Increase font size in Emacs on Linux

As an Emacs user, you may find that the default font size on the current buffer or global buffer is not exactly suitable for your needs. Sometimes you may feel that the font size is too large or too small, which affects your ability to read the text clearly. Knowing how to adjust font size can make it easier for you to work with text content and avoid eye strain. There are several ways to adjust font size in Emacs on Linux systems, and this article will introduce some of the best options for you to use.

Two methods to increase Emacs font size on Linux

Some users may feel that the default font size in Emacs is already appropriate, but if you think the font is too small, you can easily adjust it to a size that better suits you. Browse through the various discussed methods to find the one that works best for you to increase font size.

Method 1: Use key combinations

It is common to use shortcut keys to complete various tasks in Emacs. For example, to adjust the font size, you can easily do it with a key combination. Emacs is actually a powerful and highly customizable editor that allows users to complete their work more efficiently.

We use the following buffer, which contains three lines of text:

To increase the font size, press "C—x c—". The shortcut means you press the "Ctrl" key, then press x, release x, then press the " " key, gradually increasing the font size until you get a comfortable font size that gives you the best visibility.

Pressing the key combination will only change the font size in the current buffer, and this change is only temporary. The following example will show how to adjust the font size in the buffer:

After increasing the font size, you may also want to decrease the font size to control text size. We use the same key combination, but instead of pressing " " we press "-" until we get the desired font size. Use the "C-x C-" keys. Notice how as you continue to press "C-" the font size keeps decreasing, even below the default font size.

To return to the default font size, press "C-x C-0". The buffer will use the default font size, which is Emacs' global font size.

Method 2: Use commands to adjust the current buffer

Emacs has a "text-scale-adjust" command that can interactively adjust the font size of the current buffer. To use this feature, perform the following steps in Emacs with any buffer open: Press the "M-x" (Alt x) key combination and type "text-scale-adjust".

After pressing the RET/Enter key, you will get an output showing how the text is resized. You can use " " to increase the font size, "-" to decrease the font size, or 0 to restore the font size.

For our case, we want to increase the font size. In this case, press the "Ctrl" and " " keys simultaneously and continue pressing the " " key to interactively increase the font size. Make sure you still hold down the "Ctrl" key when pressing the " " key.

If you want to reduce the font size, add the same "Text-Scale-Adjust" command and then press "Ctrl" and "-" to reduce the font size. Keep pressing "-" until you have the font size you like.

You can also press "Ctrl 0" when running the "Text-Proportion-Adjust" command to quickly restore the font size.

Method 3: Permanent Solution

The final way to increase the font size in Emacs is to set the preferred font size in the Emacs configuration file.

Find the configuration file. It is "~/. emacs" or "~/. emacs. d/init. el". Next, add the following statements:

(set—face—attract ‘default nil: height 120)

He said:

The given statement sets the font size to 12 points. Feel free to adjust it as you see fit. Finally, save the configuration file and restart Emacs. This way Emacs will increase your font size based on the properties you specify in the configuration file.

in conclusion

Emacs allows users to adjust the font size of the global buffer or the current buffer. This guide provides three methods you can use to increase the font size in Emacs on Linux. Try each method to see which one works best for your needs and stick with it.
