Top 7 WebRTC Video Quality Metrics and KPIs

The metrics that actually tell you if your video is good enough. And the ones that don't.

Your users don't file bug reports about video quality. They just leave. The gap between "it works" and "it works well" is where retention lives - and most teams aren't measuring the right things.

This guide breaks down the 7 metrics that matter most for production WebRTC video, explains what each one actually tells you, and shows you how to set thresholds that mean something for your use case.

What's inside

7 metrics. Each one explained with what it measures, why it matters, and when to act.

  • The difference between quality metrics you can control and the ones you can only observe
  • Why bitrate alone tells you almost nothing about actual video quality
  • The one metric that correlates most with user complaints - it's not what you'd expect
  • How to set thresholds that mean something for your specific use case
  • Resolution, frame rate, and the tradeoff your SFU is making without telling you
  • Jitter buffer behavior and what it reveals about your network path
  • A practical framework for turning raw getStats() numbers into action items

Who it's for

For teams that need to measure quality, not guess at it.

WebRTC developers

Building or maintaining a video application. You need to know which numbers to watch - and which ones are noise.

QA teams

Trying to define "good enough" video quality in measurable terms. This gives you the rubric.

Engineering managers

Who need to explain quality tradeoffs to product. This translates the numbers into business impact.
