The postcards are almost finished! I stayed up to late, but I am happy they are almost done! Now, I just need to make the guest list - yikes!
This info was helpful -
Minimum Allowable Postcard Size: 3.5 x 5 InchesIf the width is less than 5 inches or the height is less than 3.5 inches the USPS will NOT mail your postcard.
Maximum Allowable Postcard Size: 4.25 x 6 InchesIf the width is greater than 6 inches or the height is greater than 4.25 inches, the postcard must be mailed as a letter, higher rate and all.
Minimum Thickness: .007 Inches
Any mail less than the minimum is considered Non-Mailable and the USPS will NOT deliver it.
Maximum Thickness: .25 inches
Exceeding the maximum puts the mail piece into a different mail class, called a Parcel.
Intermediate Sizes are Allowable
A 4 x 5.5 inch postcard is mailable at the postcard rate. As long as a mail piece meets the size, thickness, weight and aspect ration requirements above, it can be mailed as a postcard.
...and this site - USPS - was helpful too!
Wow - this image will help me make sure nothing is covered up as I finish the back of the postcard!
