Ping, Jitter and Packet Loss Explained

Download speed gets all the attention, but for gaming, video calls and livestreaming, these three numbers matter more.

Ping (latency)

Ping is the time a small signal takes to travel from your device to the server and back, measured in milliseconds (ms). Lower is better. Distance is the biggest factor: a server in your own country might answer in 5–30 ms, while a server on another continent can take 150–300 ms no matter how fast your package is.

Jitter

Jitter is how much your ping varies. A steady 40 ms ping feels smooth; a ping jumping between 20 ms and 120 ms causes stutter in games and robotic voices in calls, even if the average looks fine.

Packet loss

Packet loss is the percentage of data that never arrives and must be sent again. Any consistent loss above 1–2% will cause visible problems: freezing video, lag spikes and dropped call audio.

Use	Ping	Jitter	Packet loss
Competitive gaming	Under 50 ms	Under 10 ms	0%
Casual gaming & calls	Under 100 ms	Under 30 ms	Under 1%
Streaming & browsing	Under 200 ms	Not critical	Under 2%

How to fix a high ping

Use a cable or move closer to the router. Wi-Fi is the most common cause of ping spikes at home.
Use the 5 GHz Wi-Fi band if your router offers it — it is usually less crowded than 2.4 GHz.
Stop background uploads. Cloud backups and file sharing saturate your upload and push ping up sharply (this is called bufferbloat).
Choose nearby servers in games. No setting can beat geography — always pick the closest region.
If ping is high on cable too, at all hours, the issue is likely your provider's routing. Send them test results from different times of day.
