Paper or Craft Card sizing can be confusing but once you know what to look for you'll have no trouble choosing the right size for your projects. The 'A' system is fairly straightforward and so long as your remember 'the smaller the number the bigger the paper' then you can't go far wrong.
Here is a look at the most common sizes:
The sizes start at A0 and then get smaller as if you've folded the paper in half.
Card Blank sizes
When it comes to card blanks, the size given is it's folded size - i.e. the face or front of the card.
For example: An A6 card blank is card with the size of the front being A6 (10.5cm x 14.8 cm) but the card is made from a piece of A5 card.
Other sizes include square cards whose sizes come in cm or inches like our 3' x 3' square cards.
If you are wanting to put your cards into envelopes then these so the 'C' system which relates to the A system above but are slightly bigger to allow room for the card to fit into the envelope.
For example: An envelope for an A4 card would be sized as C4.
Square envelopes are size to give the card room as above. This also goes for cello bags too which are sized to allow room to fit your card inside.
