Jitter Test

Jitter is the variation in latency between consecutive requests. Even a fast connection can feel bad in video calls or games if latency jumps around. This test takes 40 latency samples and calculates the average change between them.

Tool status: Functional with limitations Works, but there are technical limits explained on the page.

Jitter (latency variation)

40 samples, about 10 seconds.

Median–ms
Minimum–ms
Jitter–ms
Failed requests–%

Target: . Nothing is measured until you press Start.

What this tool can and cannot do

Measured with HTTPS requests to our server (browsers cannot send raw UDP or ICMP). Real-time apps like calls use UDP, so their jitter may differ slightly, but trends are comparable.

Data sources: IPandNet test server

Understanding the results

Jitter = average absolute difference between consecutive latency samples. Under 5 ms is excellent, 5–15 ms good, 15–30 ms may cause occasional call glitches, above 30 ms is poor.

Troubleshooting

  • Use a wired connection, stop large uploads/downloads on other devices, and enable QoS/SQM on your router if available.

Frequently asked questions

Is jitter more important than speed?

For calls and games, yes. Real-time applications need consistent timing; they only use a few Mbps of bandwidth.
