ENVELOPE SPECIFICATIONS
Design your insert after you choose an appropriate envelope size. To do the reverse, and request an off-size envelope to fit an insert, can be costly. Standard sizes are always cheaper and more readily available from your printer.
When determining measurements, designers tend to “crowd” the insert. Leave ¼” on either side of your insert (i.e., make sure the envelope is ½” longer than the long dimension of your insert). Leaving ¼” between the top of the insert and the opening of the envelope should provide adequate space along this dimension. However, if your insert is thick, leave more space than usual. If it is very thin, you can usually get away with 1/8” leeway on all sides. It’s always best to make an accurate mock-up and try it out before you proceed.
All envelopes must be rectangular. Non-standard shapes are usually not mailable (there are some exceptions to this rule, although irregular shapes cannot be machine processed). Check with your postal representative to determine the proper aspect ratio (ratio of length to height) for envelopes.
Deciding whether to use “open end” (flap on the short dimension) or “open side” (flap on the long dimension) envelopes can be tricky. If your mailing materials will be inserted into the envelopes by machine, choose open side. If your materials will be hand inserted, you can choose either option.
