How to Create Custom Fonts with xFontCreator — Step-by-Step TutorialCreating a custom font can be deeply rewarding: it gives your brand or project a unique voice and gives you full creative control over letterforms, spacing, and personality. xFontCreator is a beginner-friendly tool that balances simplicity with enough advanced controls to produce professional results. This step-by-step tutorial walks you through the process from initial concept to exporting a usable font file.
What you’ll need
- A copy of xFontCreator installed on your computer (Windows/macOS as applicable).
- A drawing tablet or mouse.
- Reference material or sketches for the typeface concept.
- Optional: vector editor (Adobe Illustrator, Inkscape) for detailed glyph artwork.
1. Plan your typeface
Before opening xFontCreator, make design decisions that will guide the entire process:
- Purpose: display, body text, logo, or decorative.
- Style: serif, sans-serif, slab, script, geometric, monospace.
- Character set: start with Basic Latin (A–Z, a–z, digits, basic punctuation) and add more later.
- Mood and constraints: high contrast vs. low contrast, condensed vs. wide, x-height proportion.
Sketch several letters (especially H, O, n, o, a, e) to define proportions and stroke terminals.
2. Set up a new project in xFontCreator
- Open xFontCreator and create a new font project.
- In the font properties panel, enter the font name, family, weight (e.g., Regular), and version. These metadata fields will appear in font menus after installation.
- Set units-per-em (UPM). Standard is 1000 or 2048; for most projects choose 1000 for simpler math.
- Adjust baseline, ascender, and descender values to match your intended x-height and line-spacing behavior.
3. Import or create glyph outlines
xFontCreator supports building glyphs by drawing directly or importing vector artwork.
- To import, export your outlines from Illustrator or Inkscape as SVG or EPS and use xFontCreator’s import feature. Ensure paths are clean and all shapes are closed.
- To draw in xFontCreator, use the pen and brush tools. Start with uppercase and lowercase skeletons for H, O, n, o, a, e to set stroke thickness and curve rhythm.
Tips:
- Keep stroke contrast consistent across letters.
- Use as few nodes as necessary for smooth curves.
- Avoid overlapping contours; use boolean operations to combine shapes when needed.
4. Refine letterforms and consistency
Consistency is key to a cohesive typeface. Use these checks:
- Compare stems, bowls, and counters across letters.
- Align terminals and endings: decide whether strokes end vertically, diagonally, or with a curve.
- Use guides and measurement tools in xFontCreator to match widths and heights.
- Pay special attention to optical corrections: circles (O, o) often need slightly different proportions than squares (H, n) to appear visually consistent.
5. Build spacing and kerning
Good spacing makes a font legible and professional.
- Metrics: Set sidebearings (left and right spacing) for each glyph so that average spacing across common letter pairs looks balanced.
- Optical spacing: visually judge pairings like VA, AW, To and adjust sidebearings accordingly.
- Kerning: create kerning pairs for problem combinations (AV, WA, To, Ty, LT). xFontCreator should let you enter numeric kerning values and preview text to test.
- Test using word and sentence samples at different sizes.
6. Create diacritics and additional characters
Once the base Latin set is stable:
- Make accents using anchors or by copying base glyphs and adding diacritics.
- Add numbers, punctuation, and currency symbols. Ensure numerals’ height and weight match lowercase or uppercase numerals depending on your design (oldstyle vs. lining).
- Consider adding alternative glyphs or stylistic sets if you want variety (contextual alternates, ligatures).
7. OpenType features and advanced options
xFontCreator typically supports OpenType features—use them to add professional behavior:
- Ligatures: fi, fl, ffi, ffl.
- Kerning classes: group similar glyphs to speed kerning adjustments.
- Small caps, alternates, and stylistic sets: define these in the features panel if your design requires them.
- Mark positioning: for complex scripts or precise accent placement, use anchors and mark features.
8. Testing and iteration
Thorough testing prevents issues after export:
- Test at multiple sizes (small body text and large display sizes).
- Print samples to check how details render on paper.
- Use lengthy passages and UI mockups to check spacing in real contexts.
- Fix issues, then re-test. Iterate until spacing, balance, and legibility feel right.
9. Hinting and optimization
Hinting improves on-screen rendering, especially at small sizes.
- xFontCreator may offer automatic hinting; use it as a starting point.
- Manual hinting can be applied to key glyphs (H, I, M, n, o) for pixel-perfection on low-resolution displays.
- Optimize path complexity—remove unnecessary nodes to reduce file size and rendering complexity.
10. Exporting the font
When satisfied:
- Update font metadata (designer, license, copyright).
- Choose formats: TTF for broad compatibility, OTF for advanced OpenType features, WOFF/WOFF2 for web use. Export multiple formats if you’ll use the font across platforms.
- Validate the font with xFontCreator’s built-in checker (if present) or third-party validators to catch common errors.
11. Licensing and distribution
Decide how you’ll license the font:
- Free/open-source (SIL Open Font License) allows broad use and modification.
- Commercial/proprietary licenses restrict usage—consider embedding, app, and webfont terms.
Include a README and license file with your font package.
12. Troubleshooting common issues
- Jagged curves: reduce nodes and smooth Bézier handles.
- Crowded spacing: widen sidebearings and add kerning pairs.
- Misplaced diacritics: use anchors and test across accented glyphs.
- Feature not applying: check syntax in feature code and that glyph names match feature references.
Example workflow summary
- Plan concept → set up project → import/draw skeleton glyphs → refine shapes → set spacing/kerning → add diacritics & features → test & hint → export & license.
Creating a font is iterative. xFontCreator makes the technical parts accessible so you can focus on letterform quality and consistency. Start small (Basic Latin) and expand as you gain confidence.
