Have you ever been confused by the different numbers and letters on printer paper packaging? Terms like A4, Letter, Legal, and Tabloid can seem like a jumble, leaving you wondering about the actual standard printer paper size and the distinctions between them.
Let’s clarify the world of paper sizes. This guide will demystify these standards and cover the essential information you need to know, including:
- Defining standard paper size systems.
- Exploring traditional North American paper sizes.
- Understanding the origins of these standard sizes.
- Practical advice on printing A4 documents.
- Determining the paper size your printer typically uses.
What is Standard Paper Size?
Currently, two primary paper size systems are prevalent globally: the international ISO 216 standard and the North American system. While the ISO 216 standard enjoys worldwide recognition, the United States and Canada primarily utilize the North American system, which differs in its dimensions.
In the United States, the most commonly used standard printer paper sizes are:
- Letter (8.5 × 11 inches): This is the workhorse size for everyday office documents, general printing, and academic papers.
- Legal (8.5 × 14 inches): As its name suggests, Legal size paper is frequently used for legal documents, contracts, and forms requiring extra vertical space.
- Tabloid (11 × 17 inches): Also known as Ledger, Tabloid size paper is popular for creating newsletters, brochures, larger charts, and smaller newspapers.
Traditional North American Paper Sizes in Detail
The North American system is characterized by specific formats and aspect ratios for its standard printer paper sizes. The table and graphic below provide a clear overview of the most common paper sizes in the United States, showing both imperial and metric measurements.
| Format | Size in Inches | Size in Millimeters |
|---|---|---|
| Letter | 8.5 x 11 | 216 x 279 |
| Legal | 8.5 x 14 | 216 x 356 |
| Tabloid (Ledger) | 11 x 17 | 279 x 432 |

How Were Standard Paper Sizes Determined?
The dimensions of today’s standard printer paper sizes are rooted in a combination of historical practices and practical considerations. The ISO 216 standard, established in 1975, is the basis for the international standard printer paper size A4, which measures 8.27 x 11.69 inches (210 x 297 mm). A4 is the globally recognized size for letterhead and documents in most countries outside of North America.
In contrast, the U.S. standard printer paper size, Letter (8.5 x 11 inches), has a longer history of use in the country. Interestingly, President Herbert Hoover attempted to change this in the early 1930s, advocating for an 8 x 10.5 inch standard for all government paperwork. However, it wasn’t until the Reagan administration in the 1980s that the U.S. government officially adopted the 8.5 x 11 Letter size, aligning with the prevalent standard printer paper size used across most American institutions and businesses.
The standardization was further solidified in 1995 when the American National Standards Institute (ANSI) through ANSI/ASME Y14.1 standard formally recognized and standardized various U.S. paper sizes, including 8.5 x 11 for engineering drawings and general use, confirming Letter as the primary standard printer paper size in the US.
Understanding this historical context clarifies why regular copy paper in the U.S. is not the same as A4 paper. The visual below highlights the slight but significant size difference between the international standard (A4) and the North American standard Letter size.

How to Print A4 Documents Effectively
While the international A4 standard printer paper size is close to the US Letter size, the slight dimensional differences can cause issues when printing documents designed for A4 on Letter-sized paper. For instance, a PDF document formatted for A4, when printed directly on Letter paper, may have content cut off at the top and bottom edges.
Fortunately, resolving this is straightforward. A4 paper is approximately 6% taller than Letter size. To ensure an entire A4 document fits correctly onto Letter-sized paper, adjust your printer settings to reduce the magnification to 94%. Conversely, if you are sending a Letter-sized document to someone in a country that uses A4, advising them to print at 97% magnification is helpful, as A4 is about 3% narrower than Letter size.
What Size Paper Do Printers Typically Use?
In the United States, the default setting for most office printers and copiers is the Letter standard printer paper size (8.5 x 11 inches). These machines are usually equipped with paper trays pre-loaded with Letter-size paper and offer easy options to switch to Legal or Tabloid size paper through control panel selections.
Beyond size, the quality of paper is also crucial for optimal printing. Using good quality copy paper is as important as choosing the correct standard printer paper size. Lower quality, cheap paper can produce excessive lint and increase the likelihood of paper jams, leading to printing frustrations and potential printer damage. Investing in quality paper ensures smoother printing and prolongs the life of your printer.
