How to Create a Font from Your Handwriting
Handwriting Capture is a Pro feature that turns your actual handwriting into a machine-ready single-line font. You print a calibration template, write every character with a black pen, photograph the completed sheet, and Pathhaus automatically extracts your letterforms, vectorizes them, and loads them into the SLF Tracer for review. The entire process takes about 30 minutes from template to published font.
What you need before you start
A printer, a sheet of plain white paper, a black ballpoint pen or felt-tip marker, and a phone or camera to photograph the completed template. A Pro or Enterprise subscription is required. The tool is at pathhaus.com/create/handwriting-capture.
Step 1 — Download and print the template
Open the Handwriting Capture page and choose your template variant. The Full template has all 78 characters: uppercase, lowercase, digits, and punctuation. The Short template has uppercase letters and digits only — ideal for display fonts or engraving labels where you only need capitals. Choose your page size (A4 or US Letter) and click Download Template. Open the downloaded SVG file in any browser, go to File → Print, and print at 100% scale with no scaling or fit-to-page. The template must print at its exact dimensions for the registration marks to work correctly.
Step 2 — Fill in every glyph slot
Use a black ballpoint or felt-tip pen. Press firmly — the extraction algorithm works on contrast, and faint strokes produce poor results. Write each character inside its labelled slot. The slot has three guide lines: a top ascender line, a baseline, and a descender line. Write as you normally would — the guide lines are there to help you keep consistent scale, not to constrain your style. Leave the calibration slot at the bottom of the template blank until last, then draw a single horizontal line across it. This stroke tells the algorithm your natural stroke width.
Step 3 — Photograph the completed sheet
Lay the completed template flat on a table. Do not hold it in your hands — any curl or shadow will reduce quality. Use even, bright lighting with no shadows falling across the template. The entire sheet must be in frame — all four corner marks must be visible. Shoot straight down if possible, though the algorithm corrects for moderate camera angles using the four registration marks. A typical phone camera in good light produces excellent results. Aim for a file of at least 200 KB (higher resolution is better).
Step 4 — Upload and extract
Upload your photo on the Handwriting Capture page and click Extract Glyphs. The algorithm runs entirely in your browser — nothing is sent to a server. It detects the four registration marks in the photo corners, corrects the perspective, extracts each glyph slot, and binarises the ink against the paper background. The extraction typically takes 10–30 seconds depending on your device. A progress bar shows each step: loading, detecting marks, correcting perspective, calibrating stroke width, and extracting glyphs.
Step 5 — Review the extracted glyph bitmaps
After extraction, a grid shows every glyph as a small black-and-white preview image. Check each one. If a glyph is missing, blurry, or incorrectly extracted — perhaps because that slot was smudged or the ink was too faint — click it to skip it. Skipped glyphs are excluded from the font but you can always re-run the extraction or add them manually in the Tracer later. When you are satisfied with the glyph set, enter a name for your font and click Send to Tracer.
Step 6 — Refine and publish in the SLF Tracer
The SLF Tracer opens with your handwriting pre-loaded. Each glyph has been converted from a bitmap into bezier curves using the Zhang-Suen centerline algorithm and Catmull-Rom bezier fitting. The result is 80–85% clean automatically — most glyphs will be usable as-is. Click any glyph to open the path editor and adjust individual nodes: drag nodes, delete stray points, smooth curves. When you are happy with the full set, enter your font name, optional tags, and click Save to Library. Your handwriting is now a published SLF font available in your creator dashboard.
Tips for best results
Write slowly and deliberately — faster writing tends to have thinner, more variable strokes that are harder to extract cleanly. Use the same pen throughout the entire template for consistent stroke width. If your extraction confidence score shows below 70%, re-photograph in better lighting or move the template to a higher-contrast background. If a particular glyph consistently extracts poorly, skip it and draw it manually in the Tracer node editor from scratch.
