Microsoft Design Language

content before chrome

Born from Swiss typography and transit wayfinding, Metro strips away decoration to let information speak. Bold tiles, precise grids, and kinetic motion define an authentically digital design language.

Typography

type is the interface

In Metro, text itself is the design element. Oversized lightweight headings create hierarchy through scale and weight, not ornament.

Heading 2 Raleway 200 / 2.25rem / 1.2 line-height

Typography-driven hierarchy and clean proportion

Heading 3 Open Sans 300 / 1.5rem / 1.3 line-height

Content surfaces with mathematical precision

Heading 4 Open Sans 600 / 0.85rem / uppercase / 0.1em tracking

Section Labels and Category Markers

Body Open Sans 300 / 1rem / 1.7 line-height / 60ch max-width

Metro's typographic system draws directly from the International Typographic Style. Every font size, weight, and spacing value is deliberate. Text is set light and open at body sizes, creating a calm reading rhythm that contrasts dramatically with the bold display headings above.

dramatic contrast

Metro's typographic power is amplified against dark backgrounds. Ultralight white text on near-black surfaces produces the clean, luminous quality of transit signage.

Clean, typographic cards and controls let information take center stage. No shadows, no rounded corners. Just structure, color, and purpose.

Design Principle

Authentically digital

Rather than mimicking physical materials, Metro embraces its digital nature with purely screen-native elements. Flat color fields, scalable shapes, and resolution-independent type.

Principles

built on purpose

Every design decision in Metro serves a function. These principles guide the creation of interfaces that are clear, fast, and alive.

Authentically Digital

No imitation of physical materials. The interface embraces its screen-native nature with flat color fields, vector shapes, and resolution-independent typography.

Fast and Fluid

Interactions respond instantly. Transitions communicate spatial relationships and state changes, giving the flat interface depth through motion.

Do More With Less

Reduce to essentials. Every element earns its place on screen. Negative space is an active design component, not empty filler.

Pride in Craftsmanship

Precision in typography, alignment, and spacing. Every pixel is intentional. The beauty of well-set type on a clean canvas is the reward.

Effects & Details
