Ping, jitter and packet loss explained
What is ping?
Ping (or latency) is the round-trip time for a small packet to travel from your device to a server and back, measured in milliseconds. Lower is better. It's the single biggest factor in how responsive your connection feels — distinct from bandwidth, which is how much data you can move at once. A fast download speed with high ping still feels laggy in calls and games.
What is jitter?
Jitter is how much your ping varies between probes. A steady 40 ms is far better than a connection that bounces between 20 and 120 ms, even if the average is the same — variable latency is what causes audio to break up and game characters to "teleport." We measure it as the average change between consecutive round-trips.
What is packet loss?
Packet loss is the share of probes that never came back. Any sustained loss above zero is worth investigating — it forces data to be resent and shows up as stutter, dropped calls and rubber-banding. Here, a probe that times out counts as one lost packet.
What's a good ping?
- Under 20 ms: excellent — competitive gaming and crisp video calls.
- 20–50 ms: good — smooth for almost everything.
- 50–100 ms: fair — fine for browsing and streaming, some lag in fast games.
- Over 100 ms: high — interactive apps start to feel sluggish.
Results vary with Wi-Fi interference, distance to the server, and other devices on your network — run the test a few times for a representative picture.
