Tips

Create a brief for what you want out of the font
Design font on paper first
Use control characters to help design (lowercase=n, o; uppercase=H, O)
Switch to PC by uploading your sketch
Use a font editor and create the glyphs
Test the font in typing mode, at different sizes and in paragraphs

Kerning

You have to kern each letter individually
Kerning is all about feeling
Test kerning when size changes

Letters to keep an eye on
1. Slanted Letters: A, K, V, W, Y
2. Letters with arms or cross-strokes: F, T, L
3. Letter combinations: W or V + A; F or T + a lowercase vowel
Two straight lines need the most space: II > IO > OO
Try flipping the letters upside down, so you can see the spaces unbiased

Hinting

Happens automatically, but can be set manually in font editors with TrueType instructions
e.g. SNAGW (Set Angle Weight), MDAP (Move Direct Absolute Point)

Design Basics

Words must be spaced more than letters, to form distinct units.
