Dot Pitch

On a computer monitor, a measure of the size of a screen pixel, or dot, measured in millimeters. For example, a monitor with a dot pitch of .28 contains dots that are .28 millimeter across. Dot pitch, though not specifically a measure of resolution per se, is what determines the resolution of a particular screen. The dot pitch is governed by the size of the raster scan line and the spacing of the shadow mask. The smaller the dot pitch, the more dots can fit per inch, and the greater the resolution.

The term dot pitch, when used to describe a computer printer or other output device, is synonymous with the dots per inch, or resolution. See Resolution.
