Efficient List Rendering: Infinite Scroll vs. Pagination

Have you ever scrolled through a product catalog or a social feed that felt painfully slow? That lag usually happens when too much data is rendered all at once. In real-world frontend systems, where performance and user experience matter most, loading everything upfront doesn’t scale. That’s where smart list rendering comes in. We keep interfaces fast and fluid by breaking data into manageable chunks using techniques like pagination or infinite scrolling. In this lesson, we’ll look at ways to load lists faster, explore smart rendering techniques, and compare the two well-known techniques—infinite scroll vs. pagination.

Large list rendering

Large list rendering refers to efficiently displaying and managing extensive datasets in a web application, ideally—without compromising performance. When not optimized, rendering large lists can lead to slow interactions, high memory consumption, and excessive rerender, negatively affecting the user experience.

Pagination and infinite scrolling are commonly used to dynamically load and manage content to address these challenges.

Let’s start with pagination.

What is pagination?

Pagination is a traditional method for handling large datasets by dividing content into separate pages, making data retrieval more efficient and improving user experience. In web and application development, pagination is commonly used to display lists of items such as search results, user comments, or product catalogs. It helps prevent overwhelming the user with excessive data at once and reduces performance bottlenecks. To better understand how pagination works, let’s explore the different types of pagination techniques commonly used.

Types of pagination

Depending on the use case, different pagination techniques offer varying levels of efficiency. The three primary types of pagination are:

Page-based pagination: This method divides data into fixed pages, allowing users to navigate using numbered links or next/previous ...
