How do I set the maximum line length in PyCharm?

I am using PyCharm on Windows and want to change the settings to limit the maximum line length to 79 characters, as opposed to the default limit of 120 characters.

Where can I change the maximum amount of characters per line in PyCharm?

You can also make use of editorconfig and create the .editorconfig file in the root of the project with content like this:

# top-most EditorConfig file
root = true

[*.py]
max_line_length = 80

You can also replace [*.py] with [*] to apply this config to all files (not only to python files).

Note: This worked for me on PyCharm Professional 2024.1.1.

For PyCharm 2018.1 on Mac:

Preferences (⌘+,), then Editor -> Code Style:

enter image description here

For PyCharm 2018.3 on Windows:

File -> Settings (Ctrl+Alt+S), then Editor -> Code Style:

To follow PEP-8 set Hard wrap at to 80.

For anyone, or myself if I reload my machine, who this is not working for when you do a code reformat there is an additional option to check under editor->code style->python : ensure right margin is not exceeded. Once this was selected the reformat would work.

For PyCharm 2017

We can follow below: File >> Settings >> Editor >> Code Style.

Then provide values for Hard Wrap & Visual Guides for wrapping while typing, tick the checkbox.

NB: look at other tabs as well, viz. Python, HTML, JSON etc.

You can even set a separate right margin for HTML. Under the specified path:

File >> Settings >> Editor >> Code Style >> HTML >> Other Tab >> Right margin (columns)

This is very useful because generally HTML and JS may be usually long in one line than Python. :)

For PyCharm 4

File >> Settings >> Editor >> Code Style: Right margin (columns)

suggestion: Take a look at other options in that tab, they're very helpful
