Envelopes for your DIY Greeting Cards

Updated for 2019 Rates

As a DIY cardmaker & rubberstamper for 20 years, I do something that many don’t worry about – I base the size of my greeting card on the size of the envelope!

The reason why is because the US Post Office (USPS) has standard envelope sizes for postage – and I dislike paying more for first-class postage ($.55) than I have to.  *Ü*

Here are some envelope factors that will require you to pay more in postage ($0.15 per additional ounce and $.70 for odd-size as of this post):

  • envelopes that are not rectangle in size (tip:  always make sure you address your envelopes horizontally, not vertically, to be considered standard rectangle shape)

  • envelopes that are square cost more – as I mentioned above, any envelope that is not rectangle is size costs more – so a square envelope will cost you $.15 more.  Most wedding invitations are not only square, they are also  usually more than one ounce.  EXAMPLE:  a Square envelopes that is 2 ounces would cost you $.85 to mail ( $.70 + $.15)

  • envelopes that are more than 1/4″ thick (tip:  be careful with your ribbon & embellishments when making your greeting cards)

  • envelopes that don’t bend easily (tip:  avoid more than 4 layers of cardstock (!) when creating your masterpiece)

  • envelopes that have claps, strings or other non-standard closures.

The good news is that the USPS usually won’t charge you more than once if your card has more than 1 of the above exceptions.  That said, you should always check with your local Post Office, just to be safe.

What is the standard envelope size?

Here is a handy dandy chart for the common greeting card/envelope sizes.   The card sizes are based on an 8-1/2″ x 11″ piece of cardstock.
Tip: you will get 2 cards from every sheet of cardstock for the 4-Bar & A-2 sizes;  1 card for the A-6, A-7, and A-9 sizes.

    • 4-Bar (Notecard)
      Folded Card Size:  3-1/2″ x 5″
      Envelope Size:       3-5/8″ x 5-1/8″
      Cut Your Cardstock at 5″ x 7″ and fold at 3-1/2″
      You can purchase these already cut & scored from Stampin’ Up!  in both White and Vanilla.  They are $7 for 20 cards and envelopes.

    • A-2 (standard greeting card)
      Folded Card Size:  4-1/4″ x 5-1/2″
      Envelope Size:        4-3/8″ x 5-3/4″
      Cut Your Cardstock at 5-1/2″ x 8-1/2″, scored at 4-1/4″ *
      *you can also cut at 4-1/4″ x 11″ and score at 5-1/2″

    • A-6
      Folded Card Size:  4-1/2″ x 6-1/4″
      Envelope Size:        4-3/4″ x 6-1/2″
      Cut Your Cardstock at 6-1/4″ x 9″ and score at 4-1/2″
    • A-7 (common size for Wedding Invitations)
      Folded Card Size:  5″ x 7″
      Envelope Size:       5-1/4″ x 7-1/4″
      Cut Your Cardstock at 7-1/2″ x 10-1/2″ and score at 5-1/4″
    • A-9

      Envelope Size:  5-3/4″ x 8-3/4″
      No need to cut cardstock, score at 5-1/2″
    • Square
      Square is defined by length = width
      5″ x 5″ is the minimum size envelope that can be mailed
      Square envelopes are considered odd-sized and are non-machineable
