Choosing the correct paper size is crucial for any printing project, whether it’s for professional documents, marketing materials, or architectural drawings. Understanding the different standard paper sizes will ensure your prints are perfectly suited for their intended purpose. This guide will walk you through the most common paper size standards used globally, focusing on both the ISO (International Organization for Standardization) metric system and the North American standards.
The two primary systems you’ll encounter are the ISO standard, widely adopted around the world, and the North American system, prevalent in the United States and Canada. Let’s delve into each of these to clarify the options available for your printing needs.
ISO Standard Paper Sizes: A and B Series
The ISO 216 standard defines the internationally recognized paper sizes, categorized into series such as A and B. The A series is based on a principle of maintaining aspect ratio when halving the paper size. A0 is the largest, and each subsequent size (A1, A2, A3, A4, etc.) is created by halving the longer dimension of the preceding size. A4, a ubiquitous size, is part of this series and is slightly narrower and longer than the North American Letter size.
Here’s a breakdown of the ISO A series dimensions:
- A0: 841 mm x 1,189 mm (33.11 in x 46.81 in) – Commonly used for posters and large format drawings.
- A1: 594 mm x 841 mm (23.39 in x 33.11 in) – Suitable for posters, architectural plans, and flip charts.
- A2: 420 mm x 594 mm (16.54 in x 23.39 in) – Ideal for posters, presentations, and large diagrams.
- A3: 297 mm x 420 mm (11.69 in x 16.54 in) – Often used for brochures, newsletters, and tables.
- A4: 210 mm x 297 mm (8.27 in x 11.69 in) – The standard paper size for general documents, letters, and magazines in most countries outside North America.
- A5: 148 mm x 210 mm (5.83 in x 8.27 in) – Commonly used for notebooks, flyers, and leaflets.
- A6: 105 mm x 148 mm (4.13 in x 5.83 in) – Good for postcards and smaller promotional materials.
- A7: 74 mm x 105 mm (2.91 in x 4.13 in) – Used for small notepads and tickets.
The ISO B series paper sizes provide a slightly larger option compared to the A series for the same number. They are also derived in a similar manner, and here are some key B sizes:
- B0: 1,028 mm x 1,456 mm (40.48 in x 57.32 in)
- B1: 707 mm x 1,000 mm (28.66 in x 40.48 in)
- B2: 514 mm x 728 mm (20.24 in x 28.66 in)
- B3: 364 mm x 514 mm (14.33 in x 20.24 in)
- B4: 257 mm x 364 mm (10.12 in x 14.33 in)
- B5: 182 mm x 257 mm (7.17 in x 10.12 in)
- B6: 128 mm x 182 mm (5.04 in x 7.17 in)

North American Paper Sizes: ANSI and ARCH
In North America, particularly in the USA and Canada, different standard paper sizes are used. The ANSI (American National Standards Institute) sizes are common for general documents, while ARCH (Architectural) sizes are used in architecture, engineering, and construction.
ANSI sizes are designated by letters, starting with ANSI A, which is the equivalent of the common “Letter” size:
- ANSI A (Letter): 8.5 in x 11 in (215.9 mm x 279.4 mm) – The standard for business and academic documents in North America.
- ANSI B (Tabloid/Ledger): 11 in x 17 in (279.4 mm x 431.8 mm) – Used for larger spreadsheets, diagrams, and booklets.
- ANSI C: 17 in x 22 in (432 mm x 559 mm) – Suitable for posters and medium-sized technical drawings.
- ANSI D: 22 in x 34 in (559 mm x 864 mm) – Used for larger technical drawings and posters.
- ANSI E: 34 in x 44 in (864 mm x 1118 mm) – For large posters, banners, and detailed engineering drawings.
ARCH sizes are specifically designed for architectural drawings and offer dimensions in whole inches, making calculations simpler for architects and builders:
- ARCH A: 9 in x 12 in (229 mm x 305 mm)
- ARCH B: 12 in x 18 in (305 mm x 457 mm)
- ARCH C: 18 in x 24 in (457 mm x 610 mm)
- ARCH D: 24 in x 36 in (610 mm x 914 mm)
- ARCH E: 36 in x 48 in (914 mm x 1219 mm)

Quick Comparison: ISO vs. North American
While both systems offer a range of paper sizes suitable for various printing tasks, the ISO system is based on metric measurements and a consistent aspect ratio, making it scalable and logically structured. North American sizes, especially ANSI Letter, are deeply ingrained in business and education settings in the region. It’s important to note that A4 is slightly taller and narrower than Letter size, which can be a consideration when printing documents designed for international audiences or vice versa.
Choosing the Right Paper Size for Your Printing Project
Selecting the appropriate paper size depends heavily on the type of project. For standard documents and letters in most parts of the world, A4 is the norm. In North America, Letter size is the standard. For larger format printing like posters or architectural plans, sizes like A0, A1, ANSI D, or ARCH D become relevant. Consider the final use of your printed material, the region you are in, and the standards expected by your audience or industry.
