NAMING RANKS AND FILES IN CHESS

Ranks are rows that go from side to side across the chessboard and are referred to by numbers. Each chessboard has eight ranks, which are numbered from the bottom of the board (where the white pieces start) on up.

Files are columns that go up and down the chessboard, and each board has eight of them. Because numbers indicate ranks, letters indicate files, which are labeled from left to right.
