Hi Hans, As discussed at EuroTeX %D here are some extra paper sizes %D ISO RA (raw A) sizes: \definepapersize [RA0] [\c!width=860mm,\c!height=1220mm] \definepapersize [RA1] [\c!width=610mm,\c!height=860mm] \definepapersize [RA2] [\c!width=430mm,\c!height=610mm] \definepapersize [RA3] [\c!width=305mm,\c!height=430mm] \definepapersize [RA4] [\c!width=215mm,\c!height=305mm] %D ISO SRA (supplementary raw A) sizes: \definepapersize [SRA0] [\c!width=900mm,\c!height=1280mm] \definepapersize [SRA1] [\c!width=640mm,\c!height=900mm] \definepapersize [SRA2] [\c!width=450mm,\c!height=640mm] \definepapersize [SRA3] [\c!width=320mm,\c!height=450mm] \definepapersize [SRA4] [\c!width=225mm,\c!height=320mm] %D Industry invention \definepapersize [A3plus] [\c!width=329mm,\c!height=483mm] %D for orthogonality \definepapersize [undersized] [\c!width=\dimexpr(\paperwidth-1.5cm), \c!height=\dimexpr(\paperheight-1.5cm)]
