Clean UI Blueprint

A concise spec sheet of typography, colors, and radii for minimal UI

A practical styling blueprint providing concrete values for typography, grayscale hierarchy, icon sizing, and corner radii. It distills the clean, minimal SaaS look into five straightforward rules based on the Alpaca Labs interface. It serves as a fast reference for styling modern dashboards and apps without guessing design tokens.

How it works

  • Use SF Pro in regular and medium with -0.15px letter spacing
  • Keep type to 12px, 13px, 14px, and 24px
  • Build hierarchy with #292929, #5D5D5D, and #9E9E9E
  • Size icons at 14px for navigation and 20px for cards
  • Use 8px navigation, 16px cards, and rounded pill CTA radii

What it's for

  • Establish baseline design tokens for a new SaaS product
  • Standardize typography and grayscale hierarchy across app views
  • Refine border radii and icon scaling for a polished, minimal aesthetic

Key points

  • SF Pro font pairing in regular and medium weights with -0.15px letter spacing
  • Restricted type scale using 12px, 13px, 14px, and 24px
  • Three-tier grayscale hierarchy using #292929, #5D5D5D, and #9E9E9E
  • Standard icon dimensions of 14px for navigation and 20px for cards
  • Specific corner radii: 8px for navigation, 16px for cards, and full pill rounding for CTAs
