3D on the Web Without Killing Performance
3D makes brands feel premium — until it makes the page slow. A performance budget for web 3D.
Interactive 3D can make a brand unforgettable. It can also add megabytes of JavaScript and models that ruin load times on mobile. The difference is a performance budget decided before production starts.
Set a budget
- Keep the 3D library out of the initial bundle — load it after the page is interactive.
- Aim for models of a few hundred kilobytes, compressed with Draco or Meshopt.
- Prefer procedural geometry and baked lighting over heavy textures.
- Cap the device pixel ratio so high-density screens don't render four times the pixels.
Render only when visible
Pause rendering when the canvas is off-screen or the tab is hidden. A scene that keeps rendering in the background drains batteries and slows everything else.
Always have a fallback
Users on low-power devices, with WebGL disabled or who prefer reduced motion should see a clean static visual — and the page's content should never depend on the 3D loading at all.
Design for the story
The best web 3D supports a message: a product revealing its details, a process assembling itself, a network connecting markets. Decoration for its own sake rarely justifies the cost.
