DIN formats and poster formats in advertising

Frequently asked questions that we receive by e-mail or telephone deal with DIN formats and poster formats in general as well as with the visible areas of DIN formats when used in aluminium snap frames or customer stoppers and light boxes with snap frames in particular. For general understanding, here is an overview of the common DIN formats:

We all know them - more or less - the DIN formats!

While it was enough to tell the A5-A3 formats apart when we were schoolchildren, much larger DIN formats come into play in outdoor advertising and at the POS. The DIN formats we use start at A0 (842 x 1189mm = 1sqm) and end at A7 (74 x 105mm= ID card size). The DIN series relevant for us are the DIN A formats. For special areas there are also the DIN B to D series - DIN B is used for the untrimmed DIN A format, which is used in print shops, and the DIN C format, which is sometimes used for envelopes and mailing envelopes.

The ratio of width to height for all formats is approx. 5:7 (i.e. 1:1.414) or the ratio 1: √2. It is only through this ratio that it is possible to halve a DIN A0 sheet again and again to the next smaller format. So much for the theory, now for the practice:

The right frame for your posters - poster size & visual format

When choosing a poster framefor your posters, you need to consider the following: The folding profiles of the frames cover approx. 10 mm of the poster all around, depending on the profile width.
You must therefore subtract the circumferentially covered edge area from the poster format (= DIN format = insert format) to obtain the visible format. When designing poster motifs, logos, lettering, etc. should therefore not be placed directly in the border areas.
However, you should always design backgrounds etc. over the entire surface and let them flow out so that no flash edges form between the visual format and the frame.

So always mentally subtract approx. 10mm all around in order to optimally design your posters. Of course, these specifications also apply to the poster formats 500 x 700mm (also called B2) and 700 x 1,000mm (also called B1), which are also widely used but are not DIN dimensions.

This also applies to a wide variety of poster frames and snap frames, as well as to advertising displays (customer stoppers, poster stands) and light boxes. Of course, there are production-dependent differences here - it is best to clarify this point when placing the order.
