11x17 paper is commonly known as "Tabloid," "B-Size," or "Ledger" size paper. It is a larger size paper that provides more printing space and is ideal for detailed architectural, construction, and engineering drawings. This size of paper is usually used in offices that require large-sized documentation that would not appropriately fit on a standard Letter size paper. It is also used in magazines to fold and compile multiple sheets together as well as in printing posters. The official name for 11x17 paper size is ANSI B size.
