What the jitter value means
A low value means consecutive response times stayed close together. The displayed range shows the distance between the fastest and slowest raw samples.

HTTP edge jitter — not ICMP. Jitter is calculated from consecutive unloaded Cloudflare edge-latency samples; browser, Wi-Fi, VPN and routing conditions can influence the result.

RESULT / EXPLAINED
Consistency matters even when average latency looks fine.
Jitter describes variation between unloaded Cloudflare edge-latency samples. Lower variation generally produces smoother real-time interaction.
Practical bands
Up to about 5 ms is excellent, 5–10 ms is generally good, 10–20 ms deserves attention and sustained values above 20 ms can disrupt sensitive real-time traffic.
One route, one sample
This is HTTP edge jitter, not universal packet timing. Browser scheduling, Wi-Fi contention, VPNs and transient routing changes can all influence the sample.
Confirm instability
Repeat the test several times. If jitter stays high, compare a wired connection and check whether uploads, cloud sync or other devices are saturating the network.
0BPS SHOWS MEASURED OR CALCULATED FACTS SEPARATELY FROM INTERPRETATION. WHERE A RESULT IS ADVISORY, ESTIMATED OR DESTINATION-SPECIFIC, THE LIMIT IS STATED IN THE TOOL.
REFERENCE / FAQ
COMMON QUESTIONS
What is network jitter?
Jitter is variation between repeated latency measurements. A connection can have a good average ping but still feel unstable when latency changes sharply from one sample to another.
Is lower jitter better?
Yes. Consistent timing is especially useful for real-time traffic such as gaming, voice chat and video calls.
Jitter is the average change between consecutive unloaded Cloudflare edge-latency samples. Lower variation is usually better for real-time traffic.
This browser test reflects HTTP edge timing rather than native router-level ICMP measurements.
PRACTICAL / EXAMPLES
PUT THE NUMBER IN CONTEXT.
Short examples using the same units and assumptions as this module.
Samples around 18, 19, 18 and 20 ms have low variation.
Samples that jump between 20 and 100+ ms can disrupt voice, games and calls even if the average looks acceptable.
