Definition (keystage 2)
A series of standard sizes for untrimmed paper. They are slightly larger than the corresponding A-series sizes. Printers buy untrimmed paper, bind it and then trim it down to standard A- sizes.
The ratio of side lengths is the same as for A- series, i.e. 1 : √2 , and RA0 size has area 1.05m2, RA1 half this, etc. So the sizes are:
RA0= 860 × 1220 mm;
RA1= 610 × 860 mm;
RA2= 430 × 610 mm;
RA3= 305 × 430 mm;
RA4= 215 × 305 mm.
