The full form of DPI is Dots Per Inch. It is a measurement of the quantity of dots arranged in a line inside 1 inch or 2.54 cm of width in a video or print image. It technically refers to a printer’s dots per inch.
DPI is a measurement of how sharp the touchscreen display is in computers. The number of ink dots a printer can fit into a square inch in terms of printing corresponds to an indicator of the printed image’s effectiveness on the paper or the printer’s resolution. The resolution improves with the number of dots per centimetre.

- DPI is frequently used to assess the print quality of digital images and demonstrate the printer’s performance.
- The amount of coloured dots that can fit into a one-inch frame provides information on an image’s resolution.
- The resolution of the printer or scanner is thus measured in dots per inch.
- For example, a printer with a resolution of 400 has 400 dots up and down each row.
- If there are many more dots per inch, there will be less space between them. As a result, colour droplets can be merged to produce high-quality images.
- The closer they are, the sharper the image is, so if you want to print sharp and clear pictures, the DPI should be significant.
