Type rules cap height and leading

Summary

A type-rules page: usage rules at left, beside a "BOW" diagram calling out matched cap height and equal leading, and a Medium Yellow Detroit Film Theatre ticket showing the type in use.

Visual description

Charcoal background with the thin olive top band. "TYPE" sits top-left in cream sans over three short blocks: use DIA Mix for titles and subheads (pair only in uppercase, match cap height), use Neue Haas Grotesk for body, and use justified paragraphs for subhead info. The right side shows a large cream "BOW" specimen in mixed serif-and-sans caps inside a red annotation frame labeled "same cap height" and "equal leading." Below it, a Medium Yellow ticket mockup reads "GENERAL ADMISSION JANUARY 8 2022 $9.50 2.00 PM" with a QR code and a repeated "DETROIT FILM THEATRE" wordmark band in charcoal. The standard footer runs below.

Key takeaway

Using a single short word ("BOW") with measurement annotations to teach the two non-negotiable pairing rules (matched cap height, equal leading) at a glance. Following it immediately with a real ticket grounds the abstract rule in an artifact.

Reuse notes

A clear typographic-rules page that demonstrates rather than lists. The annotated specimen is reusable for teaching any mixed-typeface alignment rule. Pair with one real application so the rule reads as practical, not theoretical.
