The four key measurements
Every speed test reports four numbers. Download and upload speeds (in Mbps) describe how fast data moves to and from your device. Ping (in ms) is how responsive your connection is, and jitter (in ms) measures how stable that responsiveness is over time.
How much speed do I need?
| Speed | Good for |
|---|---|
| 1–10 Mbps | Basic browsing, email, SD video on one device. |
| 10–50 Mbps | HD streaming, video calls, a few connected devices. |
| 50–200 Mbps | 4K streaming, gaming, busy households, remote work. |
| 200 Mbps+ | Heavy 4K/8K streaming, large downloads, many users at once. |
Tips for accurate results
- Test over a wired Ethernet connection where possible to remove Wi-Fi variability.
- Close background apps and downloads before testing.
- Run the test a few times and take the average.
- Test at different times of day — networks are often slower at peak evening hours.
Frequently asked questions
How accurate is a browser-based speed test?
Browser tests are a reliable estimate of real-world performance. Results can vary with Wi-Fi signal, device capability, browser overhead, and network congestion, so run a few tests for a representative average.
How often should I test my internet speed?
Test when you notice problems, after changing equipment or plans, or to compare different times of day. Testing at a wired connection close to your router gives the cleanest baseline.
Why do results differ between tests?
Network conditions change constantly — congestion, background app usage, and Wi-Fi interference all play a part. Averaging several tests gives the most realistic picture.
