Speed Test
Test your internet speed – measure download, upload and ping for free.
The speed test measures the connection speed between your browser and our server. Results may vary depending on network load.
Average Speeds by Country
How the Speed Test Works
Our speed test measures in three phases: First, the ping (latency) is determined through 12 consecutive requests. Then download speed is measured over 8 seconds with adaptive data chunks – smaller packets for slow connections, larger ones for fast ones. Finally, upload is measured over 6 seconds. Results are stored anonymously (country code only) to enable average comparisons by country.
Tips for Accurate Results
- Use a wired (LAN) connection instead of Wi-Fi for the most accurate measurement.
- Close other tabs, downloads and streaming services during the test.
- Run the test at different times of day – the network is often congested in the evening.
- Restart your router if results are significantly below your plan speed.
- Test multiple times and compare results for a reliable picture.
Frequently Asked Questions about Speed Test
How accurate is a browser speed test?
A browser speed test provides a good reference value, but can be influenced by browser overhead, Wi-Fi quality and other running applications. For the most accurate measurement, use a cable (LAN), close other programs and run multiple tests.
Why is my internet slower than stated in my contract?
The contractually agreed speed is a maximum ("up to"). Factors such as network load (evening peak times), Wi-Fi quality, distance to the router, outdated network hardware or server bottlenecks can reduce the actual speed.
What are good download and upload values?
For normal browsing, 25 Mbps is sufficient. For HD streaming at least 50 Mbps is recommended, for 4K streaming 100 Mbps. Home office with video conferencing requires approximately 50 Mbps download and 10 Mbps upload. Gaming primarily requires a low ping (under 30 ms).
