What Is Printer Paper Size

Non-Standard Printer Paper Sizes

While standard paper sizes are the most commonly used, there are also non-standard paper sizes available. These sizes are used for specific purposes, and some are even designed for use with specific printers or machines.

One example of a non-standard paper size is the A7 size, which measures 74 x 105 mm. This paper size is commonly used for creating small cards or invitations. Another example is the B5 size, which measures 176 x 250 mm. This size is used in countries such as Japan and is slightly larger than the standard A5 size.

There are also other non-standard sizes such as tabloid or ledger paper, which measures 11 x 17 inches. This size is commonly used for printing larger documents such as posters or brochures.

Choosing the Right Printer Paper Size

When choosing the right printer paper size, there are several factors to consider. The first factor is the type of project you are working on. For example, if you are printing a document for a professional presentation, you may want to use a standard size such as A4 or letter size paper.

Another factor to consider is the printer you are using. Some printers are designed to handle specific paper sizes, so it’s important to check the printer’s specifications before choosing a paper size.

The final factor to consider is the cost. Non-standard paper sizes may be more expensive than standard sizes, so it’s important to weigh the benefits of using a specific size against the cost.

To select the appropriate paper size for your project, consider the following tips:

  1. Determine the purpose of your project and the type of document you will be printing.
  2. Check the printer’s specifications to see which paper sizes it can handle.
  3. Consider the cost of the paper size and weigh the benefits against the cost.
  4. Choose a paper size that best fits your project’s needs and specifications.

Printer Paper Size Standards by Country

In addition to standard and non-standard paper sizes, different countries also have their own paper size standards. The most commonly used paper size standard is the ISO paper size standard, which is used by most countries worldwide, except for the United States and Canada.

The ISO paper size standard was established in 1975 and is based on the German DIN 476 standard. The standard defines the A series and B series of paper sizes, which are used for printing and other business purposes. The A series sizes range from A0 to A10, with A0 being the largest size and A10 being the smallest. The B series sizes range from B0 to B10 and are also used for printing and other business purposes.

Other countries have their own paper size standards that are often based on the ISO paper size standard. For example, in Japan, the JIS paper size standard is used, which is based on the ISO paper size standard. The JIS paper size standard defines the B series sizes, but with slightly different dimensions than the ISO B series sizes.


In conclusion, printer paper size is an important consideration for anyone who uses a printer. Standard paper sizes such as A4 and letter size are the most commonly used sizes, but there are also non-standard sizes available for specific purposes. When choosing the appropriate paper size, it is important to consider the type of document being printed, the printer being used, and any specific requirements for the project.

It is also important to be aware of the different paper size standards used in different countries, such as the ISO paper size standard and the JIS paper size standard. By understanding the different paper size options available, individuals and businesses can make informed decisions when choosing the appropriate paper size for their needs.
