What the numbers mean
- Download
- How fast stuff gets to you: streaming, loading websites, downloading games and apps. Good: 25 Mbps handles a 4K stream. 100 Mbps or more is comfortable for a busy household.
- Upload
- How fast stuff leaves your device: video calls, posting videos, cloud backups. Good: 10 Mbps is plenty for video calls. More helps if you send big files.
- Ping
- How long your connection takes to respond, in milliseconds (ms). It’s why a game feels snappy or laggy. Lower is better. Good: Under 30 ms is great for gaming. Under 100 ms is fine for calls and browsing.
- Jitter
- How much your ping bounces around. Even with a good ping, lots of jitter makes calls choppy and games feel uneven. Lower is better. Good: Under 10 ms is very steady. Under 30 ms is fine for video calls.
- Mbps
- Megabits per second, the usual unit for internet speed. Internet plans are sold in Mbps too, so you can compare your result to your plan.
How this test works
We download and upload test files to Cloudflare, starting small and going bigger until the reading settles. Ping and jitter are measured along the way.
Your result can come in under the speed on your bill. Wi-Fi, an older device, or other people using the connection all eat into it. For the truest number, test on a cable with nothing else running. On a fast connection the test can use a few hundred MB of data.
