Ligatures in Display Type: When Connecting Letters Adds Value

Beyond the Standard Ligatures

Every decent typeface includes standard ligatures — the fi, fl, ff, ffi, ffl combinations that prevent the dot of the i or the ascender of the l from colliding with the hook of the f. These are housekeeping. They're on by default and they solve a technical problem.

The ligatures I find interesting are the discretionary ones: the historically motivated combinations like ct and st, the stylistic alternates that connect letters at their terminals, the custom ligatures that a type designer built as expressive options rather than corrections.

In body text, these are subtle touches. In display work and logotypes, they're compositional elements.

What a Ligature Does

At its core, a ligature does one of two things: it solves a collision problem, or it creates a visual connection between letters that implies they belong together.

The second purpose is the interesting one. When two letters share a stroke — when they connect physically — the eye reads them as a unit within the word. This creates rhythm within the letterform sequence, interrupting the visual flow with moments of binding.

In a logotype, a well-placed ligature is a small surprise. The viewer sees the word, then sees the connection, then sees the word again differently. That dual reading creates engagement.

How I Approach Ligatures in Logo Work

When I'm developing a wordmark, I look for ligature opportunities in the same way I look for negative space opportunities: as a potential design event, not a default feature.

I ask: do any adjacent letters have natural connection points? Where do terminal strokes reach toward the next letter? Where do two ascending or descending elements create natural overlap?

Then I sketch the possible connections and evaluate. A ligature has to feel motivated — the connection should look like it was meant to happen, not forced. An unnatural ligature reads as a mistake.

The Letters That Ligature Most Naturally

Some letter combinations invite ligatures more than others:

Adjacent letters sharing horizontal strokes (T-E, H-I, E-T) can connect across their crossbars. Letters with descenders and ascenders that happen to be adjacent in a word can link vertically. Round letters (O, C, G, Q) can blend into adjacent curves.

Script and calligraphic typefaces have ligature potential built into their design — the flowing strokes naturally extend toward adjacent letters. Geometric and grotesque typefaces require more deliberate design to create ligatures that feel native to the letterforms.

Discretionary Ligatures in Print

In high-quality print work — book design, editorial work, premium marketing materials — discretionary ligatures add a layer of typographic refinement that rewards attention. Headlines set with all available ligatures have a different texture from the same text set without them.

This is micro-typography: details that most readers won't consciously notice but that collectively give the typography a crafted quality. Like optical kerning or precise leading, ligatures in print work are part of the invisible craft that distinguishes thoughtful typesetting from automatic typesetting.

When Not to Use Them

Ligatures in body text can interrupt reading if they're too visually prominent — the connection becomes a distraction rather than an enhancement. Save the expressive ones for display sizes.

Also: never use ligatures in contexts where letters might be read individually — monospaced text, code, tracking numbers, serial numbers. The ligature collapses individual character identity, which is sometimes a feature and sometimes a very serious problem.

Know what you're connecting and why. Intentional ligature use is sophisticated. Accidental ligature use is a production error.
