Photoshop Elements also offers another method of resizing an image. You can use the "crop" function to resize your image quickly. The crop tool looks like a small square with overlapping edges and can also be accessed through the Image menu bar at the top of your screen.
Once the crop tool options bar opens, select "custom" and then enter the desired height/width and resolution. To crop to specific pixels you must enter the letters "px" after the size number in the width/height boxes. If only one dimension is important you can enter information in only one box and let the other dimension be determined purely by where you place the crop line.
After entering your preferences you will click and drag the crop tool across the image to select the part of the image you wish to keep.
