If you read about typography, three terms come up constantly: kerning, leading, tracking. They sound technical. They're actually simple — but each one does specific work, and learning the difference between them is the unlock that separates working with type from struggling with it.
This is the 2026 guide. What each term means, when to adjust each, and the rules working designers actually follow.
Quick answer: Kerning = space between two specific letters (pair-by-pair adjustment). Leading = vertical space between lines (line-height). Tracking = uniform letter-spacing across a word, paragraph or block. Kerning fixes specific visual problems. Leading affects readability and mood. Tracking changes the overall feel of typography. All three matter; getting them wrong is what makes typography feel amateur.
1. Kerning — Space Between Two Specific Letters
Kerning is pair-specific letter-spacing.
Type the word "AVOCADO" in a default typeface at large size. Look closely at the gap between "A" and "V". Then look at the gap between "O" and "C". The metric distance between the two letter pairs might be identical — but visually the "AV" gap looks bigger because the angled stroke of A and the angled stroke of V create extra negative space.
Good kerning compensates for the visual gap each specific letter combination produces. The designer tightens the space between A and V slightly (negative kerning) so the visual gap matches the visual gap between O and C.
Where kerning matters most:
- Wordmarks and logos — at large display sizes the kerning quirks of default typography become obvious
- Headlines — large headlines need hand-tuned kerning, especially in custom display fonts
- All-caps — capital letters have more dramatic visual gaps than lowercase; kerning is more visible
Where kerning matters less:
- Body text — at small sizes, individual letter-pair quirks aren't visible
- UI text — same reason; default kerning is fine
A good rule: any text at 36px or larger deserves a manual kerning pass. Wordmarks and logos always need one.
2. Leading — Space Between Lines
Leading (pronounced "ledding") is the vertical space between lines of text.
The term comes from physical printing: printers placed strips of lead between rows of metal type to add space between lines. Modern CSS calls it line-height. Same concept.
Measured baseline to baseline (from the bottom of one line of letters to the bottom of the next).
Different leading produces different moods:
- Tight leading (1.0–1.2× font size) — dense, editorial, magazine-like. Used for headlines and short blocks where space is at a premium.
- Comfortable body leading (1.5–1.7× font size) — the 2026 default for paragraph text on screens. Readable for long-form content.
- Loose leading (1.8× and above) — sparse, poetic, considered. Used for design-forward content where breathing room is part of the aesthetic.
For body text specifically:
- Cramped (1.0–1.2×) — makes paragraphs feel claustrophobic. Slows reading speed measurably. The single biggest readability killer in amateur design.
- 1.4× — passable but tight by modern standards
- 1.5–1.6× — the modern web default. Comfortable.
- 1.6–1.8× — premium / editorial. More white space, more breathable.
- 2× and above — unusual; works for poetry, large-quote display, or design-forward content
The single best move for amateur-looking typography is set leading higher. Most under-set body text needs 0.2–0.3× more leading than it has.
3. Tracking — Uniform Letter-Spacing Across a Block
Tracking is letter-spacing applied uniformly across a word, paragraph or block.
Unlike kerning, which adjusts specific letter pairs, tracking adjusts the space between every letter by the same amount.
- Positive tracking (looser) — letters are pushed apart. Used in all-caps headlines, luxury-brand wordmarks, and editorial display type to feel premium, considered, and breathable.
- Negative tracking (tighter) — letters are pulled together. Used in large display sans-serif headlines to feel modern, confident, and dense.
- Default tracking (zero) — the typeface's built-in spacing. Leave body text here.
Common applications:
- All-caps headlines — almost always need slight positive tracking. ALL CAPS WITH DEFAULT TRACKING LOOKS CRAMPED AND HARD TO READ. ALL CAPS WITH +5% TRACKING READS PROFESSIONALLY.
- Large display sans headlines — often benefit from slight negative tracking (–1% to –3%) to feel modern and tight. Apple, Linear, and most contemporary tech brands use this aggressively in headline type.
- Luxury wordmarks — heavily positive tracking (often +50–150%) so the brand name feels expansive and considered. Many fashion-house wordmarks use this technique.
- Body text — leave tracking at zero. Adjusting tracking on body text almost always makes it worse.
Quick Reference: When to Adjust Each
| Element | Kerning | Leading | Tracking |
|---|---|---|---|
| Body text (paragraph) | No — defaults are fine | Yes — 1.5–1.7× font size | No — leave at zero |
| Headlines (regular size) | Slightly — pair-check | Tighter than body (1.1–1.3×) | Negative for sans (–1 to –3%), positive for all-caps (+5%) |
| Display headlines (very large) | Yes — manual pair-tuning | Tight (1.0–1.2×) | Negative tracking common |
| Logos / wordmarks | Yes — always, by hand | N/A (single line usually) | Pair-by-pair via kerning, plus overall tracking pass |
| All-caps text | Yes | Slightly tighter than mixed-case | Positive tracking (+5–10%) |
| Captions | Defaults usually fine | Tight (1.3×) | Slight positive (+2–5%) for legibility |
The Three Most Common Mistakes
1. Cramped leading on body text
The single biggest amateur typography mistake. Body text set with leading at or below 1.2× the font size reads as dense and uninviting. Setting leading to 1.5–1.7× the font size fixes 90% of "this looks amateur" problems in body content.
2. Default kerning on logos
Setting a wordmark logo in a font's default kerning is rarely good enough. The bigger the type, the more visible default kerning quirks become — and a logo will appear at very large sizes (signage, hero, billboard). Every wordmark deserves a manual pair-by-pair kerning pass before it's locked.
3. Tightly tracked all-caps
ALL-CAPS TEXT SET WITH DEFAULT TRACKING LOOKS CRAMPED. The narrow distance between capital letters reduces legibility and increases visual density. Slight positive tracking (+5–10%) on all-caps headlines is the convention for a reason — it makes them readable.
How These Three Relate to Brand Identity
A well-built brand identity should specify all three:
- Kerning — handled at the wordmark/logo level (hand-tuned once, then locked); inherited from the typeface defaults elsewhere
- Leading — specified per hierarchy level (display, H1, H2, body, caption) in the brand guidelines
- Tracking — specified for any all-caps elements, large display headlines, and the wordmark itself
This is what separates documented brand typography from "use this font" instructions. The typeface choice is one decision; the kerning, leading and tracking rules are the system that makes the typeface work consistently across every surface.

When You're Outsourcing Typography Work
If you're commissioning brand typography or a logo wordmark, ask the designer to specify:
- The kerning approach for the wordmark (hand-tuned pair list)
- The leading values for each hierarchy level (display, H1, H2, H3, body, caption)
- The tracking values for all-caps headlines and the wordmark
- A type scale that documents the size relationship between hierarchy levels
A logo wordmark without a hand-tuned kerning pass isn't finished. A body-text system without explicit leading isn't documented. A brand-identity package without a tracking spec for all-caps headlines is incomplete.
DigitalPolo's brand identity service delivers full typography systems — display + body family selection, full hierarchy and scale, kerning specifications for the wordmark, leading and tracking rules for every hierarchy level — as part of every brand identity engagement.
Bottom Line
Kerning = space between two specific letters. Leading = space between lines of text. Tracking = uniform letter-spacing across a block.
Kerning fixes specific visual problems at large sizes. Leading affects readability and mood. Tracking changes the overall feel.
For body text: leading 1.5–1.7×, kerning and tracking at defaults. For display headlines: tighter leading, manual kerning, slight negative tracking. For all-caps: positive tracking (+5–10%). For logo wordmarks: always manual kerning, deliberate tracking choice.
Getting these three right is the unlock from amateur to working typography. Getting them wrong is what makes most amateur design look amateur, regardless of how well-chosen the typeface is.
That is the working designer's view of kerning, leading and tracking.
