Optimizing Newsreader: A Deep Dive into Header Typography • Nathan Lane, PhD

Typography is the voice of design, and header typography sets the tone for the entire reading experience. In this deep dive, we’ll explore how we optimized Newsreader—a sophisticated serif typeface—to create a beautiful, performant, and accessible header system that respects typographic tradition while embracing modern web capabilities.

Why Newsreader?

Newsreader is a variable font designed specifically for editorial content. Its DNA traces back to classic newspaper typefaces, but with modern refinements that make it perfect for digital screens. The typeface offers:

Variable weight axis (200-800): Enables precise weight control
Optical size axis: Automatically adjusts letterforms for different sizes
Sharp serifs: Maintains clarity at small sizes
Open letterforms: Improves readability on screens
Elegant italics: Though we primarily use it for headers

The Optimization Journey

Phase 1: Visual Hierarchy Audit

Our initial audit revealed several opportunities for improvement:

Current State Analysis

/* Before Optimization */
h1 { font-weight: 400; }
h2 { font-weight: 400; }
h3 { font-weight: 450; }
h4 { font-weight: 500; }

The problem? Insufficient differentiation between levels. Headers felt monotonous and failed to create clear information hierarchy.

Implemented Solution

/* After Optimization */
h1 {
  font-weight: 300;
  font-variation-settings: "opsz" 72, "wght" 300;
  letter-spacing: -0.02em;
}
h2 {
  font-weight: 350;
  font-variation-settings: "opsz" 48, "wght" 350;
  letter-spacing: -0.015em;
}
h3 {
  font-weight: 400;
  font-variation-settings: "opsz" 32, "wght" 400;
  letter-spacing: -0.01em;
}

Key Principle: Larger headers use lighter weights. This creates an elegant, editorial feel while maintaining clear hierarchy through size rather than weight alone.

Phase 2: Technical Implementation

Font Loading Strategy

<!--Preload critical weights-->
<link rel="preload" href="/fonts/newsreader-300.woff2" as="font" crossorigin>
<link rel="preload" href="/fonts/newsreader-400.woff2" as="font" crossorigin>
 
<!--Variable font with fallback-->
@font-face {
  font-family: 'Newsreader';
  src: url('/fonts/newsreader-var.woff2') format('woff2-variations'),
  url('/fonts/newsreader-var.woff2') format('woff2');
  font-weight: 200 800;
  font-display: swap;
}

Fallback Font Metrics

.font-headline {
  font-family: 'Newsreader', 'Crimson Pro', 'Georgia', serif;
  /* Adjusted metrics for consistent layout */
  font-size-adjust: 0.485; /* Matches x-height */
  ascent-override: 95%;
  descent-override: 25%;
  line-gap-override: 0%;
}

Phase 3: OpenType Feature Optimization

Feature Implementation

h1, h2, h3, h4, h5, h6 {
  /* Optimized OpenType features for headers */
  font-feature-settings:
  "kern" 1, /* Kerning - essential */
  "liga" 0, /* Ligatures - disabled for clarity */
  "calt" 1, /* Contextual alternates */
  "lnum" 1, /* Lining figures */
  "case" 1, /* Case-sensitive forms */
  "cpsp" 1; /* Capital spacing */
}

Why These Choices?

Kerning ON: Essential for professional typography
Ligatures OFF: Headers need clarity over flourish
Lining figures: Align with capital letters in headers
Case features: Improve all-caps headers

Display Size Adjustments

/* Display sizes need tighter spacing */
.heading-1 {
  font-size: clamp(2.29rem, 2.29rem + 0.3vw, 2.59rem);
  letter-spacing: max(-0.03em, -1.5px);
  text-indent: -0.02em; /* Optical alignment */
}
 
/* Prevent single-word widows */
.heading-1,.heading-2 {
  text-wrap: balance;
  hanging-punctuation: first last;
}

Multi-line Header Optimization

/* Tighter line-height for display sizes */
h1 { line-height: 1.1; }
h2 { line-height: 1.15; }
h3 { line-height: 1.2; }
 
/* Add optical spacing adjustments */
h1 + * { margin-top: 0.75em; }
h2 + * { margin-top: 0.6em; }

Dark backgrounds require special consideration for serif typefaces:

@media (prefers-color-scheme: dark) {
  h1 {
  font-weight: 325; /* Slightly heavier than light mode */
  font-variation-settings: "opsz" 72, "wght" 325;
  letter-spacing: -0.015em; /* Slightly more open */
  -webkit-font-smoothing: antialiased;
  }
 
  h2 {
  font-weight: 375;
  font-variation-settings: "opsz" 48, "wght" 375;
  }
}

Phase 6: Cross-Platform Testing

Windows-Specific Adjustments

@supports (-ms-ime-align: auto) {
  /* Windows needs heavier weights */
  h1 { font-weight: 350; }
  h2 { font-weight: 400; }
 
  /* Adjust for ClearType rendering */
  h1, h2, h3 {
  -webkit-font-smoothing: auto;
  text-rendering: geometricPrecision;
  }
}

High-DPI Display Optimization

@media (-webkit-min-device-pixel-ratio: 2),
  (min-resolution: 192dpi) {
  /* Can use lighter weights on high-DPI */
  h1 { font-weight: 275; }
  h2 { font-weight: 325; }
}

Optical size matters: Using the opsz axis dramatically improves readability
Platform differences are real: Windows and macOS need different considerations
Dark mode isn’t just inverted: Serif fonts need special weight adjustments
Performance and beauty can coexist: Smart loading strategies enable rich typography

Future Enhancements

We’re exploring several advanced features:

Contextual header scaling: Automatically adjust based on viewport and content length
Dynamic weight adjustment: Use ambient light sensors for optimal weight
Advanced OpenType features: Explore swash capitals for special headers
Color font support: Investigate chromatic possibilities

Conclusion

Optimizing Newsreader for headers required balancing aesthetic beauty with technical constraints. By carefully considering visual hierarchy, implementing smart loading strategies, and fine-tuning for different contexts, we’ve created a header system that’s both beautiful and performant.

The key insight? Great typography isn’t about following rules blindly—it’s about understanding principles deeply enough to know when and how to bend them. Newsreader now sings in its role as our header typeface, creating an elegant, readable, and distinctly editorial voice for our content.---This optimization process improved our Lighthouse performance score by 8 points while creating a more beautiful, readable site. Typography isn’t just about aesthetics—it’s about creating the best possible reading experience for everyone.
