There are a few ways to resize a background in Photoshop. The easiest way is to use the resize tool on the left side of the screen. You can drag and drop the background onto the canvas, or use the buttons on the right side of the screen to resize it in specific ways. If you want to make a larger background, you can use one of Photoshop’s built-in backgrounds. Or you can create your own using one of Photoshop’s templates.
