320×240

320×240 refers to a display resolution with 320 pixels across and 240 pixels down, for a total of 76,800 pixels. It is commonly known as QVGA, short for Quarter VGA, because it is one quarter of the VGA resolution of 640×480. The aspect ratio is 4:3, which was standard for many early displays.

This resolution was widely used on mobile devices, personal digital assistants, and portable media players from the late 1990s into the mid-2000s. It offered lower memory usage and power consumption compared with higher resolutions of the era, making it practical for battery-powered handhelds. Color depth varied by device, with common configurations including 16-bit color (approximately 65,536 colors) and 8-bit palettes; some devices used 24-bit color.

In practice, 320×240 is well-suited to smaller screens, such as those around 3.5 inches or smaller, delivering a reasonably sharp image for its time. However, the 4:3 aspect ratio is not ideal for modern widescreen content, which often results in letterboxing or the need for image scaling. Today, 320×240 is mostly of historical interest but remains in use in certain embedded systems, legacy hardware, and some retro or budget devices. It is frequently referenced in documentation and specifications as a category of lower-resolution display used by early mobile and handheld devices.
