A test uses up to about 450 MB on very fast connections. Server: Cloudflare
How to test your internet speed
- Close downloads, streams and other apps that use the internet, for the most accurate result.
- Press Start test and wait about 20 seconds while ping, download and upload are measured.
- Compare the results with your plan. Test a few times, and on both Wi-Fi and a cable if you can, to see where a slowdown comes from.
What the results mean
- Download: how fast you receive data. It matters for streaming, browsing and downloading files.
- Upload: how fast you send data. It matters for video calls, sending large files and cloud backups.
- Ping: the delay before data starts moving. Lower is better for gaming and calls.
- Jitter: how steady the ping is. Under 30 ms is good for calls.
A speed test without ads
Popular speed test sites fill the page with ads and trackers, which can even slow down the test. This one is a single clean page: no ads, no account and no app. It runs in your browser and measures against Cloudflare's global network.
Frequently asked questions
How does this speed test work?
It first sends a series of tiny requests to time the round trip (ping and jitter). It then downloads and uploads data over four connections at once for about eight seconds each and measures how fast it moves. The first moment of each transfer, while the connection speeds up, is left out.
Which server does it test against?
Cloudflare's public speed test network, which has data centers in hundreds of cities. You are connected to the nearest one automatically, and its code (for example LHR for London) is shown under the results.
What is a good internet speed?
For one person, 25 Mbps download is enough for 4K streaming and 3 Mbps upload for HD video calls. Households with several people streaming, gaming or working from home are better off with 100 Mbps or more. For games and calls, a ping under 50 ms and low jitter matter more than raw speed.
Why is my result lower than the speed my provider advertises?
Wi-Fi is the most common reason: distance, walls and other devices all slow it down. Other devices using the connection, a VPN, an old router or a busy evening hour can also lower the result. For the most accurate number, test on a cable connection with nothing else running.
How much data does a test use?
It depends on your speed. On a typical 50 Mbps connection a test uses roughly 60 MB. The test stops early after 300 MB of download and 150 MB of upload, so even on very fast connections it stays under about 450 MB. Keep that in mind on a limited mobile plan.
What are Mbps, ping and jitter?
Mbps (megabits per second) is how much data your connection can move each second. Ping is the time a tiny message takes to reach the server and come back, in milliseconds. Jitter is how much the ping varies from one message to the next. High jitter causes choppy calls and lag in games.
