Kerning and Spacing a Full Typeface: The Invisible Work That Takes Longer Than Drawing the Letters¶

Drawing a typeface's individual letterforms is visible, appreciable creative work - anyone looking at a finished glyph can recognize the design decisions in its shape. Spacing each letter correctly, and then kerning specific letter pairs that need individual adjustment beyond the default spacing, is invisible, unglamorous work that most people outside type design never consciously notice - and it routinely takes longer than designing the letterforms themselves, because it has to be evaluated across an enormous number of real-world letter combinations, not just in isolation.

Spacing Is Set Once Per Letter, but Tested Across Nearly Infinite Combinations¶

Each individual letter gets a base spacing value - how much space sits to its left and right - but that single value has to work reasonably well across every possible combination that letter will ever appear in, next to every other letter in the alphabet, in real words a designer can't fully predict in advance. A spacing value that looks fine next to one specific neighboring letter can look cramped or loose next to a different one, and finding a single value that works acceptably across this enormous range of combinations is a genuinely harder optimization problem than it initially appears.

Kerning Handles the Specific Pairs Default Spacing Can't Solve¶

Even with well-chosen base spacing, certain specific letter pairs - a capital 'A' next to a capital 'V,' for instance, where their diagonal strokes create unusual empty space between them at default spacing - need individual kerning adjustments beyond what a single spacing value can account for. A complete, professional typeface can require kerning adjustments for hundreds or even thousands of specific letter pairs, each evaluated and adjusted individually, which is a substantial, detail-oriented undertaking distinct from and in addition to the base spacing work.

Real Word and Sentence Testing Reveals Problems Isolated Letter Review Misses¶

Reviewing spacing and kerning by looking at isolated letter pairs catches many issues, but real problems often only become visible in the context of actual words and full sentences, at various sizes, where the cumulative effect of many adjacent letters interacts in ways a pairwise review doesn't fully predict. Setting real, representative sample text - not just the alphabet in sequence - and reviewing it at multiple sizes is an essential, and often underestimated, part of properly finishing spacing and kerning work.

Rushing This Stage Undermines Everything the Letterform Design Accomplished¶

A typeface with beautifully drawn individual letterforms and rushed, inconsistent spacing will read as unpolished and unprofessional in actual use, regardless of how strong the individual letter designs are - because spacing and kerning problems are exactly the kind of thing that registers as "something feels off" to a reader even when they can't articulate why, similar to the way poor typographic habits undermine an otherwise strong graphic design layout. This makes properly completing spacing and kerning work a genuine requirement for a typeface to actually perform well, not an optional polish step that can be shortened under deadline pressure without real cost.

FAQ¶

How much of a total type design project's time is typically spent on spacing and kerning?
It varies by typeface complexity and character set size, but it's common for this stage to take as long as or longer than the initial letterform design phase, which surprises many people new to type design who assume the visible, creative drawing work is the larger time investment.

Are there tools that can automate or speed up kerning?
Software tools can generate an initial automated kerning pass and flag pairs likely to need manual adjustment, which speeds up the process, but final review and adjustment by a human eye, testing real words and sentences, remains necessary for professional-quality results.

Does a typeface with a smaller character set require proportionally less spacing and kerning work?
Generally yes, since fewer characters produce fewer possible pairings to evaluate and adjust, though the relationship isn't perfectly linear since a smaller character set can still require careful attention to the specific pairs it does include.
