Table of ANSI/ASME Y14.1 Series Paper Sizes
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).
|ANSI A||216 × 279||21.6 × 27.9||8.5 × 11|
|ANSI B Ledger||432 × 279||43.2 × 27.9||17 × 11|
|ANSI B Tabloid||279 × 432||27.9 × 43.2||11 × 17|
|ANSI C||432 × 559||43.2 × 55.9||17 × 22|
|ANSI D||559 × 864||55.9 × 86.4||22 × 34|
|ANSI E||864 × 1118||86.4 × 111.8||34 × 44|
|ANSI F||711 × 1016||71.1 × 101.6||28 × 40|
|ANSI G||279 × 572–2286||27.9 × 57.2–228.6||11 × 22.5–90|
|ANSI H||711 × 1118–3632||71.1 × 111.8–363.2||28 × 44–143|
|ANSI J||864 × 1397–4470||86.4 × 139.7–447||34 × 55–176|
|ANSI K||1016 × 1397–3632||101.6 × 139.7–363.2||40 × 55–143|
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.
Unit of measurement
Unit of measurement is a definite magnitude of a value, defined and adopted by convention that is used as a standard for measurement of the same kind of value. Any other quantity of that kind can be expressed as a multiple of the unit of measurement.
mm stands for millimeter (American spelling) or millimetre (SI spelling) is the size of the unit of length in the metric system, that is the basis of the length measurement. 1 mm is equal to 0.1 cm.
cm stand for centimetre (international spelling as used by the International Bureau of Weights and Measures) or centimeter (American spelling) is a unit of length in the metric system, equal to one hundredth of a meter. cm being the International System of Units prefix for a factor of one per a hundred. cm is the base unit of length for cgs (centimetre–gram–second) system of units.
Inch (plural: inches, abbreviation: in or ″) is a unit of length in the imperial and United States customary systems of measurement, now formally equal to one per thirty six yard but usually understood as one per twelve of a foot. Derived from the Roman uncia, “inch” is also sometimes used to translate related units in other measurement systems. Traditional standards for the exact length of an inch have varied in the past, but since the adoption of the international yard during the 1950s and 1960s it has been based on the metric system and reckoned as exactly 2.54 cm.
