How to Draw a Straight Line in Adobe Photoshop

Photoshop provides you with a large selection of tools that you can use to edit pictures that you have opened in the application. Whether it’s a picture that you took yourself with a camera, or one that you got from someone else, Photoshop makes it easy to crop the picture, change its dimensions, or perform a number of different adjustments to improve the look of the image.

But Photoshop also has a lot of tools that help you add new objects to that image, such as a line. In our tutorial below we will discuss how to draw a line in Photoshop using the Brush tool.

How to Draw Lines With Photoshop’s Brush Tool

The steps in this article were performed in Adobe Photoshop CC, version 20.0.1, but these steps are nearly identical in almost every other version of Photoshop.

Step 1: Open your image in Photoshop.

Step 2: Select the Brush tool from the toolbox at the left side of the window. Note that you can also simply press the “B” key on your keyboard while in Photoshop to automatically switch to this tool.

Step 3a (drawing a horizontal line): Hold down the Shift key, click at the desired starting point and hold down your mouse button, then drag it to create the horizontal line. Note that this will also work for vertical lines, you just need to drag your mouse down or up instead of left or right.
