About Paper Sizes Reference
This reference lists 50 standard paper sizes: the full ISO 216 A and B series (A0–A10, B0–B10), the C series envelopes (C0–C10), North American formats from Letter, Legal and Tabloid to the ANSI A–E drawing sizes, plus photo prints, business cards and common book trim sizes.
Each size is shown in millimeters, inches and pixels, and the pixel column is live: pick 72, 96, 150, 300 or 600 DPI — or type a custom value — and every dimension is recalculated instantly. A portrait/landscape toggle flips all measurements, which is handy when checking landscape A4 in inches or Letter at 300 DPI for print-ready artwork.
Category chips narrow the table to one family, a search box finds a size by name, and clicking a row opens a scaled preview of the sheet’s proportions with its exact mm, inch, pixel and aspect-ratio values, each copyable with a click.
