Poster frame size definition
All poster frames are defined by the paper insert size.
The external frame size is always slightly larger.
The visible area is slightly less than the paper size for most poster fames. Do not print critical content too near the edge of the page!
Metric Paper Sizes
Metric paper sizes are also known as SI (Systeme Internationale) or DIN (German Standard) paper sizes.
They are used in 95% of the countries in the world - the important exceptions being USA and Canada.
In United Kingdom a few 'inch' sizes are used alongside metric sizes - see below.
Remember that A8 is very small (about 2in x 3in) and A0 is big (nearly 3ft x 4ft).
Every A size is double the previous size: A3 is twice the size of A4, and so forth.
(See our Top Tips article for more detailed information about paper sizes and why they are important: especially relevant to North American visitors).

B series paper sizes
We can offer B0, B1 and B2 size poster frames to special order. These B sizes are popular in Continental Europe but in the UK they are not generally stock sizes. There is some variance between European, American and Japanese B1 size. Unless specified otherwise we produce B size frames to suit the following poter sizes:
B2 size 500 x 700mm (50x70 cm)
B1 size 700 x 1000mm (70x100 cm)
B0 size 1000 x 1400mm (100x1400 cm)
