And here we see that sure enough, at a resolution of 300 pixels/inch, my image will print 20.053 inches wide and 13.387 inches tall. To view the current print size of your image, change the measurement type for the Width and Height from Pixels to Inches. Viewing the current print sizeĭirectly above the Resolution value in the Image Size dialog box are the Width and Height options. A height of 4016 pixels divided by 300 pixels/inch means that the height of my image, when printed, will be roughly 13.387 inches. And we can do the same thing with the height. So with my image, a width of 6016 pixels, divided by the resolution value of 300 pixels/inch, means that my image will print at a width of roughly 20.053 inches. To figure out the actual print size, we just divide the width and height of the image, in pixels, by the resolution value. It also means that 300 pixels from the height of the image will be packed into every inch of paper from top to bottom. How image resolution affects print sizeįor example, a resolution of 300 pixels per inch means that 300 pixels from the width of the image will be packed into every inch of paper from left to right. And lower resolution values pack fewer pixels per inch, giving us a larger print size. Higher resolution values pack more pixels into a linear inch, resulting in a smaller print size. The Resolution value in Photoshop's Image Size dialog box sets the number of pixels from your image that will print per linear inch of paper. Image resolution does one thing and one thing only it controls the size that your image will print. So let's start by learning what image resolution really means. So what exactly is image resolution, and what does this option in the Image Size dialog box actually do? There's a lot of confusion out there regarding the resolution value, especially when it comes to uploading images to the web.
