Cadman by PJMiller Cadman by PJMiller
This is the Cadman font.

I have two friends who are dyslexic and they both expressed the need for a clear and legible font so I made one.

The name of the font is an indirect reference to one of these people who spends a lot of his time using CAD systems.

I don't know if a specific font for dyslexia is a good thing or not, certainly some fonts are more legible than others.

My hypothesis is that the success of fonts which have been specifically designed for people with dyslexia is a placebo effect.  The reader expects the special font to be easier to read so they put extra effort into reading the type.  Knowing that a typeface has been specifically created to address one’s needs may well provide useful motivation that enhances concentration and engagement.  Then, having better understood text for having made an effort to read it, the reader credits the enhanced comprehension to the special font rather than them having put in extra effort to comprehend it.

However having said that some fonts are easier to read and comprehend than other so why not make a font which fulfills all the criteria, it certainly cannot make the situation any worse.

The Cadman font has been designed to be as legible as possible.  There is a lot of opinion on the Internet about which fonts are suitable for dyslexic people and much of it is contradictory.  This is only to be expected, people are different from one another and what is suitable for one is not suitable for all.

However there are some characteristics which are commonly accepted as making a font more suitable for use by dyslexic people.

     Good ascenders and descenders
     Wide apertures
     b and d distinguished from each other not just mirrored
     p and q distinguished from each other not just mirrored
     Different forms for capital I, lowercase l and digit 1
     Rounded g and rounded a as in handwriting
     r & n together (rn) should not look like m
     The f character has a descender to make it more unlike a turned t
     M and W should be distinguished from each other and not just be mirrored
     6 and 9 distinguished from each other not just rotated
     The use of distinct letterforms where confusion could arise
     A slightly looser spacing than normal

Cadman fulfills all these criteria. But Cadman is not just for people with dislexia.

Cadman is suitable wherever a clear and legible sans serif font is required.  It has Bold, Italic and Bold Italic. 

There are many open type features including SMALL CAPITALS, fractions and ordinals.  There are two stylistic alternatives which change the digit zero from dotted to slashed zero or blank zero.

Cadman contains a Greek alphabet suitable for mathematics and many Mathematical Operators, Letterlike Symbols, Miscellaneous Symbols and Dingbats.

Enjoy !

Oh my god I have wanted a font like this for ages, but all the dyslexic fonts I'd seen before this were either pay-for-use or kinda ugly.  Thank you for giving me an alternative!

Thank you.  I'm glad you like it.

In my opinion there is nothing special about 'Dyslexic' fonts, but I think they should try to be as legible as possible.  A dyslexic font is whatever font the dyslexic person is comfortable reading and there are many different opinions on this.

Yeah, let me restate: I've been wanting fonts that are as legible and clear as possible, given the inherent impossibility of achieving that for everyone.

May I (with credit and link back, of course) use this font for my website?  I've been trying to find a clearer, better font for it, and I think this would suit my needs better than others I have around.

You may use it for whatever purpose you desire, commercial or non-commercial without any obligations or acknowledgements.  Furthermore under the SIL Open Font License you can modify it to your requirements if it doesn't suit, pass it on to other people and pass your modified version on to other people (under a different name).

The only thing you may not do is sell it.

I think that's right: Cadman is among the best I've seen thus far, but like you said, it's not as if one font system could be the best possible for each and every dyslexic reader out there. For my use, I know I could design a font that would work even better for me. Part of this is that I'm legally blind as well as quite severely dyslexic, and I'm legally blind in a particular *way*. Furthermore, I would have to design not only fonts for onscreen work, but for printed documents and for video subtitles/captions as well, since they each would serve different — and not always compatible — needs.

When I have finally gotten all the parts on sale, I'm going to build a new PC that can safely run font-designing software. (Right now I'm using a small 5.5-year-old laptop that overheats if I try to run anything like that!) So eventually I may create such fonts at least for my own needs. And share them with the world, since why not?

I can highly recommend Font Creator by High Logic.  See…

p.s. I have no connection with this company apart from using their products.
