How to Test Your Internet Speed (and What Mbps You Actually Need)

An internet speed test measures three separate things, and conflating them is why "my internet is slow" complaints don't always match what the test reports. Knowing what each number means makes the result actually useful for diagnosing a problem.

What a speed test measures

• Download speed (Mbps): how fast data comes to you — this is what determines streaming quality, page load speed, and download times.
• Upload speed (Mbps): how fast data goes from you to the internet — this matters for video calls, uploading files, and live streaming, and is often much lower than download speed on home connections.
• Ping (ms): the round-trip delay for a signal to reach a server and come back — low ping matters most for gaming and real-time video calls, where lag is more noticeable than raw throughput.

How to run a speed test

• Open the Speed Test tool.
• Run the test with no other heavy downloads or uploads happening on your network for an accurate reading.
• Check download, upload, and ping together — a full picture, not just one number.

Realistic Mbps targets

• HD video streaming: ~5-10 Mbps download per stream.
• 4K streaming: ~25 Mbps download per stream.
• Video calls: ~3-5 Mbps both download and upload for a smooth call.
• Online gaming: bandwidth needs are low (a few Mbps), but ping under ~50ms matters far more than raw speed.

If your results are consistently far below what your plan promises, test at a different time of day and on a wired connection if possible — that isolates whether the issue is your ISP, your WiFi, or network congestion at peak hours.
