In graphic design programs, creating a new file will start a new, independent document using the file’s own settings, while importing brings an external file or asset into your currently active canvas as a new element. When opening a new file you need to decide on resolution and DPI.

What is resolution?

Resolution refers to the number of pixels (px) in an image. For example: 1000 × 1000 pixels = 1 million pixels, 4000 × 4000 pixels = 16 million pixels. Images with more pixels can contain more detail and can usually be printed at larger sizes without losing quality.

What is DPI?

DPI stands for Dots Per Inch. It describes how much detail is printed within one inch of paper. Common values include:

72 DPI – often used for screen-only graphics

150 DPI – suitable for some larger prints

300 DPI – the standard for high-quality printing.

When artwork is only viewed on a screen, pixel dimensions are usually more important than DPI.

What settings should you use?

For artwork that will only be shared online: use dimensions that fit your needs, such as 2000–4000 pixels on the longest side. 72 DPI is usually sufficient. For artwork that may be printed: use 300 DPI.

To asses what resolution you need multiply the desired number of inches by DPI. For example if you need 12×12 inches print of 300 DPI your image resolution need to be 3600×3600 px.

Higher resolution means more pixels so more storage space is required, files take longer to save and load and more memory may be needed while editing. For this reason, it is usually best to choose settings that match the intended use of your artwork rather than automatically selecting the highest possible values.
