Books on developing font weights?

I'm struggling with the creation of different weights for typefaces. There seems to be a science to adjusting weights. Can anyone recommend books or other resources that impart this wisdom?

    You can ask Gunnlaugur SE Briem at ( for his old website "Notes on type design" which sadly is not online anymore. Pity, I think it was an useful resource.

    Also you can get Creative Lettering Today by the multi talented Michael Harvey. There are some tips on making bold versions in this book (and so much important information and advises). Strongly recommended.

  • Thank you very much, Ramiro!

    Get The Modification of Letterforms by Stanley Hess. It explains how to build families with a variety of weights and widths. It’s a forgotten classic of type design.

    @Oliver Weiss (Walden Font Co.) First of all: there is no science.  :-)  But: below is a particularly useful diagram (page 59 in Frutiger's "Type Sign Symbol", 1980).

    What's more obscure (and contested) however is how to determine multiple weights on a gradation (simply linear doesn't generally work out). I think there have been some good threads about that here.
  • That looks very familiar.
  • Just as a reminder, designing bold weight these days is closely related to interpolation. So it's not only about the look of the bolder weight, but also a glyph structure (if interpolation is planned), in terms of the number of nodes, their placement, contours starting points, and direction, avoiding interpolation "kinks" etc.


    Oldie but goldie resource is:

    Also, great tutorials about masters on the Glyphs forum.

    Usually, the manuals for drawing software also have some theory points besides only explaining tools for manipulating masters.


    As for the design of bolder weights, a few most important things would be:

    - The decision about stem weight for the thickest weight in the family. There is a reasonable limit to how thick the design can be because some letters (double-story lowercase g i.e.) have very limited space to add weight and still preserve any counters. Lucas De Groot's and Pablo Impalari's diagrams about "stem weight vs weight name" should be checked in this sense.

    - Once you know how much weight should be added, the next step is to decide where the weight goes. This varies, but in general, 3/4 goes "inside" the glyph, and 1/4 goes outside the skeleton. Because the vertical metric is fixed, that 1/4 which goes outside, makes bold letters "wider" in proportion than in lighter weights. Weight distribution is most important for lowercase because there is the least space here. As a matter of fact, lowercase letters are actually getting a bit higher than x-height in bolder weights, to accommodate this.

    Also, because there is more space to add weight in horizontal than in (almost fixed) vertical direction, usually horizontals get less weight than verticals, which means that bolder weights have increased contrast compared to lighter ones. This is true mainly for black weight. Classic bold weight probably can get away without obviously increased contrast.

    - Because white space is smaller for bolder letters, letter spacing is also smaller, which means side bearings are smaller than in regular weight.

    - Adding weight is not a straightforward process, and many letters require a special case scenario. Because of this, the most useful resource is to study existing typefaces, to overlay weights, and measure glyphs at some critical points, compare, etc.

  • Thank you all, you're being hugely helpful! 
  • That looks very familiar.
    Good memory.
    When I asked this very same question (ages ago) you told me to go look it up. In a book that cost ~$300 at that point IIRC. When you could've done what I just here...  :-)
  • More like $400 now!

    One copy on in Germany for under $200, one copy in the US at over $500.

    James has all the best books!
  • Sorry to do this to you guys but I got mine for $35 (thanks to a tip by erstwhile font friend Phan Nguyen).

    I was going to say, a lot of the diagrams (including that one) from Type Sign Symbol are also included in the more recent Adrian Frutiger Typefaces: The Complete Works, but looking it up I see that, since it's also out of print, it's fetching a pretty steep price as well.

    @Mark Simonson Checking... I'm seeing some copies for $150. I could never get myself to pay that much for it TBH. I think the most I've paid for a type book is $70 (the 1982 facsimile of Rudolf Koch's incredible "The type foundry in silhouette" of 1936).

    @Daniel Calders Thank you, I hadn't heard of that book – sounds pretty promising. Just bought a used copy for $8, free shipping!

    That's a deal/steal! It's a great book even for the full price, very underrated imho. Enjoy the read!
  • @Daniel Calders I got it! Yes, worth WAY more than $8. Thank you.
