512x

512x is a shorthand notation used in digital media and computing to indicate a dimension of 512 pixels along one axis. It is typically read as "512 by X," with the second dimension specified to form a complete resolution (for example, 512x512 or 512x256).

The "x" stands for "by" or multiplication in the width-by-height convention. This format is used across image, video, and graphics workflows to describe the size of a canvas, texture, icon, or render target. It helps communicate how many pixels an asset contains and how it will fit into a pipeline.

Common contexts include texture maps and sprite sheets in video games, square icons, and thumbnail images. Using consistent dimensions such as 512x512 provides predictable memory usage, alignment in sprite grids, and easier scaling or mipmapping decisions. It also reflects a balance between visual fidelity and performance on varying hardware.

Limitations: specifying only 512x does not define the aspect ratio or the full resolution; the missing dimension must be known. In practice, 512x values are chosen to fit specific design goals, performance constraints, or hardware texture-size limits.
