Can you mail any shape envelope?
+
Yes, but only within USPS size and machinability rules. Irregular envelopes can be mailed if they still fit the limits for thickness, aspect ratio, and flexibility. If the shape is too unusual, too rigid, or has protruding parts, it may be treated as nonmachinable and charged at a higher rate. A first class mail shape based template helps check whether the piece stays within the standard letter or flat category before printing and mailing.

What are the dimensions for first class mail?
+
For First-Class Mail, letter-size pieces are typically between 5 and 11.5 inches long, 3.5 and 6.125 inches high, and up to 0.25 inches thick. Flats can be larger, up to 15 inches long, 12 inches high, and 0.75 inches thick. Weight also matters: First-Class Mail letters and flats generally can weigh up to 3.5 ounces, with postcards and parcels following different limits.

What is letter-shaped mail?
+
Letter-shaped mail is a piece that matches the USPS letter format: rectangular, flexible, and within the standard size and thickness limits for automated processing. It usually has a uniform shape, readable address placement, and enough rigidity to pass through sorting equipment. A first class mail shape based template is often used to confirm that a design fits these requirements before production, especially when preparing postcards, reply cards, or promotional mailers.

Why does a square envelope cost more to mail?
+
A square envelope costs more because it is harder for automated sorting equipment to process. USPS treats square mail as nonstandard, which can trigger a nonmachinable surcharge or a higher postage rate. The shape also reduces feeding efficiency and may require manual handling. When using a first class mail shape based template, square formats can be checked early so the final piece stays within the most economical mailing category whenever possible.
