Dimensions of International standard "A" Format Lenticular Poster Prints Sizes

The length of the A set paper dimensions, as based on ISO 216, are shown on the table below both in millimeters and inches. The A Set paper size chart on the right provides a visual explanation of methods the dimensions relates to each other - for instance A5 is 1 / 2 of A4 size paper and A2 is 1 / 2 of A1 size paper.

4A0 & 2A0 - The DIN 476 Oversize or large format Lenticular posters

The sizes bigger than A0, 4A0 & 2A0, aren't formally defined by ISO 216 but are commonly used for oversized or large format posters. The origin of these formats is in the German DIN 476 standard, that was the original base document from which ISO 216 was derived.


A Series Print Size Tolerances

ISO 216 specifies tolerances for the production of A series paper sizes as follows:

  • 1.5 mm (0.06 in) for dimensions up to 150 mm (5.9 in)
  • 2 mm (0.08 in) for lengths in the range 150 to 600 mm (5.9 to 23.6 in)
  • 3 mm (0.12 in) for any dimension above 600 mm (23.6 in)

A Series Paper Sizes Defined

The A series paper sizes are defined in ISO 216 by the following requirements:

  • The length divided by the width is 1.4142
  • The A0 size has an area of 1 square metre.
  • Each subsequent size A(n) is defined as A(n-1) cut in half parallel to its shorter sides.
  • The standard length and width of each size is rounded to the nearest millimeter.

Note: For reference, the last item is there because the root 2 aspect ratio doesn't always give a whole number.
