Ping & Jitter Test

Measure how quickly your connection responds and how steady it is. These two numbers decide how smooth gaming and video calls feel.

Press Start to take 30 quick measurements and see how each one performs.

How it is measured: the test times small HTTPS requests to Cloudflare's nearest server and subtracts the time the server takes to answer, so the result is the round trip over your connection. The first request is discarded as a warm-up, ping is the median of 30 samples and jitter is the average difference between consecutive samples. Results show the path to Cloudflare, which can differ from the path to your game or call server. True packet loss needs a different, UDP-based measurement that this test does not run, so sudden spikes and failed samples are the signs to watch here. Nothing is stored.

How to lower ping and jitter

  • Use an Ethernet cable instead of Wi-Fi, or move closer to your router.
  • Pause downloads, uploads and streaming on other devices while you test.
  • Restart your router and modem, then test again.
  • Turn off your VPN, or compare the result with and without it.
  • Test at different times of day. Busy evening hours often raise ping and jitter.

Common questions

What is Ping?
Ping is the time it takes for a data packet to travel from your device to a server and back. It's measured in milliseconds (ms) and indicates the responsiveness of your connection. A lower ping means a faster, more responsive connection, which is crucial for online gaming, video calls, and other real-time applications.
What is Jitter?
Jitter is the variation in the time it takes for data packets to travel from your device to a server and back. It reflects how consistently data is transmitted across your connection. High jitter can lead to disruptions in real-time applications like online gaming, video streaming, and VoIP, causing delays, lag, or poor-quality communication.
How does a ping & Jitter test work?
A ping & jitter test sends small data packets from your device to a server and measures how long it takes to get a response (ping) and the consistency of the response times (jitter). Using the Cloudflare API, these tests are run on fast, reliable servers, ensuring accurate results. The test helps identify latency and connection stability issues that can affect real-time applications like gaming, streaming, and VoIP.
What is a good Ping value?
A good ping is generally under 50ms. Anything between 50ms and 100ms is acceptable for most activities, while pings over 100ms may cause noticeable delays.
What is a good Jitter value?
A good jitter value is typically less than 20ms. High jitter (above 30ms) can cause lag, stuttering, or interruptions in activities like video calls or online gaming.
How can I reduce high Ping or Jitter?
You can reduce high ping or jitter by using a wired connection, minimizing network traffic, restarting your router, or switching to a server closer to your location.
Can a Ping & Jitter test improve my internet connection?
While a ping & jitter test itself won't improve your connection, it can help you diagnose issues and guide you on what changes to make for better performance.
