How it works

A digital font is a set of vector outlines — one per character, called a glyph — plus the spacing rules that set them side by side. To make a font from your handwriting you need those outlines, and tracing is how you get them: draw the letters, scan them, vectorize them, then assemble the glyphs in a font editor that exports an installable OTF or TTF file.

You’ll need paper and a good black pen, a scanner or a phone, and a font editor. FontForge is free and open source, runs on Windows, macOS, and Linux, and does everything in this guide. Glyphs (macOS) and FontLab are polished paid alternatives; BirdFont is another free option.

Each letter drawn in its own box on a shared baseline and x-height, so the traced glyphs line up with little adjustment.

Draw the characters

  • Rule a grid first. One box per character, with a baseline and an x-height line (the top of a lowercase x) in every box. Print it in a light color — pale blue works well — so it can be hidden in the palette before tracing.
  • Decide on the character set. At a minimum: A–Z, a–z, 0–9, and everyday punctuation such as . , ; : ! ? ’ “ ” ( ) - & @. Add accented letters if you write in a language that uses them.
  • Use a bold, even pen. A felt-tip or a 0.5–1 mm fineliner gives solid lines that trace cleanly. Ballpoint is thin and patchy; pencil is too gray.
  • Write larger than you normally would — capitals around 2–3 cm tall. More ink means more pixels per stroke and smoother outlines.
  • Draw each letter a few times and keep the best.

Scan the sheet

Scan at 300–600 dpi and crop to the grid. If you photograph the sheet instead, shoot straight down in even daylight. Save as PNG, and if the paper isn’t white, push it there with Levels or Curves in any photo editor — the guide to scans covers this in detail.

Trace the glyphs

  1. Upload the first image — it’s traced automatically.
  2. Open Settings → Palette → Choose palette. Slide Simplify Colors down until only ink, paper, and the grid color remain, then hide the paper and the grid.
  3. Set the ink swatch to pure black, #000000.
  4. Keep the General use preset: filled shapes with cut-outs. That makes the counters — the enclosed spaces in a, b, d, e, g, o, p, and q — real holes in the letter, which is exactly how a font defines them.
  5. Under Advanced → Detail, turn on Refine curves to color edges. Leave Fit to lines & arcs off: handwriting is all curves.
  6. Raise Minimum area a little to clear ink spatter, and check that the dots on i and j survive.
  7. Apply changes, check the letters in Outlines over original, and download as SVG.

Split the sheet into letters

Font editors take one glyph at a time. Open the SVG in a vector editor — Inkscape (free), Illustrator, or Affinity Designer — and either copy each letter’s shapes as you go, or save each letter as its own small SVG. If any grid lines survived the trace, delete them now.

Import into a font editor

In FontForge, create a new font, double-click a glyph slot — say “a” — to open it, then choose File → Import and pick that letter’s SVG. Scale and move the outline so it sits on the baseline and reaches the x-height line. Repeat for every character. Glyphs and FontLab also accept outlines pasted straight from a vector editor.

Then run the editor’s clean-up tools. In FontForge they’re under Element: Remove Overlap, Correct Direction, and Add Extrema. Traced outlines are clean, but fonts have stricter rules about contour direction and point placement than illustrations do.

Spacing, kerning, and export

  • Side bearings are the space on either side of each glyph. Set them so words look evenly spaced: start with n and o, then match the other letters to them.
  • Kerning adjusts specific pairs that look too far apart with ordinary spacing — AV, To, ry. Kern the worst pairs first; a handful makes a visible difference.
  • Export an OTF or TTF (in FontForge, File → Generate Fonts), install it, and type a test paragraph. Expect a few rounds of tweaks.

Tips for a better font

  • Consistency beats neatness. Same pen, same size, same slant, and the font will look like a font.
  • Print, don’t join. A standard font places letters side by side. Joined cursive needs OpenType contextual alternates — an advanced topic. Separate letters are the easy route.
  • Keep the scans. They’re your masters. Redrawing one letter later is easy when the rest of the sheet is safe.
  • The same method works for icons and hand-drawn symbols: draw, trace, and import them as glyphs to build a symbol font.
