A brochure unfolds
A folded brochure is useful when a subject can be broken into a small set of panels. Think about the cover, the first reveal and the fully open piece. Panel order matters as much as the layout on each panel.
A booklet turns the page
Programs, short guides and company introductions often need a sequence. A booklet gives each section a page or spread, helping the reader move through the material. Page count, binding and the relationship between cover and inside paper should be discussed early.
A catalog helps people compare
A catalog needs a repeatable system for product names, photography and useful details. Consistent image proportions and information hierarchy make a larger collection easier to browse. Start with the product content before committing to the final page count.
Edit before you expand
More space is not a reason to add more words. Organize the content first, then choose the format that lets someone understand it with the least effort. Keep the artwork flexible until the paper, fold or binding setup is confirmed.
