Look closely and you’ll notice something odd: lowercase “g” doesn’t have one standard shape the way most letters do. Depending on the font, it might have a simple open tail, or it might loop dramatically below the baseline into something that looks almost like a figure eight. Few letters in the Latin alphabet show this much structural variation while still being read as the exact same character.

A Short History of “g”

“g” has one of the more unusual backstories in the alphabet because, unlike most letters, it was invented rather than inherited. The Romans originally used “C” for both a hard “k” sound and a hard “g” sound, since early Latin didn’t distinguish clearly between the two. That created constant ambiguity, so at some point during the early Republic era, a modification was made: a small stroke was added to “C” to create a new letter dedicated specifically to the voiced “g” sound. That new letter was “G,” and it was inserted into the Latin alphabet in the position previously held by the Greek letter zeta, which Latin didn’t need at the time.

Because “G” was essentially “C” with an addition, the two letters have always shared close visual DNA — you can still see the family resemblance in the curved bowl both letters carry today.

Lowercase “g” took a genuinely strange turn during the medieval period. While most lowercase letters simplified and rounded out from their capital ancestors in fairly predictable ways, “g” split into two distinct handwritten traditions. One tradition kept a single-story form, closer to the capital shape with an open tail curling below the baseline. The other developed into a double-story form, where the descender curls back up into a closed or nearly closed loop, creating that figure-eight-like silhouette. Both traditions survived side by side for centuries and were eventually absorbed into standard typography, which is why modern fonts still split down these two lines today.

Anatomy of a Lowercase “g”

Because “g” comes in two structurally different versions, it needs two separate anatomical breakdowns.

The single-story g consists of a rounded bowl, similar in basic shape to “a” or “o,” attached to a descender — a curved tail that drops below the baseline and typically hooks or curls slightly at the bottom. This version looks closer to handwriting and tends to feel more casual or approachable.

The double-story g (sometimes called a “looped g”) is considerably more complex. It has an upper bowl, similar to a single-story “g,” but instead of a simple hooked tail, the descender loops back on itself to form a closed or partially closed lower counter — a second enclosed space beneath the first. This creates a shape with two distinct rounded compartments stacked vertically, connected by a narrow link or neck.

The link is the most technically demanding part of a double-story “g” to draw. Too thick, and the letter looks clumsy and heavy at the middle. Too thin, and it becomes fragile-looking or can disappear entirely at small print or screen sizes. Getting the proportion between the upper bowl, the link, and the lower loop right is considered one of the more advanced challenges in lowercase letter design.

Designing the Letter From Scratch

Before a type designer draws a single curve, they have to make a decision most other letters don’t require: single-story or double-story. This choice is rarely arbitrary — it usually gets set by the overall personality of the typeface. Geometric, humanist, and many contemporary sans-serif designs often lean toward single-story g’s because they feel cleaner and more casual. Traditional serif and editorial typefaces tend to favor the double-story form because it carries more historical, literary weight.

For a single-story g, the process starts with the bowl, drawn using the same curve logic as “a” and “o,” then extended into a descender. The trickiest part is the hook at the bottom of the tail — too tight a curl and it looks fussy, too loose and the letter feels unfinished or like it’s trailing off mid-stroke.

For a double-story g, designers usually draw the upper bowl first, matching it to “o” and “a” for consistent curve tension. Then comes the hardest part of the entire letter: the link connecting the upper bowl to the lower loop. This gets tested extensively at multiple sizes, since a link that looks elegant at large display sizes can clog into an unreadable blob in small body text. Many designers build several link variations before settling on one that survives both scales.

Whichever form is chosen, the descender depth needs to match other descending letters in the typeface — “j,” “p,” “q,” and “y” — so the whole line of text sits with a consistent rhythm below the baseline.

Unique Facts About “g”

The double-story “g” is widely considered one of the hardest single letters to draw well in an entire typeface, and type designers sometimes cite it as a genuine skill benchmark — a well-executed double-story g is often treated as a sign of a mature, well-considered typeface.

Because of the loop’s complexity, some early digital and low-resolution rendering systems struggled specifically with double-story g’s, which occasionally clogged or blurred at small screen sizes before font hinting technology improved enough to handle the shape reliably.

“g” is also one of the few lowercase letters where the two variant forms aren’t considered stylistic alternates the way a swash capital might be — they’re both fully standard, interchangeable shapes representing the exact same letter, which is fairly unusual in the Latin alphabet.

“g” in Popular Fonts

Garamond and most classic old-style serifs use the double-story form, with a distinctly calligraphic link and a lower loop that echoes broad-nib pen strokes. Helvetica uses a single-story g with a simple hooked descender, keeping the letter clean and consistent with its minimal, engineered design philosophy. Futura also opts for single-story, with an almost perfectly circular bowl matching the rest of its geometric letterforms.

In script and handwriting fonts, “g” is almost always single-story, since the looping, connected nature of cursive writing naturally produces a simple curling tail rather than a closed double loop — though some highly decorative or vintage-inspired scripts do include an exaggerated double-story g purely for stylistic flourish.

Summary

Lowercase “g” is proof that not every letter in the alphabet settled on a single agreed-upon shape — its single-story and double-story forms both trace back to competing medieval handwriting traditions that never fully merged, and both survive today as fully legitimate, interchangeable versions of the same letter. Between its invented origin as a modified “C” and its uniquely demanding double-story anatomy, “g” carries more structural complexity than almost any other lowercase character.
