Setting poetry without wrecking it
Prose is elastic. A paragraph is a stream of words poured into whatever measure it is given, and breaking it in a different place changes nothing a reader notices. Poetry is not that. Almost every reflex a prose typesetter has — justify it, rewrap the long line, tighten the spacing, fill the page — damages a poem.
The line is the unit
A line of verse ends where the poet decided it ends. That is not a layout outcome, it is the writing. Two rules follow, and neither bends.
Poetry is not justified. Justified setting stretches the word spaces on every line to force it out to the right margin. Verse lines are different lengths on purpose, so justification either does nothing or pulls the internal spacing apart to hit a margin that was never the point. Set poetry flush left, ragged right.
Nothing re-wraps, ever. A word processor wraps silently at whatever width it has, and a line that fits your screen may not fit the measure of a 5.5-inch page. If the setting treats a turned line as a new line, the poem now has a break the poet did not write, and nothing records that it was an accident. This is the commonest way a poetry book is damaged in production, and it is invisible unless you check the proof against your manuscript line by line.
A line too long for the measure is turned
When a line genuinely will not fit, it is turned: the remainder drops to the next line with a deliberate indent, so the reader sees it belongs to the line above. Conventions vary — a deep indent, or set flush right — but pick one and use it for the whole book, because an inconsistent turn reads as a stanza shape. Before accepting a turn, try the cheaper fixes: a slightly smaller body size, a wider text block, or a different trim.
The shape on the page is content
Indents, the gaps between stanzas, extra space inside a line to mark a caesura, stepped lines, lowercase where you expect a capital — in verse these are written, not styled. Anybody handling the book should treat them the way they treat the words: reproduce, do not tidy. Keep a clean reference copy and check the composed pages against it, because spacing vanishes quietly and no error is ever reported.
A poem should not break across a page
If a poem fits on one page, keep it on one page, even if that leaves the bottom of the previous page short. A reader who turns the page mid-poem loses the shape of it, which was half the point.
When a poem is too long to fit, break it between stanzas, never inside one if there is any alternative, and never leave one line stranded alone at the top or bottom. A two-page poem is better set across a facing pair so both halves are visible at once.
The break needs a visible convention, because a stanza gap that happens to fall at the foot of a page is indistinguishable from no gap at all. The usual solutions are to repeat the poem's title at the top of the continuation page, often followed by (continued), or to carry a small mark in the margin. Either is fine. Silence is not.
Line numbers
Long narrative poems, verse drama, facing-page translations and scholarly editions number the lines — conventionally every fifth line, in the outside margin — so a reader can cite a place. A collection of short lyrics does not need them, and adding them makes it look like a textbook.
The trim decides how long a line can be
The measure — the width of the text block — is the trim minus both margins, and it sets the longest line you can print unturned.
The inside margin is not negotiable downward: for a book up to 300 pages, allow 0.5 inches total, which satisfies both Amazon KDP and IngramSpark. Add a comparable outside margin and a 5.5-inch page leaves roughly 4.5 inches of line, while a 6-inch page leaves about 5. That is the whole reason poetry collections turn up at wider and squarer trims than novels: the extra inch buys lines that sit unturned.
Choose the trim from your longest poem, not your average one, and do it before you set anything, because changing it later re-turns every line in the book.

A collection has its own front and back matter
Poems usually start on a new page, with the title set like a small chapter opening. An epigraph sits under the title, a dedication to a person under that, both distinct from the body face so neither is read as a first line. Untitled poems are referred to by their first line, shown in square brackets in the contents.
Two more things readers expect. A contents page listing first lines as well as titles, because that is how people remember poems, plus an index of first lines at the back of an anthology or a long collection. And an acknowledgments page naming where individual poems first appeared, which is both a courtesy and often a condition of the original publication.
The ebook problem is severe
A reflowable EPUB re-wraps text at whatever size the reader chooses. That is the feature, and for a poem it is destruction: long lines break at arbitrary words, and the break moves when the reader changes the type size.
You cannot prevent it, so handle it deliberately. Mark every line as a line rather than letting them run together, and set a hanging indent so a line that turns reads as a turn rather than as a new line. Keep stanza spacing as real structure, not blank lines. Then open the file on a phone at a large type size — the worst case — and watch what your longest poem does.
Some publishers set poetry as fixed layout for exactly this reason, accepting that the page stops adapting to the reader. It is a real trade, and worth reading about before you take it.
