8×8

8×8 denotes an eight-by-eight measurement, meaning eight units along one dimension and eight along the perpendicular dimension. As a product, 8×8 equals 64. The term is widely used to describe square grids, matrices, and tiles where both dimensions have eight units.

In board games, an 8×8 grid is famous as the standard chessboard and is also used for checkers and Othello. The board contains 64 squares arranged in eight ranks and eight files; coordinates use a–h and 1–8 to locate squares.

In computing and digital media, an 8×8 pixel matrix is common for simple icons, sprites, and LED displays. 8×8 bitmaps support straightforward rendering in fonts and small images. JPEG image compression, by contrast, operates on 8×8 blocks in its discrete cosine transform stage, making the 8×8 size fundamental in early image processing.

In design and other contexts, 8×8 grids appear in pixel art, cross-stitch patterns, and modular tiling. The term is also used in manufacturing and construction to specify square panels or tiles.
