The four numbers that matter

What your speed test measures

Every test reports four core metrics. Here's what each one tells you about your connection.

Download

How fast data reaches you - Streaming, browsing and loading pages. Learn more →

Upload

How fast you send data out - Calls, backups and posting. Learn more →

Ping

Round-trip delay in milliseconds - The key to gaming and calls. Learn more →

Jitter & loss

How steady the line is - The cause of stutter and dropouts. Learn more →

FAQ

Speed test questions, answered

Your browser downloads a stream of random data from our server and times how fast it arrives (download), then sends data back and times that (upload). It also pings the server repeatedly to measure round-trip delay (ping), how much that delay varies (jitter) and whether any pings go unanswered (packet loss). All timing happens on your device.
Wi-Fi, old routers, background downloads, VPNs, network congestion and the device itself can all reduce measured speed. For the most accurate result, connect by Ethernet cable, pause other downloads, and run the test two or three times. If you're still far below your plan, try these fixes.
For a single person, 25–50 Mbps is plenty. A busy household with 4K streaming and several devices is comfortable at 100–300 Mbps. Gamers and video callers should care more about a low ping than raw Mbps. See our speed requirements guide.
No. The test runs entirely in your browser and we don't save your results. Your IP address is looked up only to show your provider on this page and is never stored. See our privacy policy.
Test at different times of day - Especially during peak evening hours - To see how your connection holds up under congestion. Run it two or three times in a row and take the best result, since a single test can be affected by momentary Wi-Fi interference.
