TT Interphases Pro updates the familiar TT Interphases with expanded functionality and refined contours. Designers rebuilt letterforms and improved technical details to deliver a family that reads consistently across interfaces, screens, and print. The family preserves the neutral, readable nature of the original while adding Condensed widths, expanded Latin coverage, richer OpenType controls, and a powerful variable font.
Key Features
Refined Glyph Design
We reconstructed contours to achieve visual harmony and consistent rhythm. Tall lowercase characters and squared round shapes increase on-screen legibility. Closed apertures and repeated rounding forms produce comfortable reading in long text arrays and small UI elements alike.
Expanded Styles and Variable Axis
TT Interphases Pro delivers 37 styles: 18 uprights, 18 italics, and 1 variable font in the main family. The family includes a Condensed width that enables denser layouts without compromising readability. The variable font exposes axes for weight (Thin to Black), width (Condensed to Normal) and slant (0 to 11 degrees), giving designers precise control over typographic tone and space.
Monospace Subfamily
The TT Interphases Pro Mono subfamily complements the main family with equal-width glyphs tuned for coding and product design. It offers 6 weights (2 uprights, 2 true italics, 2 variable fonts) and an icon set that visually matches the characters.
Advanced OpenType and Technical Quality
The family contains 24 OpenType features in the primary family and 18 in the monospace subfamily. Features include tabular figures, numerators/denominators, multiple alternates for characters (such as a, l, y), and curated stylistic sets. The team rebuilt kerning and hinting from scratch for improved rendering across platforms.
Technical Details
Glyphs and Language Support
Each style contains up to 978 glyphs, providing extensive typographic coverage. TT Interphases Pro supports 212 languages; this broad coverage ensures reliable typesetting for multilingual interfaces, global brands, and internationalized products.

File Formats and Web Use
The family ships with modern web-ready formats and variable font files. Use the variable font for responsive typography that adapts weight, width, and slant dynamically with CSS. The static family weights ensure consistent fallback across browsers that do not fully support variable fonts.
Ideal Use Cases
User Interfaces and Mobile Apps
TT Interphases Pro excels in UI contexts where even spacing, high legibility, and neutral character shapes matter. The tall lowercase and closed apertures improve readability on small screens and dense layouts, while the Condensed width helps fit more information into limited space.
Web Platforms and Dashboards
Designers can use variable axes to tune typography for dashboards, product pages, and marketing sites. Tabular figures and currency-aware number features make the family practical for data tables, financial displays, and complex interfaces.
Coding and Design Systems
The monospace subfamily suits code editors, developer documentation, and design system components. Matching iconography and consistent widths create a unified visual language across product and engineering documentation.
