Freedam's take

I love seeing civic design systems treat a city's visual legacy with such clarity. The Chicago Design System lays out its foundational civic marks, from the historic star geometry down to the Big Shoulders municipal typeface. Seeing how they engineered an OpenType ligature where typing CHISTAR renders the official star glyph feels wonderfully thoughtful for everyday staff. The structure also thoughtfully accounts for department lockups like CHI311 and community partnerships across pride and national flags.

Civic, practical, and systematic guidance designed for public employees and community collaborators.

What I noticed

  1. The typography guidelines specify Big Shoulders as the municipal typeface in all capitals and explain that typing CHISTAR triggers an OpenType discretionary ligature to produce the municipal star glyph.123
  2. The Public Mark documentation covers horizontal, stacked, and shortened CHI variants, along with department lockups like CHI311 and inter-agency pairings separated by vertical dividing lines.456
  3. Color palettes are split into Primary, Secondary, Tertiary, Background, and States categories with labeled HEX codes and color names.78
  4. A banner at the top of the homepage displays a maintenance disclaimer indicating the site is not actively maintained.9

Numbers refer to the screenshots above.

What I could not see

  • Direct asset download packages, search functionality, and editable presentation templates could not be verified on the captured screens.

Ideas to borrow

  1. Civic organizations can embed municipal symbols directly into custom typefaces via OpenType ligatures to make brand graphics effortlessly accessible in plain text fields.2

Quick answers

What is the official typeface of the City of Chicago?

Big Shoulders is designated as the municipal typeface for headings, titles, banners, and posters, complemented by Roboto and Lora for secondary body text.110

How do you create the Chicago star symbol in text?

In supported design tools with discretionary ligatures turned on, typing CHISTAR in all capital letters using the Big Shoulders typeface generates the Chicago star glyph.23
