DPI stands for "dots per inch" and refers to the resolution or clarity of an image or document. It is a measure of how many dots can fit into a one-inch space.
DPI is calculated by dividing the number of dots in the horizontal direction by the width of the image or document in inches. The same calculation is done for the vertical direction.
DPI is important because it affects the quality of an image or document. Higher DPI means more dots per inch and therefore a clearer and more detailed image. Lower DPI can result in a blurry or pixelated image.
The standard DPI for printing depends on the type of printing and the desired quality. For commercial printing, the standard is usually 300 DPI, while for home or office printers, it can range from 150-600 DPI.
Higher DPI images have more dots per inch, which means they have more information and therefore a larger file size. This is important to consider when printing or sharing images, as larger file sizes can take longer to load or may not be compatible with certain devices or platforms.
