Tabloid or U.S. Newsprint is the name for paper that is 11 inches wide and 17 inches long. B, short grain, or ANSI B. The paper that is 17 inches wide and 11 inches long is called ledger or long grain, but it is still U.S. B and the ANSI B.
From E to A, the American National Standards Institute says there are five different sizes of paper. Each size down is half as big as the one before it. The E size, which is 44 inches long and 34 inches wide, is the biggest. The next size up is D, which has a length of 22 inches and a width of 34 inches. One-eighth of an E size is a B size, which is 11 inches wide and 17 inches long. The only thing that doesn’t follow this rule is the size of a government letter, which is 8 inches wide and 10.5 inches long.
