11x11

11×11 denotes a square grid composed of 11 units on each side, yielding 121 individual cells. In arithmetic, the expression 11×11 equals 121, and the term 11 squared is used to describe this value. When 11×11 is used to describe a matrix, it refers to a two-dimensional array with 11 rows and 11 columns; such a matrix is square and has properties that depend on its entries, such as determinant and invertibility.

In puzzles and games, 11×11 grids appear as playing fields or canvases for custom puzzles, including certain crossword variants, nonograms, and Sudoku-style challenges that use eleven-by-eleven layouts instead of the standard sizes.

In computing and image processing, 11×11 is a common size for convolution kernels. An 11×11 kernel contains 121 coefficients and is applied to an image to compute local features, with a larger footprint than the more common 3×3 or 5×5 kernels.

As a data structure, an 11×11 array can store two-dimensional data such as small images, game boards, or tabular values. Operations typical of two-dimensional arrays—iteration by row and column, transposition, and matrix arithmetic when embedded in larger computations—apply to this shape.

There is no single universal meaning for 11×11; its interpretation depends on the context, but it consistently describes a square dimension with eleven units per side and 121 elements in total.
