Poster frame size definition

All poster frames are defined by the size of the insert.
The overall frame size is therefore slightly larger.
The visible area (sometimes called the 'safe copy area') is less than the paper size for most poster fames. 
Do not print text or logos 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 most countries in the world - the important exceptions being USA and Canada.
In UK a few 'inch' sizes are used alongside metric paper sizes - see below.
Remember is that A8 size is very small (about 2in x 3in) and A0 size is big (nearly 3ft x 4ft). 
Every A size is double the previous size: A3 is twice the size of A4, and so forth. 
(North American visitors may not appreciate that Letter size paper and Legal size paper are not generally available in Europe).
Metric name Size in mm (cm) Size in inches
A0 size 841x1188 mm (84x119) 33-1/8 x 46-3/4 in
A1 size 594x841 mm (60x84) 23-3/8 x 33-1/8 in
A2 size 420x594 mm (42x60) 16-1/2 x 23-3/8 in
A3 size 297x420 mm (30x42) 11-3/4 x 16-1/2 in
A4 size 210x297 mm (21x30) 8-1/4 x 11-3/4 in
A5 size 148x210 mm (15x21) 5-7/8 x 8-1/4 in
A6 size 105x148 mm (10x15) 4-1/8 x 5-7/8 in
A7 size 74x105 mm (7.5x10) 2-7/8 x 4-1/8 in
A8 size 52x74 mm (5x7.5) 2-1/8 x 2-7/8 in
1/3A4 (DL size) 99x210 mm (10x21) 3-7/8 x 8-1/4 in
1/4A4 (Qtr.A4) 74x210 mm (7.5x21) 2-7/8 x 8-1/4 in
To calculate in cm use mm above and move the decimal point one space to the left:
210mm is 21cm.  The above cm sizes are nominal (i.e. rounded to the nearest cm)
