At what resolution are images on the web typically viewed?

Images on the web are typically viewed at a resolution of 72 dpi (dots per inch). This standard has been established due to the display capabilities of screens, which generally do not require a higher resolution for optimal viewing. At 72 dpi, images can be rendered clearly on monitors without unnecessarily large file sizes, which would slow down loading times. Higher resolutions like 300 dpi are more suitable for print media, where finer detail is needed, while values such as 150 dpi and 680 dpi are less common for web use, as they would also result in larger file sizes that are not conducive to quick web performance. Thus, choosing 72 dpi is practical for clarity and efficiency in web graphics.
