US Letter

  • Dimensions: 8.5 inches (width) x 11 inches (height) or approximately 216 mm x 279 mm.

A4

  • Dimensions: 8.27 inches (width) x 11.7 inches (height) or approximately 210 mm x 297 mm.

A4 is the international standard paper size used in most countries outside of North America. It is widely used for documents such as letters, resumes, and business reports due to its balance between readability and compactness.

A3

  • Dimensions: 11.7 inches (width) x 16.5 inches (height) or approximately 297 mm x 420 mm.

This format is part of the international standard paper size series known as ISO 216. It is twice the size of A4 and is commonly used for posters, presentations, and large-format printing.

A5

A5 is half the size of A4 and is usually used for smaller booklets, brochures, and notepads. It offers a more compact format while still maintaining readability for text and images.
