1000by1000

1000by1000 is a designation for a square two-dimensional size with 1000 units along each axis. In digital contexts it most often refers to a 1000-by-1000 pixel image or canvas, yielding a total of 1,000,000 pixels. The term can also describe a grid or matrix with 1000 rows and 1000 columns, resulting in a million elements.

Applications include images and graphics; 1000x1000 images are common in tutorials, benchmarking, and user interface design because the size is large enough to show detail while remaining manageable. In image processing, operations over 1000x1000 arrays are typical for testing algorithms such as filtering, convolution, or compression. Memory usage depends on color depth: a 1000x1000 RGB image stored with 24 bits per pixel uses about 3 megabytes; with RGBA at 32 bits per pixel about 4 megabytes.

In mathematics and computer science, a 1000x1000 matrix is a common example size for discussing algorithms and data structures. It also appears in game development and spatial indexing as a grid resolution for maps or tiles, though actual applications vary by domain.

Variations in phrasing include "1000×1000" or "1000 by 1000." The concept emphasizes square geometry, where the width equals the height. Related concepts include resolution, aspect ratio, and pixel density.
