The A5 is part of a set or range of page sizes, called the ISO A or ISO 216 standard. This international standard is based on the German DIN 476 standard of 1922. In reality, A5 is often referred to as DIN A5. The Japanese have adopted the same range of paper sizes in their JIS P 0138-61 standard.

By folding an A5 in two on the shorter side, an A6 document is created. Two A5 pages side by side on a sheet equals A4 paper size. This creates a range of paper sizes from A0 (which has a surface area of one square meter) to A10. The height/width ratio is kept constant (1:1.41 or the square root of 2) for all sizes. Dimensions are always rounded to the nearest millimeter.

A5 size in pixels

To print an image correctly, it must have a minimum resolution. The number of pixels depends on the required output quality.

  • At 300 dpi (pixels per inch) the image must be 1748 x 2480 pixels. This is the resolution required for quality offset printing that will be viewed at close range (such as books, brochures, magazines, calendars,…). For photo books, this is also the optimal resolution, but a somewhat lower pixel count (250 dpi) is acceptable for high-quality photographs.
  • At 150 dpi, the image should be 874 x 1240 pixels. This is the minimum resolution for newspapers or posters viewed from a fairly close distance.

A digital camera with decent image quality and a resolution of 4 megapixels or more can be used to print high quality A5-size photographs.

We leave you a table about the different pixel sizes of A5 size. The pixel measurements to use will depend on the type of work you are going to do, whether it is for printing a poster, a billboard or if it is simply an image for a web page.

Which size is larger DIN A5 or A6 size

The A5 is larger than the A6. By folding an A5 size sheet in half we get two sheets in DIN A6 format.

To give you a rough idea of the different sheet sizes, remember that A0 is the largest size format, then A1, followed by A2 and so on.

The double and half rule is also very useful, for example, one A3 sheet equals two A4 sheets or one size A4 sheet equals two A5 sheets.

When designing or printing a product in A5 size, it is very important to know precisely the exact measurements, to avoid surprises with the final result.
