Have you ever found yourself staring at a dropdown list of paper sizes on your printer settings, wondering why there are so many options? It's like trying to pick the right fork at a fancy dinner—confusing and overwhelming. The confusion can double if you're an office worker dealing with international clients. You want to ensure your documents print correctly on the other side of the pond, but the varying paper sizes can make it challenging.
Why are there so many paper sizes? What do they all mean, and when is it best to use each? These questions are all too common in the printer world. As print vendors for nearly 40 years, we know the ins and outs of printing and paper.
Today, we’re here to help you navigate the world of printer paper sizes. By the end of this blog, you'll understand the different paper sizes, their uses, and how to choose the right one for your needs.
Standard Paper Sizes in the U.S.
The most commonly used paper sizes in office settings in the U.S. and North America are Letter, Legal, and Tabloid. Here's a quick rundown of the most popular sizes:
Letter (8.5 x 11 inches)
If you've ever printed a document at home or in the office, you've most likely used Letter-sized paper. This size is 8.5 x 11 inches and is the default on most printers/copiers. It originated from the North American paper industry standard in the early 20th century and fits perfectly in most printers and copiers, making it a go-to choice for standard documents.
- Use Cases: Ideal for everyday printing tasks like reports, letters, and resumes. It is also great for pamphlets and folded brochures.
Legal (8.5 x 14 inches)
Another standard paper size is legal-sized paper, measuring 8.5 x 14 inches. Depending on your printer type, you’ll likely need a separate paper tray when printing with this paper. Developed to accommodate longer documents, its extra length allows for more detailed information on a single page. This size is typical in law offices and other settings where lengthy documents are frequently printed.
- Use Cases: Commonly used for legal documents, hence the name, and contracts.
Tabloid (11 x 17 inches)
Tabloid-sized paper, also known as Ledger, is 11 x 17 inches. When printing on a multifunction printer (MFP), you'll need an additional tray setup. Originating from the publishing and advertising industries, its larger area is perfect for graphics and text, making it useful for marketing materials and design layouts.
- Use Cases: Perfect for presentations, posters, and small print newspapers.
These sizes are standard in North America because they fit the majority of printers and office needs. This ensures you can share documents easily and print them across various platforms.
Why Different Countries Use Different Paper Sizes
You might wonder why the U.S. uses different paper sizes compared to other countries like the U.K. and Australia. The answer lies in historical development and how processes have become more standardized.
The American Standard (ANSI)
The U.S. follows the ANSI (American National Standards Institute) standards for paper sizes, which evolved independently of other international standards. The sizes were determined based on the needs of American businesses and the printing technology available at the time. Letter format, also known as ANSI A size, is the most common size in this system.
This system uses imperial measurements (inches), which is why U.S. paper size dimensions are often expressed in inches.
The International Standard (ISO)
Most of the world uses the ISO (International Organization for Standardization) 216 standard, which was established in 1975. This system is based on the A-series paper sizes derived from a mathematical ratio, making resizing and scaling more efficient. Also known as the A-class, these papers range from size A0 to A10, with A10 being the smallest size. This means that the most common A-class size, A4, is half the size of paper size A3.
Additionally, ISO standards include B-series paper sizes, such as B4, B5, and B6, which are used for posters, books, and envelopes, offering more flexibility in design and printing.
The sizes in the ISO system use metric measurements (millimeters), which makes them more consistent and scalable globally.
What Are the Implications of this Difference?
While the ISO and ANSI standards are very similar, there are a couple of things to keep in mind when alternating between both standards:
- Printing Compatibility: Documents created on Letter-sized paper may not fit perfectly when printed on A4 paper, leading to formatting issues.
- Business Communication: You must know the differences between these standards, especially if you do international business. This way, you ensure your documents are professional and correctly formatted for recipients abroad.
Standard ISO Sizes
As we stated earlier, the A-class paper sizes dominate in many parts of the world. Here's a look at the most common ones:
A4 (210 x 297 mm)
If you've ever received a document from Europe, it was likely on A4 paper. This is the most common A-class paper size. With dimensions of 210 x 297 mm (or 8.3 x 11.7 in), A4 is the standard size for everyday office printing. A4 paper size is designed for efficiency and scalability and fits most European inkjet and laser printers. It’s the ISO equivalent of the Letter size in the U.S.
- Use Cases: Widely used for letters, forms, and standard office documents.
A3 (297 x 420 mm)
A3 paper is 297 x 420 mm (or 11.7 x 16.5 in) and is similar in size to tabloid-sized paper. As part of the ISO series, A3 offers a larger print area, making it great for detailed documents and graphics.
- Use Cases: Ideal for large charts, posters, and presentations.
A5 (148 x 210 mm)
A5 paper, measuring 148 x 210 mm (5.8 x 8.3 in), is half the size of A4. It’s commonly used for smaller print materials. Its compact size is convenient for portable documents and handouts.
- Use Cases: Common for booklets, flyers, and diaries.
Here’s a visual comparison of the most common sizes in the ANSI and ISO standards.
Non-Standard Paper Sizes and Their Uses
Beyond the standard sizes common in offices, there are several less common or non-standard paper sizes used for specific purposes:
Half-Letter
This paper size measures 5.5 x 8.5 inches and is used for smaller booklets, brochures, and planners. Its compact size is perfect for portable documents and notes.
Executive
Sometimes, you'll come across Executive-sized paper, which is 7.25 x 10.5 inches. Often used for personal stationery and smaller reports, this size provides a unique, professional look for certain documents.
Government Letter
You might recognize Government Letter-sized paper if you've dealt with government forms. At 8 x 10.5 inches, it’s typically used for government forms and official documents. This size, slightly smaller than the standard Letter size, is often mandated by government standards.
Digital Sizes
When printing large photos or high-quality prints, you've probably used 13 x 19 inches paper, also known as Super B. This size is commonly used in digital printing for posters, art prints, and proofs due to its ability to accommodate detailed, high-resolution images and graphics. Other digital sizes include 12 x 18 inches and 14 x 20 inches.
Movie Posters
To grab your attention, movie posters come in large sizes. Typically 24 x 36 inches, these posters are used for promotional purposes. Their large format is perfect for high-impact visuals and advertising.
Billboards
If you’ve ever driven down a highway, you’ve most likely seen a billboard. These come in various sizes, typically starting at 48 x 14 feet, and are used for outdoor advertising.
Their massive size ensures visibility from a distance, which is ideal for advertising to large audiences.
For larger paper sizes like movie posters and billboards, a production printer is ideal. Production printers are designed to handle various paper sizes, types, and finishes, making them efficient for commercial needs.

How to Choose the Right Size of Paper When Printing
Choosing the right paper size depends on several factors:
Document Purpose
- Standard Documents: Use Letter (U.S.) or A4 (Europe).
- Legal Documents: Opt for Legal size.
- Large Graphics: Choose Tabloid or A3.
Printer Specifications
- Paper Handling Capacity: Check your printer’s manual to see what sizes it supports. Most printers can handle Letter and Legal, but Tabloid and A3 may require special capabilities.
- Paper Trays: Ensure you have the correct paper tray or feeder for larger sizes.
- Print Finishers: Understanding your paper sizes is also important when using print finishers such as staplers, folders, and binders. These tools often have specific size requirements to function correctly and provide professional finishing touches to your documents.
Why Is Understanding Paper Sizes Important?
Understanding printer paper sizes is crucial for anyone who values the professional presentation of their documents and images. Knowing the correct size ensures your documents look how they’re intended to and are easy to print, no matter where they're sent.
A common issue arises when you don’t have the correct paper size that matches the size of the document you want to print. For example, if your digital document is in tabloid size, but your printer is set to letter size, you won’t be able to print it out. So, make sure you double-check, and adjust your digital document size accordingly before you print.
High-Quality Prints
Using the wrong size can lead to issues like misaligned text, cut-off graphics, and poor overall presentation. Proper paper sizing ensures that your printed materials look sharp, clean, and professional.
Additionally, understanding the types of paper is equally important, as they can affect the quality of your prints. For more information, check out our blog on printing paper types.
