Jitter Guide

What is good jitter in a speed test?

Good jitter means your latency stays consistent instead of jumping up and down. As a simple rule, below 10 ms is good for most real-time uses, 10 to 20 ms is often usable, and anything above 20 to 30 ms is worth investigating.

Quick answer: good jitter ranges

Jitter result How to read it Best fit
Below 5 ms Excellent stability with very little latency variation. Gaming, calls, voice chat, live meetings
5 to 10 ms Good for most real-time internet activity. Most homes, work calls, streaming, casual gaming
10 to 20 ms Usually usable, but spikes may become noticeable. Browsing, streaming, less sensitive games
20 to 30 ms Unstable enough to affect calls, games, or live voice. Needs troubleshooting for real-time apps
Above 30 ms Poor stability for anything that depends on steady timing. Check Wi-Fi, congestion, routing, or packet loss

Jitter should be read together with ping and packet loss. A low average ping can still feel bad if jitter is high, because the connection is not responding at a steady pace.

Good jitter depends on what you are doing

  • Gaming feels best when jitter stays below 10 ms because response timing is more consistent.
  • Video calls can often tolerate a little more jitter, but voice can stutter when spikes get frequent.
  • Streaming usually buffers ahead, so it is less sensitive unless packet loss or Wi-Fi drops are also present.
  • Browsing is the least sensitive, but high jitter can still make pages feel uneven or slow to respond.

What to check when jitter is high

  • Run several tests instead of trusting one result.
  • Compare Wi-Fi with mobile data or Ethernet when possible.
  • Pause downloads, cloud backups, app updates, and 4K streaming on the same network.
  • Move closer to the router and test again to check signal quality.
  • Look at packet loss too, because dropped packets often make jitter feel worse.

Is your jitter good enough?

For gaming

Aim for below 10 ms. If the game rubber-bands or aim feels uneven, compare jitter with ping and packet loss.

For video calls

Below 10 ms is smooth, while 10 to 20 ms is often usable. Spikes above that can create voice gaps.

For everyday use

Browsing and buffered video are more forgiving, but high jitter still points to Wi-Fi interference or congestion.

Measure jitter with the rest of the network picture

LizSpeedTest helps you check jitter together with ping, packet loss, download speed, and upload speed so you can understand whether a bad experience comes from delay, instability, dropped packets, or raw bandwidth.
