Using Adobe Illustrator, I’ll demonstrate how to create a rounded rectangle.
Basically, Adobe Illustrator has a tool that allows you to create rounded rectangles.
For that, you will have to change the Adobe Workspace from Essential to Essential Classic.
Go to the Switch Workspace option near the search bar in the right upper corner of Illustrator.
Go to your left-hand side toolbar and find the “Rectangle Tool”.
Right Clik on it, a pop-up menu will appear.
As you can see there is a “Rounded Rectangle Tool”.
Click on this tool.
Method 1: Click and drag on the artboard
Click and drag on your artboard, you will notice a rectangle with rounded corners.
Note: Don’t release the mouse left button.
Now, press the keyboard up and down arrow keys. Pressing one time these keys, Rectangle will change the radius by 1px.
you can also press the left and right arrow keys. These keys will change the radius to 0 or half of the size of the rectangle.
Method 2: By Dialog box options
Select the rounded rectangle tool.
Make sure you click on the artboard rather than dragging it.
Rounded Rectangle Dialog box will appear.
Enter your desired value in the corner radius option.
