US Series



Belonging to the ANSI series, the ANSI B paper size stands as a testament to standardization and uniformity in the world of print. This particular size, measuring 11 x 17 inches or 279 x 432 mm, is part of the American National Standards Institute (ANSI) series that is widely recognized and utilized across various industries.

The ANSI B size finds its roots in the ISO 216 international paper size standard. However, it's important to note that while ISO sizes are based on a consistent aspect ratio of square root of two (√2), ANSI sizes have a more varied aspect ratio. This unique characteristic allows for greater flexibility when scaling documents up or down within the ANSI series.

One fascinating fact about this paper size is its alternate name - 'Tabloid'. The term originated from its extensive use in tabloid newspapers due to its practical dimensions which are ideally suited for compact yet comprehensive newsprint layouts.

In addition to publishing, industries such as architecture, engineering, and design also frequently employ this versatile paper size. Its dimensions provide ample space for detailed drawings or designs without being overly large or unwieldy.

Moreover, with digital technology becoming increasingly prevalent in our lives, the ANSI B has found new relevance. It serves as an optimal choice for scanning large documents into digital formats due to its balanced proportions between width and length.

Whether it's physical print or digital media applications - from newspapers and blueprints to scanned documents - the versatility of ANSI B continues to make it an enduringly popular choice among professionals worldwide.

Interesting facts about ANSI B

1: ANSI B paper is part of the American National Standards Institute (ANSI) paper size series

ANSI B paper is one of the standard sizes in the ANSI series, which was developed by the American National Standards Institute. This series includes various paper sizes commonly used in North America.

2: ANSI B paper dimensions are based on a ratio of 1:√2

The dimensions of ANSI B paper follow a ratio of 1 to the square root of 2 (approximately 1:1.414). This ratio allows for easy scaling and resizing without losing the original aspect ratio.

3: The most common size in the ANSI B series is ANSI B (11 x 17 inches)

The most widely used size in the ANSI B series is known as "ANSI B" or "Tabloid" size, measuring 11 x 17 inches. It is commonly used for brochures, posters, and architectural drawings.

4: ANSI B paper can be folded to create four panels

An interesting feature of ANSI B paper is that it can be folded evenly into four panels. This makes it convenient for creating pamphlets or booklets with multiple pages.

5: The aspect ratio of ANSI B paper matches ISO A3

The aspect ratio (width-to-height ratio) of ANSI B paper matches that of ISO A3, which belongs to a different international standard. This similarity allows for easy conversion and compatibility between these two popular sizing systems.

6: The origins of the ANSI series date back to World War II

The development and standardization of the ANSI series took place during World War II. The need for consistent paper sizes across different industries, such as engineering and manufacturing, led to the creation of this series.

7: ANSI B paper is commonly used in architectural and engineering drawings

Due to its larger size compared to ANSI A, ANSI B paper is often preferred for architectural and engineering drawings. Its dimensions provide ample space for detailed plans and designs.

8: ANSI B paper is compatible with certain printing presses

Some printing presses are specifically designed to handle ANSI B-sized paper. This compatibility makes it easier for businesses and professionals to print large-scale materials without the need for custom resizing.

9: ANSI B paper can be trimmed down to create smaller sizes

If a smaller size is required, ANSI B paper can be easily trimmed down while maintaining its original aspect ratio. This flexibility allows for customization based on specific project needs.

10: The ANSI series has been widely adopted outside of North America

Although initially developed in North America, the ANSI series has gained popularity worldwide. Many countries have adopted these standard sizes due to their practicality and compatibility with other sizing systems like ISO.
