Envelopes should comfortably contain your desired contents. Ideally, allow at least 1/4" clearance from top to bottom and allow more room for multiple or thick inserts.
To receive "best" machinable rate discounts for first class and standard mail letters, the length of the envelope must be 1.3 to 2.5 times its height.
