Gutter
noun · typography & page layout
What it is
The gutter does the quiet work of keeping columns legible. Without it, the last word of one column and the first word of the next would sit close enough that the eye could jump the gap mid-line and read across two unrelated columns. A gutter wide enough to signal "stop here, return" — but no wider than necessary — is what lets multi-column text be scanned as separate streams.
The word carries two related senses. In a typographic grid, the gutter is the vertical space between columns; designers tune it in tandem with column width and measure. In bookbinding, the gutter is the inner margin running down the spine, deliberately set wider than the outer margin so text is not swallowed by the curve of the binding when the book is opened.
Etymology
"Gutter" enters print terminology by analogy with the architectural gutter — a channel that carries water away. In letterpress, the gutter was the furniture (blank spacing material) locked between columns in the forme. Josef Müller-Brockmann treats the gutter as an explicit grid parameter in Grid Systems in Graphic Design (1981), giving it the role of the unit that ties column width to overall page rhythm.
Examples in use
"Widen the binding gutter to 18 millimetres — the proof is disappearing into the spine." A web developer writing CSS Grid sets column-gap, which is the gutter by another name. In a newspaper, narrow gutters with hairline column rules pack more stories onto the page while keeping them visually distinct.
