Narrower

Add margins to wide pages.

Narrower is a lightweight Chrome extension that helps users manage annoyingly wide web pages by adding adjustable margins. Simply click the Narrower icon and drag the slider to narrow the content area with added margins, making wide sites easier to read and navigate.

Narrower works by dynamically changing the padding of the document's root element (<html>) and saves your preferred margin settings per site in localStorage. These settings persist on each visit, ensuring a consistent, user-friendly browsing experience. If needed, you can reset margins by dragging the slider back to 0% and refreshing the page. While it works on the majority of sites, some webpages may not respond as expected due to CSS constraints, in which case adjusting your browser window size manually may be an alternative.

User reviews

Narrower is a simple and effective Chrome extension that improves reading comfort by narrowing wide webpage layouts, especially beneficial on ultrawide monitors and for reading ebooks in HTML format. Users appreciate its straightforward functionality and compatibility with other readability tools. However, many users request features to save settings per website and automatic activation to avoid repeated manual toggling. Some also noted compatibility issues with Chrome Beta due to Manifest V3. Overall, it is valued for enhancing reading experiences on wide screens but could benefit from added persistence and automation features.
Pros
  • Effectively narrows wide webpage content for easier reading and reduces eye strain.
  • Simple, no-frills design that works as expected without annoyances.
  • Highly useful for reading formatted ebooks and articles on ultrawide or widescreen monitors.
  • Works well in combination with other readability extensions like line height adjusters.
  • Provides a quick and convenient way to center and control text width, improving the reading experience.
Cons
  • Lacks the ability to remember or save settings on a per-website basis, so users must re-enable it repeatedly.
  • Does not automatically enable on specific websites, requiring manual activation each time.
  • Compatibility issues with Chrome Beta and Manifest V3.
  • No persistent mode or keyboard shortcut mapping to maintain settings or easily toggle the extension.

Extension safety

Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Narrower does not require any sensitive permissions.

Risk impact analysis details
    Risk likelihood
    Risk likelihood measures the probability that a Chrome extension may turn malicious. This is determined by the publisher and the Chrome extension reputation on Chrome Web Store, the amount of time the Chrome extension has been around, and other signals about the Chrome extension. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Chrome extension.

    Narrower is probably trust-worthy. Prefer other publishers if available. Exercise caution when installing this extension.
