RA2

The RA2 paper size is one of the middle sizes in the ISO 217 series of raw, untrimmed paper formats. It has dimensions of 430 mm x 610 mm, giving it a surface area of approximately 0.262 square meters. The RA designation indicates this is a 'raw format A' size, oversized from the A series to allow bleed printing. RA2 is slightly larger than the more widely used A2 size which is 420 mm x 594 mm. RA2 sees frequent use for oversized printing jobs needing bleed allowance. Typical applications include posters, large brochures, greeting cards, fold-out pamphlets, and educational materials. After printing, RA2 sheets are often trimmed down to A2 size for binding or display. The convenient 1:√2 aspect ratio of RA2 enables efficiently printing 2 pages on a single sheet. Like other raw formats, RA2 was established in 1975 by the ISO 217 standard on untrimmed paper sizes. In summary, at 430 x 610 mm, RA2 serves as a versatile raw sheet for printing projects requiring an oversized format for bleed purposes.
