Network jitter—the variation in packet delay—is critical for VoIP calls, video conferencing, online gaming, and live streaming. High jitter causes choppy audio, frozen video, and laggy gameplay. This calculator analyzes your ping measurements to determine jitter quality and application suitability.
Jitter is the inconsistency in packet arrival times. When packets arrive at irregular intervals, real-time applications struggle to maintain smooth playback. Mean jitter measures the average variation between consecutive packets, while standard deviation shows overall consistency. The RFC 3550 formula provides the standard interarrival jitter used in RTP streaming.
Mean Jitter Formula
J = (1/(n-1)) × Σ|d(i+1) - d(i)|Jitter above 30ms causes audio distortion, choppy speech, and dropped syllables in voice calls.
High jitter causes rubber-banding, hit registration issues, and unpredictable lag spikes in online games.
Video streaming buffers and re-buffers more frequently when jitter is high, disrupting viewer experience.
Identifying jitter problems helps pinpoint network congestion, bad hardware, or routing issues.
Test your connection before important video calls to ensure jitter won't cause quality issues.
Document network jitter when reporting connection problems to your internet service provider.
Compare jitter to different game servers to find the most stable connection.
Quantify jitter problems to support business cases for network infrastructure improvements.
Latency is the time for a packet to travel from source to destination (measured in ms). Jitter is the variation in latency between packets. You can have low latency with high jitter (inconsistent but fast) or high latency with low jitter (consistent but slow). For real-time applications, both matter.
