Untrimmed paper formats

All A and B series formats described so far are trimmed paper end sizes, i.e. these are the dimensions of the paper delivered to the user or reader. Other ISO standards define the format series RA and SRA for untrimmed raw paper, where SRA stands for "supplementary raw format A" ("sekundäres Rohformat A"). These formats are only slightly larger than the corresponding A series formats. Sheets in these formats will be cut to the end format after binding. The ISO RA0 format has an area of 1.05 m² and the ISO SRA0 format has an area of 1.15 m². These formats also follow the sqrt(2)-ratio and half-area rule, but the dimensions of the start format have been rounded to the full centimeter. The common untrimmed paper formats that printers order from the paper manufacturers are

RA Series Formats SRA Series Formats
RA0 860 × 1220 SRA0 900 × 1280
RA1 610 × 860 SRA1 640 × 900
RA2 430 × 610 SRA2 450 × 640
RA3 305 × 430 SRA3 320 × 450
RA4 215 × 305 SRA4 225 × 320

The RA and SRA dimensions are also used as roll widths in rotating printing presses.
