At Banner World we print posters to any custom size onto a wide range of materials suitable for indoor or outdoor use. Several materials are also specifically designed for use in lightboxes. Click here to see our range of poster printing materials.

In the United Kingdom we use 2 different poster size specifications, ISO 216 A series and UK Billboard.

A Series is the most commonly used poster size specification in the UK, with many poster frames and pavement signs being designed to accommodate sizes such as A4, A3, A2, A1 and A0.

  • A4 – 210 x 297mm
  • A3 – 297 x 420mm
  • A2 – 420 x 594mm
  • A1 – 594 x 841mm
  • A0 – 841 x 1189mm
  • 2A0 – 1189 x 1682mm

UK Billboard Poster Sizes

Billboards, or advertising hoardings, are found on roadsides, bus shelters, train stations and on buildings to attract the attention of passing foot and vehicle traffic. Planning permission is usually required for larger new installations.

Posters in Frames

Posters to be fitted into frames may need to be trimmed slightly smaller and will have a ‘safe area’ for the poster design to take account of the frame profile. Always check this before placing your order or designing your artwork!
