Table of ANSI Paper Sizes (mm, cm, inch) 📋

Here is a Table of The ANSI/ASME Y14.1 Series Drawing Paper Sizes. These include ANSI A, ANSI B, ANSI C, ANSI D, ANSI E, ANSI F, ANSI G, ANSI H, ANSI J, and ANSI K. Standard Dimensions or Length and Width of Paper in ANSI Series in unit of measurements in mm (millimeter), cm (centimeter), and inch (inches).

Size F does not continue the alphabetic series, because it does not exhibit the same aspect ratios. Sizes G, H, J and K are roll formats. G size is 22 1/2 inch (571.5 mm) high, but variable width up to 90 inch (2286 mm) in increments of 8 1/2 inch. Such sheets were at one time used for full-scale layouts of aircraft parts, wiring harnesses and the like, but today are generally not needed, due to widespread use of computer-aided design (CAD) and computer-aided manufacturing (CAM).

The American National Standards Institute adopted ANSI/ASME (American Society of Mechanical Engineers) Y14.1 Decimal Inch Drawing Sheet Size and Format which defined a regular series of paper sizes based upon the de facto standard in “letter” size which it assigned “ANSI A”. This series also includes “ledger” or “tabloid” as “ANSI B”. This series is nearly similar to the ISO 216 standard of A Series paper sizes in that cutting a sheet in half would produce two sheets of the next smaller size. Unlike the ISO standard, however, the arbitrary aspect ratio forces this series to have two alternating aspect ratios. ANSI/ASME Y14.1 has been revised or updated in 1995, 2005 and 2012. It has an accompanying standard ANSI/ASME Y14.1M that defines metric drawing paper sizes.
