It's embarrassing to say how long I've been using GIMP without knowing how to draw a straight line, but ... skipping that ... here’s a quick tutorial on how to draw a straight line with GIMP.
GIMP straight line: Step 1
Step 1 is to have an image you want to draw a straight line on. I’ll assume you have a practical image to work on, but for my purposes I’ll draw a straight line in black on a white canvas. Here’s my white canvas:
The next step to draw a straight line is to select your painting tool. I’m going to use GIMP's Paintbrush Tool, but you can draw a straight line with any of the following tools:
- Paintbrush Tool
- Pencil Tool
- Airbrush Tool
- Ink Tool (Calligraphy tool)
- Smudge Tool
- Dodge/Burn Tool
I just tested all of these tools, and they work fine on my GIMP 2.6.3 system.
After selecting your drawing tool, in Step 3 all you have to do is select a starting point for your straight line. Just click your image once wherever you want your straight line to start:

It looks something like this:
Once you’ve decided where you want your straight line to end, just click that spot on your image (left-click), while still holding down the [Shift] key. After you click the mouse button, you’ll have a straight line, something like this:
That’s all you have to do.
Somehow I managed to work with GIMP a long time without knowing this, but it’s a huge time-saver once you find it.
