Handwriting to Font

What it is for

You want a font that looks like your own handwriting — for invitations, a comic, a school worksheet or a personal website. The tool works in two steps. Leave the page fields empty and it returns a printable template PDF for the character set you choose. Write one character per box, photograph or scan the pages and upload them: the tool finds each page, straightens it, traces every box and writes a TrueType font.

The same engine runs in Lumina's Type Lab → Glyph Lab on your device, where you can also untick smudged letters before downloading. The tool does not join cursive letters, invent missing characters or add ligatures: one box gives one glyph.

Worked example

First we asked for a template with Basic Latin with German letters on US Letter. Result: "Handwriting template with 83 characters on 3 US Letter pages", 36 boxes per page, and a 9 KB PDF to print at 100 %.

Then we ran the second example, a synthetic phone photo of the Capitals template with 16 letters written in, shot at an angle on a grey table.

• Pages read: page 1, A4, turned by 0°, code strip read, 4.1 pixels per millimetre, 16 of 42 boxes with ink.
• Glyphs traced: 16; Characters without a glyph: 26 (B, C, D … left empty on purpose).
• Writing slant: 7°; Kerning pairs: 104 (for example A–V is pulled together, H–H is not touched).
• DemoHand-Regular.ttf: every read-back check passed (12 table checksums, 17 of 17 characters mapped, outlines read back point for point).

The sample "HALT! TO VANE 17." is drawn from the new font's outlines.

How to read the result

• Pages read tells you which page each image was, whether it was upside down or sideways (Turned by), and the resolution. Below about 4 pixels per millimetre letters get blocky; use a sharper photo or a 150 dpi scan.
• Glyphs lists every character of the template: Traced with its contours, points and advance width, Empty box, or Page missing when you did not upload that page.
• Writing slant is the lean of your letters. Spacing is measured along that slant, as in an italic font, so slanted handwriting is not spaced too loosely.
• Read-back checks are the same checks as the TrueType font builder: if one fails, do not install the font.
• Download the font project gives a .lumina-font.json you can open in Font Foundry to fix outlines, adjust kerning or add a Bold master.

Tips and common mistakes

• Print at 100 %. "Fit to page" changes the box size and the letters come out too small or too large.
• Use a dark pen. If thin strokes break up, raise Ink level (for example from 0.6 to 0.7); if shadows or guide lines appear as blobs, lower it.
• Keep all four black corner squares and the small code squares at the top in the photo, with even light and no fingers on the page.
• Sit letters on the solid baseline. The font keeps each glyph's height where you wrote it, so a letter written too high floats in text.
• Automatic kerning strength 0 turns kerning off; 1 closes every gap to the stem-to-stem distance. 0.6 is a calm middle.
• Smooth curves gives a pen-like outline; Straight segments keeps a more angular, marker-like look.

FAQ

Can I add more pages later?

Yes. Upload up to three pages per call here, or up to fifteen in Glyph Lab. Each page carries its own code, so the order of the files does not matter and a page uploaded twice simply replaces the first copy.

Why are some of my letters missing?

A box counts as empty when nothing in it is darker than the ink level. Faint pencil, a very thin pen or a strongly overexposed photo cause this. Raise the ink level or rewrite the letter darker.

Does it work with joined-up writing?

No. Each box becomes exactly one glyph, so write separate letters. Joined cursive needs contextual alternates, which this tool does not create.

Who owns the font?

You do. Your handwriting and the generated outlines are yours; add your own license text in Font Foundry if you share the font.
