概要
Letter paper measures 8.5 × 11 inches and remains the default office and school format across North America. It is the page size most people mean when they say printer paper, copy paper, or standard notebook paper.
For PaperGens, Letter is also the anchor size behind many of the site’s most important printable templates. It is the best starting point for ruled notes, graph paper, blank pages, and general classroom handouts before you branch into Legal, A4, or specialty card sizes.
