KNOW YOUR PAPER SIZES

Do you know the paper size difference between a compliment slip and a business card?

Well if you don’t, that’s alright. Just take a look at the range of sizes needed for every document in the following table:

 

Size Name

Size in cm

(without bleed area)

Size in pixels 300dpi

(without bleed area)

Size in cm

(with bleed area)

Size in pixels 300dpi

(with bleed area)

Business Card 8.5 x 5.5 cm 1004 x 650 9.1 x 6.1 cm 1075 x 720
DL / Comp Slip 9.9 x 21.0 cm 1169 x 2480 10.5 x 21.6 cm 1240 x 2551
A6 14.8 x 10.5 cm 1748 x 1240 15.4 x 11.1 cm 1819 x 1311
A5 21.0 x 14.8 cm 2480 x 1748 21.6 x 15.4 cm 2551 x 1819
A4 29.7 x 21.0 cm 3508 x 2480 30.3 x 21.6 cm 3579 x 2551
A3 42.0 x 29.7 cm 4961 x 3605 42.6 x 30.3 cm 5031 x 3579
A2 59.4 x 42.0 cm 7016 x 4961 60.0 x 42.6 cm 7087 x 5031
A1 84.1 x 59.4 cm 9933 x 7016 84.7 x 60.0 cm 10004 x 7087
A0 118.9 x 84.1 cm 14043 x 9933 119.5 x 84.7 cm 14114 x 10004

 

The International Organisation for Standardisation (ISO) 216 standard defines the dimensions of A sized and B sized papers, including the most popular sizes A3, A4 and A5. This is the international paper size standard, but it isn’t used by every country.

 

 

From the illustration above, we can see that the A series of paper has the size aspect ratio 1:√2. With this ratio, when the paper is cut or folded in half width ways, each half still has the same aspect ratio. In other words, A1 is half the surface area of A0, A2 is half the surface area of A1 – and so on.

In printing, we use an oversized paper called Supplementary Raw Format A (SRA) (ISO 217) paper sizes. These paper sizes are 115% of their A series counterparts. The reason we use this untrimmed paper is to allow for bleed, crop marks and binding options. The same ratio used for the A series also applies to the SRA paper sizes.

Have fun designing and printing!
