More about Internet Speed Test – Check Download, Upload & PingHow to use, good to know & FAQ
What do ping, jitter and packet loss mean?
- Ping (latency): how long data takes to make a round trip, in milliseconds. Lower is better.
- Jitter: how much the ping jumps around between requests. High jitter causes choppy calls and rubber-banding in games.
- Packet loss: the share of requests that never came back. Anything above about 1–2% is noticeable.
What is a good ping?
- Under 50 ms: excellent for online gaming.
- 50–100 ms: good for video calls and most games.
- 100–150 ms: fine for browsing and streaming.
- Over 150 ms: games and calls will feel laggy.
How to test your internet speed and ping
- Close downloads and streams on your network for the most accurate result.
- Tap GO and wait about 5 seconds.
- Read your ping, jitter and packet loss, then tap Test again to compare (for example, Wi-Fi vs cable).
Good to know
- This is an HTTP ping from your browser to the nearest Cloudflare data centre, which is what most games and apps rely on. Browsers can’t send the ICMP pings the command line uses.
- Your last result is saved in your browser only, so you can compare before and after changes.
What do download and upload speed mean?
- Download speed: how fast data reaches you – what matters for streaming, browsing and downloading files. Measured in megabits per second (Mbps).
- Upload speed: how fast you can send data – what matters for video calls, uploading photos and live streaming.
- Ping, jitter and packet loss: how quick and stable your connection feels – what matters most for online games and calls.
How much internet speed do I need?
- Browsing and email: 5 Mbps or more.
- HD streaming on one screen: about 10–25 Mbps.
- 4K streaming: 25 Mbps or more per screen.
- Video calls: 3 Mbps or more upload.
- Online gaming: any stable speed above 10 Mbps, with ping under 60 ms.
Good to know
- The test uses the nearest Cloudflare server and runs entirely in your browser – nothing is installed.
- A full test uses some data (often 50–150 MB on fast connections), so keep that in mind on mobile data.
- For the most accurate result, pause downloads and streaming on your network first, or test on a cable instead of Wi-Fi.
Frequently asked questions
What is a good internet speed?
For most homes, 25–100 Mbps download is good. It lets several people stream HD video and join video calls at the same time. Gamers should also look for ping under 60 ms.
Why is my speed lower than my plan?
Wi-Fi distance, other devices using the connection, an old router or a busy network at peak hours can all lower your result. Test on a cable to see the real speed of your line.
How can I lower my ping?
Use a wired connection, move closer to the router, stop other downloads, restart your router, and pick game servers near you.
Why is my jitter high?
Usually Wi-Fi interference or a busy network. Try a cable or a 5 GHz Wi-Fi band.
Is ping the same as internet speed?
No. Speed is how much data you can move per second; ping is how fast a single round trip is. You can have fast speed and still have high ping.
What causes packet loss?
Weak Wi-Fi, faulty cables, an overloaded router or problems at your ISP. If it continues on a cable, contact your provider.
When to use it
Before a ranked game or an important video call, after changing your router or ISP, or when your connection feels laggy.
