React Scrollbar and Scroll Management: A Practical Comparison

When building polished React UIs, developers often encounter limitations with native scrollbars—especially their inconsistent appearance across browsers and operating systems. Other times, the need isn’t visual but behavioral: smoothly scrolling to sections, measuring scrollbar dimensions, or handling scroll events reliably. The packages rc-scrollbars, react-custom-scrollbars, react-perfect-scrollbar, react-scroll, and react-scrollbar-size each solve distinct problems in this space. Let’s break down what they do, how they differ, and where they fit in real-world apps.

🖼️ Custom Scrollbar Rendering: Replacing Native Scrollbars

Three of these packages aim to replace the browser’s default scrollbars with styled, consistent alternatives. However, their approaches and trade-offs vary significantly.

rc-scrollbars: Modern, Minimal, and React-Native

rc-scrollbars is built specifically for React using modern patterns. It avoids external dependencies and uses React’s own event system and refs for efficient updates. It supports auto-hide, thumb dragging, and works well with dynamic content.

import { Scrollbars } from 'rc-scrollbars';

function App() {
  return (
    <Scrollbars style={{ height: 300 }}>
      <div>Long content here...</div>
    </Scrollbars>
  );
}

It exposes render props for customizing track and thumb elements, enabling full design control:

<Scrollbars
  renderThumbVertical={({ style, ...props }) => (
    <div {...props} style={{ ...style, backgroundColor: '#888', borderRadius: '4px' }} />
  )}
/>

react-custom-scrollbars: Deprecated and Outdated

This package is officially deprecated (as noted on its npm page and GitHub repo). It hasn’t been updated in years and doesn’t support newer React versions well. It also has known issues with touch scrolling and accessibility.

// ❌ Avoid in new projects
import { Scrollbars } from 'react-custom-scrollbars';

<Scrollbars>
  <div>Content</div>
</Scrollbars>

While its API was flexible, the lack of maintenance makes it a liability. Use rc-scrollbars as a drop-in successor if migrating.

react-perfect-scrollbar: Wrapper Around a Non-React Library

react-perfect-scrollbar is a React wrapper for the standalone Perfect Scrollbar library. It provides highly customizable scrollbars that mimic native inertia and support advanced features like wheel propagation and RTL.

import PerfectScrollbar from 'react-perfect-scrollbar';
import 'react-perfect-scrollbar/dist/css/styles.css';

function App() {
  return (
    <PerfectScrollbar options={{ wheelPropagation: false }}>
      <div>Long content...</div>
    </PerfectScrollbar>
  );
}

However, because it relies on direct DOM manipulation and MutationObserver to detect content changes, it can be slower and less predictable in complex React trees. You must also manage CSS imports manually.

🧭 Programmatic Scrolling: Smooth Navigation Without Styling

Unlike the above, react-scroll doesn’t touch scrollbar appearance. Instead, it gives you tools to scroll smoothly to elements—ideal for single-page apps with anchor navigation.

import { Link, Element } from 'react-scroll';

function App() {
  return (
    <div>
      <Link to="section1" spy={true} smooth={true} offset={-50}>
        Go to Section 1
      </Link>
      
      <Element name="section1">
        <h2>Section 1</h2>
        <p>Content here...</p>
      </Element>
    </div>
  );
}

It also provides a scroller object for imperative control:

import { scroller } from 'react-scroll';

scroller.scrollTo('section2', {
  duration: 800,
  delay: 0,
  smooth: 'easeInOutQuart'
});

Use this when you need smooth in-page navigation but don’t care about scrollbar styling.

📏 Measuring Scrollbar Width: Layout Stability

react-scrollbar-size solves a subtle but critical layout problem: the scrollbar’s width varies by OS and browser (e.g., 17px on Windows Chrome, 0px on macOS with auto-hiding). This can cause unwanted layout shifts when content overflows.

The package provides a hook to read the current scrollbar width:

import { useScrollbarWidth } from 'react-scrollbar-size';

function App() {
  const scrollbarWidth = useScrollbarWidth();
  
  return (
    <div style={{ paddingRight: scrollbarWidth }}>
      Content that might trigger scrollbars
    </div>
  );
}

This is especially useful in modals, fixed headers, or grid layouts where precise alignment matters. Note: it doesn’t render anything—it’s purely a measurement utility.

⚖️ Key Trade-Offs Summarized

💡 When to Combine Packages

In practice, you might use more than one:

• Use rc-scrollbars for custom scroll containers and react-scrollbar-size to adjust padding when native scrollbars appear elsewhere.
• Use react-scroll for navigation alongside rc-scrollbars in a sidebar that needs custom styling.

But avoid combining multiple custom scrollbar libraries—they can conflict on the same DOM node.

🛑 Final Recommendations

• For new projects needing custom scrollbars: Start with rc-scrollbars. It’s lightweight, React-native, and actively maintained.
• Avoid react-custom-scrollbars entirely—it’s deprecated and unsafe for production.
• Use react-perfect-scrollbar only if you need its specific visual fidelity and are willing to manage its external dependency and performance quirks.
• Reach for react-scroll when implementing smooth anchor navigation, not for styling.
• Add react-scrollbar-size only if layout shifts from scrollbar appearance are causing real UX issues—don’t over-engineer.

Each tool has its lane. Pick the one that matches your actual problem—not just the one with the most stars.
