If you want to resize a selection in Photoshop, there are a few different ways to go about it. One way is to use the Selection tool (V), and then use the resize handles (bottom-left and bottom-right of the selection box) to resize the selection. Another way is to use the Edit menu (E), and then select Resize. This will open up the Resize dialog box, where you can specify how much you want to resize the selection by entering a new width or height value in pixels. ..
