Sans maker is an AI-powered typography tool that generates custom sans-serif typefaces based on your design parameters. Unlike basic font generators, it creates complete font families with multiple weight variations, automatic optical kerning adjustments, and geometric consistency across all characters. The tool uses machine learning trained on thousands of professional sans-serif fonts to ensure proper x-height ratios, stroke consistency, and character harmonization.

How do I control the geometric style of my sans-serif font?

Adjust the geometric parameters including stroke modulation (0-100% contrast), terminal style (straight, angled, or rounded), and aperture width for characters like 'a', 'e', and 's'. You can also set the x-height ratio (typically 60-75% of cap height), control corner rounding radius, and define stem width proportions. The tool provides real-time preview of how these parameters affect readability at different sizes.

Can I export fonts for both web and desktop use?

Yes, sans maker exports in multiple formats: OTF and TTF for desktop applications, WOFF and WOFF2 for web embedding, and variable font formats that include all weight variations in a single file. Each export includes proper OpenType features, hinting for screen rendering, and licensing metadata you can customize for personal or commercial projects.

How does the AI handle optical corrections for different font weights?

The AI applies weight-specific optical adjustments, adding ink traps at joints in heavier weights to prevent visual clotting, and adjusting counter spaces to maintain consistent perceived density across the family. It automatically compensates for stroke width in curved characters, ensures consistent stem thickness at different angles, and maintains visual weight balance between uppercase and lowercase at each weight step.

What character sets are included in generated sans fonts?

Each generated font includes full Latin extended character sets with 380+ glyphs covering Western, Central, and Eastern European languages. This includes uppercase, lowercase, numerals (lining and old-style options), punctuation, mathematical operators, currency symbols, and common ligatures (fi, fl, ff). You can also enable extended sets for Greek, Cyrillic, or custom glyphs specific to your project needs.

How to use sans maker

Steps to get you started in BasedLabs.

Step 1

Define Your Sans-Serif Foundation

Set geometric parameters and style direction

Start by selecting your base geometric style: humanist (organic curves with calligraphic influence), grotesque (minimal stroke contrast with closed apertures), or geometric (pure circular and rectangular forms). Adjust the x-height ratio between 60-75% for optimal readability—higher ratios work better for UI text, while lower ratios suit editorial contexts. Set your cap height and ascender/descender proportions, keeping in mind that balanced ascenders (typically 120-130% of x-height) improve line spacing efficiency. Pro tip: Use the 'optical size' parameter to automatically adjust stroke contrast and spacing for intended use size (display vs. text).

Step 2

Configure Weight Range and Interpolation

Build your complete font family

Define your weight spectrum by setting minimum (thin/hairline at 20-40 stem width) and maximum (black/heavy at 180-220 stem width) values. The AI generates intermediate weights using multiple-master interpolation, ensuring smooth transitions and consistent stroke relationships. Enable 'optical weight compensation' to adjust perceived weight in curved vs. straight strokes—curves typically need 5-8% more mass to appear optically equal. Configure italic or oblique variants with slant angles between 8-15 degrees, and choose whether to apply true italic construction (with structural changes to 'a', 'f', 'g') or simple slanting.

Step 3

Refine Spacing and Export Production Files

Optimize metrics and generate font files

Fine-tune letter spacing using the AI's contextual spacing engine, which analyzes character pair frequencies and optical density. Set tighter tracking for display sizes (-20 to -40 units) and looser spacing for small text (+10 to +20 units). Review the automatically generated kerning pairs (typically 500-2000 pairs for comprehensive coverage) and adjust exceptions manually if needed. Before export, validate OpenType features including stylistic sets, fraction support, and tabular figures. Export your complete family with embedded naming tables, proper font metrics (ascender, descender, line gap), and hinting profiles optimized for Windows ClearType, macOS CoreText, and web rendering engines.

Complete Font Families in Minutes

Generate production-ready font families spanning thin to black weights with mathematically precise interpolation between masters. The AI ensures consistent stem weights, maintains optical balance across all weights, and automatically adjusts counter spaces to prevent visual clogging in heavier weights. Each family includes properly matched italic or oblique variants with weight-specific slant compensation, giving you 18+ font files that maintain perfect stylistic harmony across your entire typographic system.

Professional-Grade Kerning Intelligence

Advanced optical kerning engine analyzes character shape interactions and generates pair-specific adjustments based on visual density rather than simple sidebearing math. The system handles complex scenarios like punctuation placement, diagonal stroke interactions (AV, WA), and numeral spacing for financial tables. Includes class-based kerning for efficiency and exception pairs for optical perfection, reducing manual kerning work by 95% while achieving professional typographer-level spacing quality.

Variable Font Technology Built-In

Export modern variable fonts that embed your entire weight range in one compact file, reducing web page load by 60-75% compared to loading individual weight files. Variable fonts enable dynamic weight adjustments via CSS, allowing responsive typography that adapts weight based on screen size, user preferences, or interactive states. The tool automatically generates proper variation axes, includes named instances for common weights, and optimizes the font's internal structure for minimal file size and maximum browser compatibility.
