Image DPI and PPI Calculator Online
Use this free calculator to estimate how large an image can be printed at a selected DPI or PPI based on its pixel dimensions.
Calculate Print Size from Pixels and DPI
The basic formula is pixel width divided by DPI for print width in inches, and pixel height divided by DPI for print height in inches.
Find Required DPI for a Print Size
You can also enter a target print width and height to estimate the horizontal and vertical DPI needed for that print size.
