How to use the speed test
- Close any large downloads or streams that are using your connection.
- Press "Start test".
- Wait a few seconds while the tool downloads a fixed amount of data.
- Read your download speed in Mbps, along with the amount of data transferred and the time it took.
What this test measures
This tool measures download throughput — how fast data travels from this server to your device. When you press start, your browser downloads a fixed amount of data and the page times exactly how long it takes. Dividing the amount of data by the elapsed time gives a speed in megabits per second, the same unit your internet provider quotes on your plan.
Importantly, the result reflects the path between you and this specific server, not your connection's absolute maximum. It is a single direction of traffic (download only), so it does not include upload speed.
Why your result can vary
Several factors move the number up and down between runs. Distance and routing to the server are a big one — a far-away server gives a lower result even on a fast line. Wi-Fi signal, other devices sharing your network, and background activity like updates or streaming all reduce the measured speed. Running the test several times and taking the best result gives the most accurate picture.
How to get an accurate reading
- Run the test on a wired connection rather than Wi-Fi when you can.
- Pause streaming, downloads and cloud backups during the test.
- Test at different times of day to see how peak-hour congestion affects you.
- Repeat the test a few times and compare the results.
Mbps versus megabytes per second
Speed tests report in megabits per second, while file downloads in your browser show megabytes per second. Because one byte is eight bits, divide the Mbps figure by eight to compare the two. A 100 Mbps result means files download at roughly 12.5 megabytes per second in ideal conditions. Keeping the units straight avoids thinking your connection is underperforming when it is simply being measured differently. This tool follows the same convention your provider uses, so the result is directly comparable to the plan you pay for.
