Lettering & Type-Design Tools & Calculators
Free, practical calculators for hand-lettering, calligraphy, and type design — pair typefaces, measure x-height and spacing, convert tracking, generate a type scale, plan a nib angle, and snap a layout to a baseline grid.
Font Pairing Suggester
Pick a typeface classification — humanist serif, geometric sans, script, blackletter, and more — and get complementary pairings with real, freely available typeface examples.
X-Height & Line-Spacing Calculator
Turn a font size and x-height ratio into pixel measurements, work out a line height from a leading multiplier, and get a suggested leading for a given line length.
Letter-Spacing & Kerning Guide
Convert a tracking value between em, percent, and the per-1000-em units used in page-layout software, and get a general tracking suggestion by point size.
Poster Type-Scale Generator
Generate a full modular type scale from a base size and a ratio — golden ratio, perfect fourth, major third, and more — for consistent poster and layout hierarchy.
Nib-Angle Guide
Work out the stroke width a broad-edge calligraphy nib produces in any direction for a given pen angle, and find the thinnest and thickest strokes.
Baseline Grid Calculator
Snap a desired line height to the nearest multiple of a baseline unit, and work out how many lines of text fit on a page.
