lettersized

Lettersized refers to media designed to the Letter size standard, usually paper. The Letter size, also known as ANSI Letter, measures 8.5 by 11 inches (216 by 279 millimeters) and is the default paper size for many office documents in the United States and Canada. The term is commonly used in printing, copying, publishing, and mailing to indicate compatibility with devices, software settings, and workflows that assume this size.

In practice, lettersized media is often contrasted with other common sizes. The most widely used international alternative is A4, which measures 210 by 297 mm. Other related sizes include Legal (8.5 by 14 inches) and Tabloid/Ledger (11 by 17 inches). Printers and copiers typically offer Letter presets, and many word processors provide margins and templates tailored for Letter size by default.

Applications of lettersized materials include standard documents, forms, letters, and reports. In mailing, “letter-sized mail” describes items that meet postal size and weight limits for letter-rate postage; items that are heavier or thicker may be classified as flats or parcels.

Overall, lettersized remains the dominant paper size for business and personal documents in North America, shaping conventions in document design, printing, and mailing. Its use is regionally specific, with other parts of the world preferring ISO A-series sizes.
