Throughout our Help Center, you will see we use some terms when speaking about the quality of the images/files. Below is a bit more information on each of these terms:
Resolution is the measure of pixels in the display, usually expressed in measurements of width x height. For example, a monitor that is 1920 x 1080 is 1920 pixels across and 1080 pixels down.
DPI (dots per inch) is the number of dots in a printed inch. The more dots the higher the quality of the print (more sharpness and detail).
The actual size is best described with (you guessed it) actual numbers. Let's say you have a 5”x5” shape at 100 dpi, but you need to make it a 10”x10”. If you simply scale it to twice its original size you go from 5”x5” to 10”x10” Since the size has now doubled, your resolution has been cut in half - that particular part of your graphic is now 50 dpi.
Our system will automatically check your image resolution when you upload an image file. You can read more about this here.
