This contains a list of commonly used sizes which you can select. Photoshop then displays the “Image Size” dialog which you can see below.īelow this list is another dropdown titled “Fit To”. Then click the Photoshop “Image” menu and the “Image Size…” submenu option. Start by opening the image you want to resize in Photoshop. Now you understand the importance of pixels and resolution, let’s look at where we use this when resizing an image in Photoshop. If the image is too big or too small, it’s going to cause problems. What’s important are the pixel dimensions (height and width) of the image. When that happens, the resolution is ignores in most cases. That’s because most images now only appear on computer screens and the internet. Whilst this is useful information if you are going to print an image, most of the time you don’t need it. If an image is 5,616 pixels wide with a resolution of 300ppi, it would produce a print 18.72 inches wide that’s 5,616 pixels divided by 300. You just need to divide the dimensions of the image by the resolution: When you know the number of pixels and the resolution, you can calculate the size of the image in inches. This is the number of pixels in an inch if we were to print the image. The “ppi” after the number stands for Pixels Per Inch.
Usually this is written as a figure like 96ppi or 300ppi. The resolution of the image tells us how many pixels there are to each inch or centimetre. But if we wanted to state it’s size in centimetres or inches, we need another piece of information first.
