Most invitations and cards come in sizes that fit perfectly in 5×7 envelopes. You should use these envelopes to hold cards with corresponding measurements, especially since the compact, square shape and size can look very appealing. Do you need extra postage for 5×7 envelopes? Typically, no, you should not need extra postage. The postage amount will typically depend on the envelope’s weight rather than its size. As long as the envelope and its contents do not exceed one ounce, you shouldn’t need extra postage when mailing. Be sure to check with your local postal office. Can I print on 5×7 envelopes? Yes. But some envelopes are much thicker than others and cause jamming issues in some printers. As long as your envelope is not too thick for the printer, you will be able to print on 5×7 envelopes just fine. Just make sure your printer is set up to print on the 5×7 measurements, and always check the placement on a plain piece of paper before going ahead with your actual envelopes.
