Magazine ad sizes
Three measurements govern every print ad. Trim is the page's final cut size. Bleed is the extra image, conventionally an eighth of an inch, that runs past the trim so the cut never shows white. Live area is the inner safety zone where anything you cannot afford to lose must sit. Confuse them and the printer decides your layout.
| Unit | What it is | Typical use |
|---|---|---|
| Full page (bleed) | Trim size plus bleed on all four edges | Brand work, launches, covers |
| Full page (non-bleed) | Image floats inside margins, no bleed | Budget full-page creative |
| Spread | Two facing pages; art crosses the gutter | Category-dominance statements |
| Half page, horizontal | Bottom or top half of the page | Response ads with wide art |
| Half page, vertical | One column-side half | Outside-edge visibility |
| Third page | Vertical column or horizontal band | Editorial-adjacent presence |
| Quarter page | One quadrant | Entry-level and local schedules |
Why we print no inch table
Because there is no universal one. Trim sizes differ by title and change when publishers cut paper costs, and a dimensions table copied from a blog is how ads get rejected at materials close. The only authoritative dimensions are in the title's current media kit spec page[2], usually one PDF page listing every unit with trim, bleed and live measurements. Request it in Step 01, hand it to your designer unedited, and have them build to the PDF/X exchange standards the industry actually specifies.[1]
File-side requirements: artwork specs. What each unit costs: full, half, quarter. Briefing the designer: Step 08.
