An en space is a typographic space traditionally equal to half an em, though its exact visual width depends on the typeface and composition system. It is often used where a normal word space is too narrow but an em space would be too dramatic. In poetry, an en space can subtly separate phrases, speakers, or paired images without creating a full break in the line. Its measured distance can support a poem's visual rhythm while preserving an overall sense of connection.

An "en space" (or nut space) is a typographical unit of measurement equal to half an em space, typically matching the width of a capital letter "N". In poetic typesetting, en spaces are frequently used to separate small layout elements, create precise indents for alternating rhymed lines, or space out characters in titles. Understanding the distinction between an em space and an en space helps students appreciate subtle typographic pacing: an em space creates a heavy, noticeable pause, whereas an en space offers a clean, moderate breath without disrupting textual continuity. Related terms include em space, thin space, en dash, and kerning.
