When people ask what size is normal printer paper, they are usually asking about the paper used in home printers, office printers, school assignments, forms, letters, and everyday documents. In the United States and Canada, the standard printer paper size is Letter size, which measures 8.5 × 11 inches.
This size is widely used for printing documents, reports, resumes, invoices, worksheets, business letters, and general paperwork. However, printer paper size can vary by country. While Letter size is standard in North America, many other countries commonly use A4 paper instead.

What Is Letter Size Paper?
Letter size paper is a standard North American paper size used for everyday printing. Its dimensions are 8.5 inches wide and 11 inches tall. It is commonly used in portrait orientation, although it can also be printed horizontally in landscape orientation.
Letter size is popular because it works well for readable documents, school pages, office forms, contracts, flyers, resumes, and general text layouts. Most printers, scanners, copiers, folders, binders, and filing cabinets in the United States are designed to support Letter size paper.
Letter Size Paper Dimensions
| Unit | Letter Paper Size |
|---|---|
| Inches | 8.5 × 11 inches |
| Millimeters | 216 × 279 mm |
| Centimeters | 21.6 × 27.9 cm |
| Points | 612 × 792 pt |
Why Is 8.5 × 11 Paper Called Letter Size?
The name “Letter” comes from its traditional use for written letters and business correspondence. Over time, it became the default paper size for many official documents in North America.
Today, Letter size is used for much more than letters. It is the default page size in many U.S. office environments, schools, government forms, PDFs, and printing workflows.
What Is Regular Printer Paper Size?
Regular printer paper size depends on the country. In the United States, regular printer paper usually means Letter size. In many other countries, regular printer paper usually means A4 size.
| Region | Common Printer Paper Size | Dimensions |
|---|---|---|
| United States | Letter | 8.5 × 11 in |
| Canada | Letter | 8.5 × 11 in |
| United Kingdom | A4 | 210 × 297 mm |
| Europe | A4 | 210 × 297 mm |
| Australia | A4 | 210 × 297 mm |
| Most of Asia | A4 | 210 × 297 mm |
This is why international documents sometimes print incorrectly if the wrong paper size is selected in the printer settings.
Letter Size vs A4 Paper
Letter and A4 are the two most common paper sizes used for everyday printing, but they are not the same. Letter paper is slightly wider and shorter than A4 paper.
| Paper Size | Inches | Millimeters | Common Use |
|---|---|---|---|
| Letter | 8.5 × 11 in | 216 × 279 mm | United States and Canada |
| A4 | 8.27 × 11.69 in | 210 × 297 mm | Most other countries |
The difference may seem small, but it can affect margins, page breaks, forms, certificates, labels, and print layouts.
Which Is Bigger: Letter or A4?
A4 paper is taller than Letter paper, while Letter paper is slightly wider than A4. This means a document designed for A4 may not fit perfectly on Letter paper without scaling, and a Letter document may need adjustment before printing on A4.
Letter Size vs Legal Size Paper
Legal paper is another common paper size used in offices, especially for contracts, legal documents, agreements, and official paperwork. It has the same width as Letter paper but is longer.
| Paper Size | Dimensions in Inches | Best For |
|---|---|---|
| Letter | 8.5 × 11 in | Everyday documents |
| Legal | 8.5 × 14 in | Contracts and legal forms |
Because Legal paper is three inches longer than Letter paper, it is useful when more vertical space is needed on one page.
Common Printer Paper Sizes
Although Letter is the normal printer paper size in the U.S., printers can often support several other sizes.
| Paper Size | Dimensions | Common Use |
|---|---|---|
| Letter | 8.5 × 11 in | General printing |
| Legal | 8.5 × 14 in | Legal documents |
| Tabloid | 11 × 17 in | Posters, newsletters, diagrams |
| A4 | 210 × 297 mm | International documents |
| A5 | 148 × 210 mm | Booklets, flyers, notebooks |
If you work with multiple paper formats, the Paper Size Converter can help you compare dimensions before printing, designing, or exporting files.
Letter Paper Size in Pixels
When designing documents for digital printing or graphic design, paper size is often measured in pixels instead of inches or millimeters. The exact pixel dimensions depend on the print resolution, commonly measured in DPI (dots per inch).
| Print Resolution | Letter Size Pixels |
|---|---|
| 72 DPI | 612 × 792 px |
| 96 DPI | 816 × 1056 px |
| 150 DPI | 1275 × 1650 px |
| 300 DPI | 2550 × 3300 px |
| 600 DPI | 5100 × 6600 px |
For professional printing, 300 DPI is generally recommended because it produces sharp text and high-quality images suitable for brochures, flyers, reports, and marketing materials.
Where Is Letter Size Paper Used?
Letter size paper is the standard paper format for millions of homes, schools, businesses, and government organizations across North America. Its versatility makes it suitable for almost every type of everyday document.
Home Printing
Most home inkjet and laser printers are configured to print on Letter size paper by default. It is commonly used for recipes, homework, personal documents, and printable forms.
Office Documents
Businesses use Letter paper for contracts, invoices, reports, proposals, employee records, and correspondence because it fits standard filing systems and office equipment.
School Assignments
Students frequently print essays, worksheets, research papers, presentations, and project reports on Letter size paper.
Government Forms
Many official forms, permits, tax documents, and applications in the United States are designed specifically for Letter paper.
How to Choose the Correct Paper Size When Printing
Selecting the correct paper size before printing helps prevent cropped pages, incorrect margins, blank pages, and scaling problems.
Check Printer Settings
Before printing, verify that your printer settings match the paper loaded in the paper tray. If your printer is set to A4 while Letter paper is loaded, the output may not align correctly.
Match the Document Size
Many word processors and PDF files are created using a specific paper size. Make sure the document size matches your printer settings to avoid automatic resizing.
Avoid Automatic Scaling
If possible, print at 100% scale when the document and paper sizes match. Automatic scaling may shrink text, shift margins, or change page layouts.
Letter Size vs Other Common Paper Sizes
Different paper sizes are designed for different purposes. Understanding their dimensions helps you choose the right format for your project.
| Paper Size | Dimensions | Typical Use |
|---|---|---|
| Letter | 8.5 × 11 in | General office printing |
| Legal | 8.5 × 14 in | Legal documents |
| A4 | 210 × 297 mm | International documents |
| A3 | 297 × 420 mm | Large diagrams and posters |
| Tabloid | 11 × 17 in | Newsletters and presentations |
Common Printer Paper Weights
Paper size and paper weight are different specifications. While Letter describes the dimensions, paper weight describes its thickness and durability.
| Paper Weight | Typical Use |
|---|---|
| 20 lb (75–80 gsm) | Everyday office printing |
| 24 lb (90 gsm) | Professional reports |
| 28 lb (105 gsm) | Presentations |
| 65–110 lb Cardstock | Business cards, invitations, brochures |
Choosing the correct paper weight improves print quality and gives documents a more professional appearance.
Common Mistakes When Printing
Many printing problems occur because the wrong paper size or settings are selected. These issues are usually easy to avoid.
Using Letter Instead of A4
International documents designed for A4 may be cropped or scaled when printed on Letter paper.
Incorrect Margins
If margins are too narrow, important content may be cut off because most printers cannot print to the very edge of the page.
Wrong Orientation
Choose portrait for most documents and landscape for spreadsheets, wide tables, or presentations.
Ignoring Print Preview
Always check Print Preview before printing. It allows you to identify layout issues before wasting paper and ink.
