Internet speed test: what it is for
The test measures the ping and its variation (jitter), then downloads and uploads test files to the nearest server on the Cloudflare network, showing the download and upload speed in Mbps on a speedometer and a live chart.
At the end, the tool shows what your connection can handle, such as HD or 4K video, video calls, online games and homes with several screens. The test data is discarded.

Frequently asked questions
Why is the speed lower than my plan?
Wi-Fi loses a lot of speed with distance and walls, other devices may be using the network and your phone or computer may be limiting it. To check your plan, test with the computer plugged straight into the router by cable.
How much internet do I need?
For HD video, about 5 Mbps per screen; for 4K, 25 Mbps. Video calls use 2 to 4 Mbps of upload. For online games, ping matters more than speed: under 50 ms is good and under 20 ms is great.
Which server does the test use?
The test files come from the Cloudflare network, from the point of presence closest to you. The test data is discarded: nothing is stored.
