64x64

64x64 denotes a two-dimensional size in which both the width and the height are 64 units. Commonly read as “64 by 64” or “64 times 64,” the value 64 is a power of two (2^6), a property that is relevant in computing and digital graphics.

Mathematically, the area is 4,096 square units, the perimeter is 256 units, and the diagonal length is 64√2, approximately 90.51 units. Being a square, opposite sides are equal and all angles are right angles.

In digital media, 64x64 is a widely used dimension for small images such as icons, sprites, and texture tiles. Power-of-two sizes simplify memory management and hardware acceleration, making 64x64 convenient for texture atlases and mipmapping. Uncompressed storage can be estimated as 64×64 pixels; at 24-bit color the raw data is about 12,288 bytes, and at 32-bit color about 16,384 bytes.

Typical applications include icon libraries, user interface elements, and 2D game assets. In tile-based mapping and pixel art, 64×64 tiles or sprites are common, especially in retro-inspired projects. 64x64 grids are also used in LED displays and some scientific imaging workflows as a manageable, compact block.
