How is a page defined in commercial printing?
A common mistake in pricing a booklet or catalog is counting the leaf as a single page. In commercial printing, pages are defined as each side of a leaf or a panel. They are counted just as you would in a book or magazine. Both the outsides and insides of the front and back of the cover count as pages too, for a total of four cover pages.
So, a booklet or newsletter that has four leaves, is actually considered an eight pager. The eight page 8.5 x 11 newsletter illustrated below is made up of two 17" x 11" sheets that are folded in half, collated, and then saddle stitched at the spine with two staples. Illustrations like this are shown on all product pages to help you find the right configuration you are looking for.
