Download speed
How fast data reaches you, in megabits per second (Mbps). It decides how quickly pages load, videos start and files download. Most of what you do online is download.

What your results mean
Upload speed
How fast you can send data: video calls, uploading photos and videos, cloud backups and live streaming. Many plans have a much lower upload than download speed.
Ping (latency)
The time a small message takes to reach the server and come back, in milliseconds (ms). Lower is better: under 30 ms feels instant, over 100 ms you notice delays in games and calls.
Jitter
How much the ping changes from one moment to the next. High jitter makes voice and video calls break up and games feel uneven, even when the average ping is fine.
Latency under load (bufferbloat)
Your ping while the connection is busy downloading or uploading. If it jumps far above the idle ping, calls and games lag whenever someone else in the home streams or downloads. A router with SQM or Smart Queue fixes it.
What is a good internet speed?
Speeds per device for a smooth experience. Add them up for everyone online at the same time.
| Activity | Download | Upload | Ping |
|---|---|---|---|
| Browsing, email, social media | 5 Mbps | 1 Mbps | < 100 ms |
| HD video streaming | 10 Mbps | 1 Mbps | any |
| 4K video streaming | 25 Mbps | 1 Mbps | any |
| Video calls (HD) | 10 Mbps | 5 Mbps | < 100 ms |
| Online gaming | 15 Mbps | 5 Mbps | < 50 ms |
| Home with 4+ people working and streaming | 200 Mbps | 30 Mbps | < 50 ms |
How to get faster internet
- Restart your router and modem. It clears memory and often fixes a sudden slowdown.
- Put the router in an open, central spot, raised up and away from walls, metal and the microwave.
- Use the 5 GHz or 6 GHz Wi-Fi band near the router; 2.4 GHz reaches further but is slower and more crowded.
- Test with a cable. If wired is much faster than Wi-Fi, the problem is coverage, not your plan; a mesh system or access point helps.
- Pause large downloads, cloud backups and updates on other devices while you game or call.
- Turn on SQM or Smart Queue in the router settings to stop lag under load.
- Update the router firmware, and replace routers older than about five years.
- If speeds stay well below your plan on a cable, contact your provider with your test results.
How this speed test works
The test runs in your browser against the nearest data center of Cloudflare's global network, so the server is close to you and results are consistent.
Ping is measured from many small requests, with the server's processing time removed, so you see the real network round trip. Jitter is how much those pings vary.
Download and upload are measured with transfers of growing size until your connection is saturated. Ping is also measured during the transfers to show latency under load.
A test on a very fast connection can use a few hundred MB of data. Results are saved only in your browser; this site uses no cookies and no tracking.

Frequently asked questions
Is this internet speed test free?
Yes. The test is completely free, needs no account, and works in any modern browser on phones, tablets and computers.
Why is my speed lower than my internet plan?
Plans are sold as a maximum. Wi-Fi distance and walls, older devices, other people using the connection and busy evening hours all lower what you get. Test with a cable next to the router to see what your line delivers.
Why is Wi-Fi slower than a wired connection?
Wi-Fi loses speed with distance, walls and interference from neighboring networks. The 5 GHz and 6 GHz bands are faster near the router, and a mesh system helps in large homes.
What is a good ping for gaming?
Under 30 ms is excellent and under 50 ms is good for fast games. Also check latency under load: if it rises a lot during the test, games will lag when others use the internet.
What is jitter and why does it matter?
Jitter is the variation in ping. Under 10 ms is good. High jitter makes calls robotic and games stutter, even if your speed is high.
What is bufferbloat?
Bufferbloat is extra delay when the connection is busy, because the router queues too much data. The test shows it as latency under load. Enabling SQM or Smart Queue on the router usually fixes it.
How much data does a speed test use?
It depends on your speed: a few MB on slow connections and up to a few hundred MB on very fast fiber or 5G. Keep that in mind on a limited mobile plan.
Does the test work on 4G and 5G mobile data?
Yes. It measures whatever connection your device is using: Wi-Fi, mobile data (3G, 4G, 5G), fiber or cable.
