Click to test your connection
We couldn’t complete the jitter test. Check your connection and try again.
Measured to our server in France (EU). This test times the round trip between your device and Pingvero’s test server in France. The farther you are from France, the higher the result will read, even on a healthy connection — a visitor in North America or Asia-Pacific will see a higher number than someone in Western Europe. Use it to compare your own connection over time rather than against someone far away.
Free online jitter test. No download or installation required. Results depend on the test server, your network route and conditions at the time of testing, and are not a guarantee of gaming, VoIP or streaming performance.
The Basics
What Is Jitter?
Jitter is the variation in how long each response takes, measured from one round trip to the next — not the response time itself.
On a stable connection, each round trip takes about the same time as the last; on an unstable one it swings around, even if the average looks fine. That swing is jitter — which is why a connection can have a low ping and still feel unpredictable.
| Sequence of round trips | What it means |
|---|---|
| 20 → 21 → 20 → 22 ms | Low jitter — steady and predictable, even though the ping itself is unremarkable. |
| 20 → 80 → 25 → 100 ms | High jitter — large swings between requests, which is felt as inconsistency. |
Reading Your Result
Is Your Jitter Good?
General guidelines, not fixed standards — what counts as fine depends on what you use the connection for.
Moderate jitter — 30–50 ms
Some Variation
Noticeable but not extreme swings between requests. May be fine for browsing, less so for sensitive real-time use.
High jitter — above 50 ms
Significant Variation
Response times swing widely. Calls, games and live streams are more likely to show the effects.
What “good” means also depends on the activity: online gaming and VoIP calls are the most sensitive to jitter, video calls and live streaming notice it somewhat less, and general browsing is largely unaffected. These ranges are general guidelines, not fixed standards — no single number guarantees a particular experience. The guide covers what jitter means for gaming and for video calls and VoIP in detail.

Jitter vs Ping vs Latency
Three different measurements of the same round trip.
| Term | What it measures |
|---|---|
| Jitter | The variation in latency from one round trip to the next. |
| Ping | The response time for a single round trip to a destination. See our Ping Test. |
| Latency | The time data takes to travel between two points on the network. See our Latency Test. |
Troubleshooting
Why Is My Jitter So High?
The usual suspects, in the order worth checking. A high result does not point to one specific cause.
- WiFi interference or a weak WiFi signal
- Congestion on your local network, or other devices using it
- An overloaded or outdated router
- Background downloads or uploads running during the test
- Congestion further along your ISP’s network
- A long or inconsistent route to the test server (see the note under the test)
Quickest first checks: test again over wired Ethernet, closer to the router, with nothing else downloading. If the result improves, WiFi or local congestion is the cause; if it does not, compare results at different times of day before contacting your ISP.
If your ping is high as well as unsteady, the causes overlap — see how to fix high ping. Curious about raw speed instead? Run the Internet Speed Test.
FAQ
Jitter Test FAQ
Short answers to the questions people ask most about testing and reducing jitter.
What is a jitter test?
A jitter test measures how much your network latency changes from one moment to the next. It sends a series of requests to a test server and looks at the variation between the response times, rather than a single ping value.
What is a good jitter?
As a general guideline, under 10 ms is excellent, 10–30 ms is good for most gaming and video calls, 30–50 ms is fair but noticeable, and above 50 ms is considered high. These are indicative ranges, not fixed standards, and needs vary by activity.
What does high jitter mean?
High jitter means your connection’s response time is swinging significantly between requests, even if the average looks fine. That instability is what tends to cause choppy calls, stuttering video and unpredictable lag in games.
How is jitter measured?
Jitter is calculated from a series of latency samples. This tool takes the average difference between consecutive measurements — a steady sequence produces a low number, a sequence that jumps around produces a high one.
Why is my jitter so high?
Common causes include WiFi interference, a weak wireless signal, network congestion, an overloaded router, other devices sharing the connection, or congestion further along your ISP’s network. It can also simply be a busy moment on the test route.
Is jitter important for gaming?
Yes. Online games are sensitive to timing, so a connection with low ping but high jitter can still feel inconsistent, with movements and hits that register late or out of order. Check your ping alongside jitter.
How can I reduce jitter?
Use a wired Ethernet connection where possible, move closer to your router, reduce WiFi interference, pause large downloads or uploads while testing, and restart your router. If jitter stays high across several tests, contact your ISP.
