Select the Line tool
Create lines and arrows using the Line tool in Photoshop.
The Line Tool allows you to draw a two-point line on the canvas. Lines can be drawn as vector shapes, paths, or pixels. Choose Shape mode if you want to make a non-destructive, scalable line that you can edit at a later date. Choose Pixels mode when working with rasterized content such as pixel art.
Follow these quick steps to draw a line:
Select the Line tool
From the toolbar, click and hold the Shape tool () group icon to bring up the various shape tool choices. Select the Line tool.
Set the width of your line
The weight of a Shape line can be adjusted with both Stroke and Weight settings in the Options bar.
Choose the width of your line in the options bar by setting the desired Stroke size with Weight set to 0. For best results, ensure the Align setting in the Stroke options is set to Center or Outside. The stroke weight will not be visible if Inside alignment is selected. Alternatively, you can set the width of your line using Weight in the options bar with or without a stroke.
