A font is a collection of glyphs (character shapes).
Each glyph you draw becomes part of your custom typeface. Professional fonts align characters using
invisible guide lines called metrics.
Guide Lines Explained
Cap Height - Top of capitals
x-Height - Top of lowercase
Baseline - Where letters sit
Descender - Below baseline (g, p, y)
Pro Tips
•Keep consistent stroke width across all letters
•Uppercase letters touch the cap height line
•Letters like g, p, y extend below the baseline
Why Normalize Glyph Size?
Professional fonts require consistent proportions across all characters.
When you draw freehand, natural size variations occur. Normalization scales each glyph to match
the font's em-square (the standard unit of measurement in typography).
Without normalization, a small "a" next to a large "B" would look mismatched when typed together.
Enable normalization for usable text fonts; disable it only if you intentionally want size variation.
