“e” is the most common letter in the English language, which means it’s also the letter under the most pressure. Every tiny flaw in its curve, every awkward angle in its crossbar, gets repeated hundreds of times across a single page of text, magnified by sheer frequency. This is the fifth entry in our glyph series, following “a,” “b,” “c,” and “d.” Today, we’re taking apart the letter you’ll see more than any other on this page.

A Short History of “e”

“e” traces back to the Phoenician letter he, which is believed to have represented a person with raised arms, possibly in a gesture of joy, prayer, or calling out — historians differ on the exact meaning, but the image of a figure with arms up is the one that tends to stick. When the Greeks adopted the letter, they renamed it epsilon and straightened its shape considerably, turning the human figure into a more geometric form with horizontal strokes stacked on a vertical spine — essentially the ancestor of the capital “E” we still use.

The Etruscans and Romans carried the letter forward largely unchanged in its capital form, which is part of why capital “E” has stayed so visually stable for roughly 2,500 years. Lowercase “e,” on the other hand, went through a more interesting transformation. During the handwritten, cursive-influenced writing of the early medieval period, scribes began closing up the open, angular Greek and Roman form into a rounder shape, and by the time the Carolingian Renaissance standardized lowercase letterforms in the 8th and 9th centuries, “e” had become the rounded shape with a horizontal crossbar that we recognize instantly today.

Interestingly, some early medieval scribal traditions experimented with a slanted or “epsilon-style” lowercase e — a more open, less enclosed shape — but the closed, crossbar-through-the-middle version won out because it was faster to write in a single continuous pen stroke and easier to distinguish from “c” and “o” at a glance.

Anatomy of a Lowercase “e”

Lowercase “e” is deceptively complex for a letter most people never think twice about. Its main body is a rounded bowl, similar in basic structure to “c” and “o,” but with a horizontal stroke — the crossbar — cutting through the middle and creating a small enclosed space called the counter.

The angle of the crossbar is one of the most quietly important decisions in the whole letter. A perfectly horizontal crossbar reads as clean and modern; a slightly upward-angled crossbar — a detail borrowed from calligraphic pen strokes — gives the letter warmth and a sense of handwritten motion. Too steep an angle, though, and “e” starts to look unstable or even like a different letter entirely at small sizes.

Just like “c,” lowercase “e” has an aperture — the opening at the bottom right where the bowl doesn’t fully close. This opening needs to be wide enough to keep the counter from clogging with ink (or pixels) at small sizes, but narrow enough that the letter doesn’t collapse visually into a “c.” Because “e” combines a closed counter, an open aperture, and a crossbar all in one small shape, it’s often considered one of the most structurally busy letters in the entire lowercase alphabet, despite looking simple at a glance.

“e” is closely related to “c” and “o” in terms of curve tension and to “a” in terms of overall bowl proportion, so all four letters typically get checked against each other repeatedly during the design process.

Designing the Letter From Scratch

Because “e” appears more often than any other letter in English text, many type designers treat it as one of the first letters drawn after “o” and “n” — the three letters most commonly used as a baseline reference for stroke weight, x-height, and curve tension across an entire typeface.

The process usually starts with the bowl, built on the same curve logic already established in “o” and “c.” From there, the crossbar gets added, and this is where most of the real design decisions happen. Designers experiment with the crossbar’s height — usually positioned right around the middle of the x-height, though shifting it up or down changes the letter’s visual weight distribution — and its angle, deciding how much upward tilt (if any) to give it.

The aperture gets tuned next, in direct comparison with “c,” since both letters share the challenge of keeping an open curve legible without collapsing into “o.” Many designers test “e” specifically in common short words — “the,” “he,” “were” — because these appear so frequently that any awkwardness in the letter becomes obvious almost immediately once it’s set in real running text rather than viewed in isolation.

Because of how often “e” repeats on a page, designers also pay close attention to how it looks when many copies appear close together in a paragraph. A subtle flaw that’s invisible in a single large specimen can become a distracting visual rhythm once it’s repeated fifty times in a paragraph, so “e” often goes through more rounds of small-size proofing than almost any other lowercase letter.

Unique Facts About “e”

“e” is the most frequently used letter in the English language by a wide margin, appearing in roughly 12% of all letters in typical English text — which is part of why it was assigned the shortest code in Morse code, a single dot, and why it’s typically the highest-value single-tile deduction to lose in word games like Scrabble that rely on English letter frequency.

Because it’s used so often, “e” is also one of the first letters cryptographers look for when trying to break a substitution cipher, since its frequency tends to stand out clearly even in scrambled text.

In type design specifically, “e” is sometimes called a “trap letter” for beginner type designers, because its combination of bowl, aperture, and crossbar hides more structural decisions than its simple appearance suggests — many first-time typeface designers underestimate how much time “e” actually requires compared to visually busier-looking letters like “g” or “k.”

“e” in Popular Fonts

In Garamond and other old-style serifs, “e” carries a distinctly angled crossbar, a direct echo of broad-nib pen calligraphy, along with diagonal stress that thickens and thins the bowl the way a real pen naturally would. Helvetica levels the crossbar out almost perfectly horizontal and keeps the bowl mechanically even, contributing to its neutral, engineered character. Futura opens the aperture wide and keeps the bowl close to a true circle, with a crossbar set at a precise, almost mathematical angle that matches its geometric design philosophy.

In script and handwriting fonts, “e” is often drawn with a looping counter or an exaggerated crossbar stroke that flows directly into the connecting stroke of the next letter, since “e” appears so often in cursive writing that its shape has a huge influence on how natural an entire script typeface feels in actual words.

Summary

Lowercase “e” hides real complexity behind an unassuming shape — a bowl, a crossbar, an aperture, and a counter, all balanced precisely enough to survive being repeated more often than any other letter in the English language. From a Phoenician figure with raised arms, through a straightened Greek epsilon, to the rounded, crossbar-through-the-middle form scribes settled on over a thousand years ago, “e” has quietly become the letter every typeface lives or dies by, simply because of how often it shows up.
