Every engineering drawing must have a title block. [13] [14] [15] The title block (T/B, TB) is an area of the drawing that conveys header-type information about the drawing, such as: Drawing title (hence the name "title block") Drawing number; Part number(s) Name of the design activity (corporation, government agency, etc.)
ISO 7200, titled Technical product documentation - Data fields in title blocks and document headers, is an international technical standard defined by ISO which describes title block formats to be used in technical drawings.
A size chart illustrating the ANSI sizes. In 1992, the American National Standards Institute adopted ANSI/ASME Y14.1 Decimal Inch Drawing Sheet Size and Format, [1] which defined a regular series of paper sizes based upon the de facto standard 8 + 1 ⁄ 2 in × 11 in "letter" size to which it assigned the designation "ANSI A".

Typical fields in the title block include the drawing title (usually the part name); drawing number (usually the part number); names and/or ID numbers relating to who designed and/or manufactures the part (which involves some complication because design and manufacturing entities for a given part number often change over the years due to ...

A1, A2, A3, A4 and non-ISO sizes as GOST 3450-60 formats. A standard for technical drawings from 1960, GOST 3450, [15] introduces alternative numeric format designations to deal with very high or very wide sheets. These 2-digit codes are based upon A4 = "11": The first digit is the factor the longer side (297 mm) is multiplied by and the second ...
