Pagination vs Virtual Scrolling:
when to use each

Learn when to use pagination and when to use virtual scrolling in JavaScript data grids, dashboards and enterprise web applications.

Pagination and virtual scrolling are two different ways to handle large datasets in a web application. Both can improve performance, but they create very different user experiences.

Pagination divides data into separate pages. Users see a limited number of records, such as 25, 50 or 100 rows, and move between pages using navigation controls. This approach is simple, familiar and works well for search results, public listings, admin tables and situations where users do not need to scan a continuous dataset.

Virtual scrolling creates the feeling of one continuous list or grid. Instead of loading a new page, users scroll through the dataset. The grid renders only the visible rows and updates them as the user moves. This approach is useful when users need to explore, compare or edit many records without interruption.

Use pagination when the user’s workflow is page-based or search-based. For example, an ecommerce admin panel showing orders may work well with pagination if users usually search by customer, order number or date range. Pagination can also be easier for SEO pages, public listings and simple backend-driven tables.

Use virtual scrolling when users need speed and continuity. Financial data, logs, inventory, analytics tables, operational dashboards and large internal tools often benefit from virtual scrolling because users can move through large datasets without clicking through pages. It also feels closer to a desktop application or spreadsheet.

There are trade-offs. Pagination is simple and predictable, but it can interrupt workflows. Virtual scrolling is smoother, but it requires stronger technical implementation. The grid must preserve scroll position, selection, editing state, keyboard navigation and loading behavior.

The right choice depends on the user task. If users search, open one record and leave, pagination may be enough. If users scan, compare, edit or analyze many rows, virtual scrolling is usually better.

For high-performance JavaScript data grids such as FastGrid, virtual scrolling is a key feature because it allows large datasets to be handled directly in the browser without forcing users into page-by-page navigation.
