A2 mat sizes

Do you ever look at cards on Pintrest or Splitcoaststampers and wonder what dimensions a person used on their card.  The other day on Pintrest I saw someone had posted mat sizes for an A2 card, I pinned it.  I was looking at the pin today and thought why not take my scraps and create the sizes.  I marked each size.  I have not clipped them together yet but I am going to with a binder ring.

Now I can actually pull out the mat and use it to help when designing a card, hopefully meaning I don't waste as much paper.
