Internet Speed Test

More than a headline speed

A fast connection can still feel slow when latency jumps under load. This test measures throughput in both directions, idle ping, jitter, and responsiveness while downloading. It then translates those numbers into practical guidance for streaming, video calls, gaming, and cloud work.

How the measurement works

Your browser downloads and uploads temporary blocks of data to Cloudflare's nearby edge network. The transfer size and elapsed time produce an estimate in megabits per second. Several small requests estimate round-trip latency and variation. Results can change with Wi-Fi signal, VPNs, browser load, congestion, device power saving, and the chosen test server.

Getting a reliable result

• Pause large downloads, cloud backups, and streaming on other devices.
• Run two or three tests at different times instead of relying on one result.
• Compare Wi-Fi with Ethernet when diagnosing a home connection.
• Disable a VPN temporarily only if your policy allows it; then test both ways.
• Use Lite mode on cellular data. Deep mode is best for fast fixed connections.

Interpreting the ratings

Streaming ratings use approximate bandwidth tiers, while video-call and gaming ratings also weigh latency and jitter. These are practical estimates, not guarantees: service compression, distance to a game server, household usage, and provider routing can all change real-world performance.
