Untrimmed Paper Formats – All A and B series formats described previously are trimmed paper end sizes – i.e. the size when delivered to the end user or client. Other ISO standards define the format series RA and SRA for untrimmed raw paper which is normally the size when received by the printers. These sizes are useful to know when planning up your print projects.

RA Series Formats
RA0 – 860mm x 1220mm
RA1 – 610mm x 860mm
RA2 – 430mm x 610mm
RA3 – 305mm x 430mm
RA4 – 215mm x 305mm

SRA Series Formats
SRA0 – 900mm x 1280mm
SRA1 – 640mm x 900mm
SRA2 – 450mm x 640mm
SRA3 – 320mm x 450mm
SRA4 – 225mm x 320mm
