Step by Step Tutorial: How to Draw a Straight Line in Adobe Photoshop

The following steps will guide you through the process of drawing a straight line in Adobe Photoshop using the Line Tool.

Step 1: Select the Line Tool

Select the ‘Line Tool’ from the toolbar on the left side of the screen or press ‘U’ on your keyboard to access it quickly.

The Line Tool is specifically designed for creating straight lines. It’s found in the same group as the Rectangle and Ellipse Tools, so you might need to click and hold the shape tool icon to reveal it.

Step 2: Configure the Line Tool Options

Before drawing, set your desired line weight, color, and style in the options bar at the top of the screen.

In the options bar, you can choose the line’s thickness by setting the ‘Weight’ and select the color by clicking on the color box. You can also decide whether the line should have arrowheads at either end.

Step 3: Draw the Line

Click and drag on your canvas to draw the line. Release the mouse button to finish the line.

As you drag, a preview of the line will appear, showing you exactly where it will be placed. You can adjust the line’s length and angle by moving the mouse before releasing the button.

Step 4: Hold Shift for a Perfectly Straight Line

Hold the ‘Shift’ key while dragging to constrain the angle and make the line perfectly horizontal, vertical, or at a 45-degree angle.

The ‘Shift’ key is crucial for precision. By holding it, you ensure that your line is not only straight but also aligned perfectly with your image’s axes.
