What is DPI, resolution and actual print file size?

Let’s clarify some terms to help answer your questions:

Resolution refers to the pixel dimensions of a display, typically shown as width x height. For instance, a monitor with a resolution of 1920 x 1080 has 1920 pixels horizontally and 1080 pixels vertically.

DPI (dots per inch) measures the number of dots in a printed inch. A higher DPI means better print quality, providing more sharpness and detail.

Actual size is defined by specific dimensions. For example, if you have a design that is “30cm x 30cm” at 200 DPI and you scale it up to “60cm x 60cm,” you essentially reduce the resolution to 100 DPI, resulting in lower quality.

When submitting print files, please ensure they are at least 150 DPI and at actual size. The resolution is only as effective as the dimensions of the file.
