What Poster Designer does and how it behaves

A poster is read from across a room before it is read up close, so its headline has to win from a distance while its details survive a close look. This tool builds a poster from the three things that decide that outcome: a standard poster size template, text levels that establish a clear hierarchy, and an image placed in its own region of the layout. The surprise for most first-time users is that the size template is a design decision, not a final step - its proportions shape every layout choice that follows.

How the result is produced

Size templates set the frame

Design starts from a standard poster size template, and the template fixes the proportions of the page. Those proportions constrain how much text fits and where an image can sit, so the size choice comes first, not last. Moving the same content to a different template changes the frame's shape, and the layout has to be re-judged for the new proportions rather than carried over unchanged.

Hierarchy orders the type

Text is set in levels rather than placed as one block: a headline that carries the message, a supporting level beneath it, and small detail text. Size and weight separate the levels so the structure is visible at a glance and from a distance. Image placement is a separate concern, with the picture holding its own region of the layout instead of sharing space with the type.

Good uses

Announcing a local event - a gig, talk, sale, or opening - with one strong headline and the essentials (date, time, place) set out so they are easy to find.
Producing a wall poster at a real paper size when the print shop needs a standard format and a social-media graphic or document page will not print at poster dimensions.
Building a layout around a specific photo, where the image needs a deliberate position and the text has to be sized to the space that remains.

Limits and checks

A layout is not portable across templates. Different poster sizes have different proportions, so text that fits a tall, narrow template can overflow a shorter, wider one. Decide the print size before finalizing the copy, then treat any later size change as a re-layout.
Hierarchy is a size relationship, not a font choice. If every text level ends up close to the same size and weight, the poster flattens into equal-weight type with nothing standing out, and the hierarchy the tool is built around quietly disappears.
The on-screen view is seen at close zoom; the printed poster is seen from meters away. Detail text that looks fine in the on-screen view can be unreadable at arm's length, so the smallest text level should carry only what truly needs to be on the poster.

Common questions

Which template size should I pick?

Match the template to the paper the print shop will actually print on, and to the distance the poster will be read from. A larger size is not a magnified version of a smaller one - it is a different set of proportions, so text and image positions need re-judging rather than automatic scaling. When in doubt, ask the printer what sizes they accept.

How much text belongs on a poster?

Less than most people expect. A poster carries a headline, a line or two of support, and the essential details: date, place, price, contact. If the content needs paragraphs, it is a flyer or a page, and forcing that much copy through a poster layout is the fastest way to flatten the hierarchy that makes a poster work.
