International Paper Sizes

When it comes to paper sizes, the ISO 216 standard is the most widely used international standard. This standard defines the A series paper sizes, which are commonly used in most countries across the world. The A series paper sizes are based on a simple principle: each size is half the size of the previous size, starting from A0, which has an area of one square meter.

Explanation of the ISO 216 standard for paper sizes

The ISO 216 standard was established in 1975 and is widely recognized for its practicality and ease of use. The standard defines the A series paper sizes, which are commonly used for printing, stationery, and other applications. The A series paper sizes are based on the aspect ratio of the square root of 2 and are designed to provide a consistent and proportional size for all paper sizes.

Dimensions and uses of the A series paper sizes

The A series paper sizes range from A0 to A10, with A0 being the largest and A10 being the smallest. The dimensions of the A series paper sizes are as follows:

  • A0: 841 x 1189 mm
  • A1: 594 x 841 mm
  • A2: 420 x 594 mm
  • A3: 297 x 420 mm
  • A4: 210 x 297 mm
  • A5: 148 x 210 mm
  • A6: 105 x 148 mm
  • A7: 74 x 105 mm
  • A8: 52 x 74 mm
  • A9: 37 x 52 mm
  • A10: 26 x 37 mm

The A4 size is the most commonly used paper size in the A series, and it is the standard size for most printers, copiers, and fax machines. The A5 size is often used for brochures, flyers, and invitations, while the A3 size is commonly used for posters and presentations.

The A series paper sizes are widely used for both personal and professional applications, and they provide a consistent and standardized size for printing and other uses.
