvetica Neue Light or Ultra Light)? Many Fraktur fonts I have seen on Internet are too thick.
Astloch (literally knothole) is a recently designed blackletter font, which is even thinner, but lacks a long s and typical blackletter ligatures. Also, some letter shapes are not historical, e.g., H, I, J, K and Z.
I have no knowledge of, nor have I ever been able to find, a truly light or thin Fraktur font. These are some of the pretty lightweights that I've found:
Kabinett-Fraktur Regular (aka Fraktur Mager) is pretty lightweight for a Fraktur font.
Lautenbach is a more modern approach, not really a 'classic' Fraktur, but also more readable imho.
Strassburg Fraktur is a truly lightweight Fraktur font.
Space winning frax is also a pretty lightweight Fraktur font, and features both round and long lowercase 's'.
I am the designer of Dequindre, a font mentioned in one of the other answers. I'll be releasing it soon (I neglected it as I was finishing up my MFA).
It will contain a historical long s and a number of ligatures (mostly of the f_ variety). It has 355 glyphs and has the necessary accents to support a good number of languages, so for instance if you for some reason want to set some Icelandic in Dequindre, you’ll be able to.
Most of the glyphs are Fraktur in design, though I did take a few liberties, e.g., the S glyph is in Schwabacher style.
