Ready to test

Test if your internet is actually good enough

Run a quick browser-based diagnostic for calls, gaming, streaming, VPN, and remote work. Verdicts appear before raw technical numbers.

Measured from your browser to the nearest Cloudflare server with Cloudflare’s open-source speed test engine, so results reflect your connection to Cloudflare, not every site you use. Uses roughly 20–190 MB of data, more on faster connections, so use Wi-Fi if you are on a metered plan. Results are not sent back to Cloudflare. How we measure

Zoom and Teams meeting readiness

Video calls need stable upload, low jitter, and little lag under load. This page turns network metrics into a plain-English meeting readiness score.

Recommended targets

Upload above 3 Mbps for HD calls.
Latency below 50ms when possible.
Jitter below 10–15ms.
Packet loss below 1%.

Common call fixes

Use Ethernet for important meetings.
Pause cloud sync and uploads.
Turn off VPN if it increases latency.
Move closer to the router before the call.

Frequently asked questions

What internet speed do I need for Zoom?

For reliable HD Zoom calls, aim for at least 3 Mbps upload, 5 Mbps download, latency below 50ms, jitter below 10ms, and packet loss below 1%.

Is upload or download more important for Zoom?

Upload is often more important because your camera and screen share must be sent to other participants.

Why does Zoom freeze on fast internet?

Zoom can freeze when jitter or packet loss is high, even if download speed is strong.
