What does DPI mean?

DPI stands for "dots per inch" and is a measure of the resolution of an image. It refers to the number of dots or pixels that are printed in one inch of an image. The higher the DPI, the more pixels there are in a given area, and the higher the image resolution. The concept of DPI is commonly used in printing, where images are reproduced on paper or other materials.

The DPI value is a critical factor in determining the quality of an image when it is printed. A higher DPI value will generally result in a more detailed and sharper print, while a lower DPI value will result in a more pixelated and blurry print. A DPI value of 300 is generally considered the standard for high-quality printing, but the ideal value can vary depending on the intended use of the image.

It is important to note that DPI and image size are not the same thing. Image size is the physical dimensions of the image in inches or centimeters, while DPI is a measure of the amount of detail in the image. For example, an image that is 4 inches by 4 inches at 300 DPI has a higher resolution than an image that is 4 inches by 4 inches at 72 DPI.
