Note that because you'll be changing the physical size of the image, pixels as measurement units will be grayed out. This way, changing the resolution will automatically change the print dimensions and vice versa, ensuring the pixel size of the image stays the same. Note: If you’d like to change the print dimensions of an image without changing the quality of the image (or its pixel dimensions), deselect the Resample checkbox. So, if you have a 10x10 inch image at 300 PPI, its pixel size would be 3000x3000.

The basic formula for this is Print Size x Resolution = Pixel Dimensions. When you change the print dimensions of an image, you’re essentially changing its pixel dimensions indirectly by letting Pixelmator Pro calculate the size for you. Note: If you’d like to resize the image without keeping its original proportions, deselect Scale proportionally. Choose a print unit (inches, cm, mm, or points) from the Unit pop-up menu.Įnter a new width and height for the image or use text field math to calculate it.Press Option ⌥ + Command ⌘ + I on your keyboard.Choose Image > Image Size (from the Image menu at the top of your screen).
