A0 size in millimetres with bleed area

Would you like to have your print file printed at a printer? Then one of the delivery specifications is often to use a bleed area of 3 mm (all around) in your print file. This changes the ‘gross’ size, so it is important that you do not forget this.

A bleed area of 3 mm means an extra 6 mm around your A0 paper size. Both in length and width. With an A0 this means that your net size is 841 x 1189 mm. And the gross size (including bleed area) is 844 x 1192 mm. Then the printer cuts away the bleed area, so that the background of your A0 runs neatly to the edge.
