How to Increase Line Length in VS Code's Pylint: A Step-by-Step Guide (2026)

Visual Studio Code (VS Code) is a popular code editor that supports Python development through various extensions, including Pylint, a static code analysis tool. By default, Pylint enforces a maximum line length of 80 characters, which aligns with PEP 8, the official Python style guide. However, some projects may require longer lines, and adjusting this setting can improve readability and fit specific coding standards.

In this guide, we'll explore how to increase the line length in VS Code's Pylint. This process involves modifying the Pylint configuration to fit your project's needs. We'll address common issues that may arise and provide troubleshooting tips to ensure a seamless experience.

Key Takeaways

• Learn how to modify Pylint's max line length setting in VS Code.
• Understand why line length settings are crucial for code readability.
• Discover how to troubleshoot common configuration issues.
• Explore best practices for maintaining code style consistency.

Prerequisites

• Basic understanding of Python and coding standards like PEP 8.
• VS Code installed with Python and Pylint extensions (version 2026 or later).
• Access to a Python project where you can test the configurations.

Step 1: Install or Verify Pylint Installation

Before modifying settings, ensure that Pylint is installed and operational in your VS Code environment. Pylint is typically included with the Python extension, but if it isn't, you can install it via pip.

pip install pylint

Once installed, verify its functionality by linting a Python file.

pylint your_script.py

If Pylint reports issues, you're ready to proceed.

Step 2: Modify VS Code Settings

To change the line length in Pylint, you need to modify the VS Code settings file. Open the settings (File > Preferences > Settings) and search for 'pylintArgs'. You can directly edit the settings.json file for more advanced configurations.

{
  "python.linting.pylintArgs": [
    "--max-line-length=120"
  ]
}

This setting instructs Pylint to allow lines up to 120 characters, overriding the default 80.

Step 3: Verify Configuration Changes

After adjusting the settings, verify that the changes are effective by reopening or re-linting a Python file with lines exceeding 80 characters. Pylint should no longer flag these as issues.

Check the editor's Problems tab or the output panel for validation.

Step 4: Use a .pylintrc File for Project-Specific Settings

For projects with specific style requirements, using a .pylintrc file can be beneficial. This configuration file, placed in the root of your project, can store settings that apply only to that project.

[MASTER]
max-line-length=120

Create this file and add the above configuration to ensure consistency across all team members' setups.

Common Errors/Troubleshooting

• Ensure the correct path to settings.json is used (User vs Workspace settings).
• Verify that no other configurations override the max-line-length setting.
• Restart VS Code if changes do not take effect immediately.
• Check for Pylint updates that might affect configuration options.

By following these steps, you can effectively increase the line length in VS Code's Pylint, allowing for more flexibility in your coding style. This adjustment can aid in maintaining code readability and consistency across various projects.

Frequently Asked Questions

Why is the line length in Pylint set to 80 by default?

The default line length of 80 characters is based on PEP 8 standards for readability and maintaining code consistency across different environments.

Can I set different line lengths for different projects?

Yes, using a .pylintrc file in each project's root directory allows you to specify project-specific configurations.

What if changes to settings.json don't take effect?

Ensure there are no overriding settings elsewhere and try restarting VS Code to apply changes.
