In this article, let’s talk about how to use the Rectangular Marquee tool in Photoshop.
Where is the Rectangular Marquee tool?
The Rectangular Marquee Tool is at the top of the Photoshop Toolbar below the Move tool. Its icon resembles a square’s perimeter. You can click the Elliptical Marquee Tool to read about another selection tool.
How to make a selection by Rectangular Marquee tool?
The working method is: you start from the upper and left part of the area you want to select. Hold the mouse button down exactly from that part and move the mouse down and right to cover the desired area completely. To complete the selection, release the button.
You will see a rectangle-shaped, selected area with dotted sides..
If the selection is wrong, use the Rectangular Marquee tool to move it by clicking above it. In this case, the pointer becomes an arrow and a rectangle.
If the selected area is no longer needed, you can unselect it. To do this, you can choose Deselect from the Select menu. Alternatively, you can use the shortcut key Ctrl + D much more easily.
Or click Deselect from the Contextual Task Bar.

How to select a square region in Photoshop?
When you select this tool, the Options Bar related to the Rectangular Marquee tool in Photoshop appears at the top of the screen. In this Option Bar, there is a section called Style. If you set Style to Fixed Ratio and set Height and Width to 1, then the tool will select a square area.
Return the style settings to Normal after you’re done, otherwise the tool will still select a square for you.
Shortcut key for selecting square shape
An easy way to create a square selection area is to use the Shortcut Key. After selecting the Rectangular Marquee tool, hold down the shift key, press the mouse button, and drag. After following the steps, you will have drawn and selected the square. Finally, release the mouse button and then release the shift key.
Draw a selection starting from the center
In normal mode, we drag from the left and top point. To drag from the center, first hold down the Alt key, then hold the mouse button and draw. Once you’re finished, release the mouse button and the Alt key.
To select the square from the center while drawing, press and hold the Shift and Alt keys, click the mouse button, and drag.
When Should You Use the Rectangular Marquee Tool? (Real Use Cases)
The Rectangular Marquee Tool is best used when you need clean, straight-edged selections.
It’s ideal for editing areas that naturally fit into rectangular or square shapes.
Here are common real-world scenarios where this tool is the fastest and cleanest option:
- Cropping or isolating banners, posters, and signs
- Selecting UI elements, buttons, or interface parts in screenshots

Tip:
If the object has complex edges, use the Rectangular Marquee Tool to block the main area first, then refine with selection refinement tools.
