Paper sizes (formats)

In the office printing business we are so used to the generalization that all paper is letter size, that we often forget that is just one size in which we can buy cut sheet paper. Here is a handy compilation of popular sizes.

A series (main series)

A0 is 1 square meter. Formula: h = w * sqrt (2), i.e., the ratio of the sides is sqrt (2).

This is the normally used series.

A number size (mm) size (inch) area (m^2)
A0 841 x 1189 33.1 x 46.8 1.0
A1 594 x 841 23.4 x 33.1 0.5
A2 420 x 594 16.5 x 23.4 0.25
A3 297 x 420 11.7 x 16.5 0.125
A4 210 x 297 8.3 x 11.7 0.063
A5 148 x 210 5.8 x 8.3 0.031
A6 105 x 148    
A7 74 x 105    
A8 52 x 74    
A9 37 x 52    
A10 26 x 37    

B series (auxiliary series)

B0 is 1 m long on the short side.

This series is sold only in cut sheets (in plano) and can be used only if the required size is not available in the A series.

C series (intermediary series)

Geometric average between series A and series B. Example: C4 = sqrt (A4 * B4).

This series has been designed especially for envelopes and other mailing containers.

Old European Formats

These formats were in use before the normalization and can still be found today in the graphic arts. This is just a selection in plano (= unfolded) papers. When the papers are folded, the name is prefixed by the folding number (e.g., in 4º Jésus refers to the Jésus format folded in four); usually the Latin names are used:

  • in folio, 2 sheets or 4 pages
  • in quarto, 4 sheets or 8 pages
  • in octavo, 8 sheets or 16 pages
  • in 16, etc.
