In drafting, paper size refers to the specific dimensions of the paper on which the drawings are created or printed. The choice of paper size depends on various factors, including the nature of the project, the intended use of the drawings, and the drafting standards followed. Here are some commonly used paper sizes in drafting:

ANSI Sizes: The American National Standards Institute (ANSI) has established a series of standard paper sizes for technical drawings. The ANSI sizes include:

These sizes are widely used in North America.

ISO Sizes: The International Organization for Standardization (ISO) has defined a set of paper sizes known as the ISO series. The ISO sizes include:

The ISO sizes are commonly used in many parts of the world, including Europe and Asia.

Architectural Sizes: For architectural drawings, specific paper sizes are often used. The most common architectural size is 24 x 36 inches, also known as Arch D. Other architectural sizes include: 

Custom Sizes: In addition to standard paper sizes, drafting may involve the use of custom or non-standard paper sizes based on specific project requirements. These custom sizes are often used for large-scale drawings, specialized applications, or unique design needs.

When selecting a paper size for drafting, it's important to consider factors such as the complexity and scale of the drawing, the level of detail required, and the available printing or reproduction options. Additionally, it's essential to adhere to the relevant drafting standards or guidelines prescribed by the industry or organization to ensure consistency and compatibility with other drawings and documents.
