Most Commonly Used Card Sizes

Need a guide for card sizes?  Me too.  Most of the cards I make are A2.  But, I have a stash of envelopes that are for various card sizes.  So, here's a chart that I created with the measurements for the most commonly used card sizes.

A1	3 ½ × 4 ⅞ 3.5” × 4.875”
A2	4 ¼ × 5 ½ 4.25” × 5.5”
A6	4 ½ × 6 ¼ 4.5” × 6.25”
A7	5” × 7”
Biz	3 ½ × 2 3.5” × 2
Square	5 ½ × 5 ½ 5.5” × 5.5”

 

 

 

 

ETA:  I figured it would be nice to have measurements for the corresponding layers.  Here you go:
