Internet Speed Test
Check your download speed, upload speed, ping and jitter in about 20 seconds. No sign-up and no installation needed.
How to use the internet speed test
Our speed test measures how quickly data moves between your device and a test server. For the most accurate result, follow these steps:
- Close apps and browser tabs that use the internet, such as video streams, game updates and cloud backups.
- If you can, connect with a network cable, or stand close to your Wi-Fi router.
- Press the Start button and wait about 20 seconds without using the connection.
- Read your ping, jitter, download and upload results. Run the test two or three times, at different times of day, to see your typical speed.
What your speed test results mean
- Download speed is how fast data comes to your device. It matters for streaming, browsing and downloading files.
- Upload speed is how fast data leaves your device. It matters for video calls, cloud backups and sending large files.
- Ping (latency) is the time a signal takes to reach a server and return. Lower is better, especially for gaming and calls.
- Jitter is how much your ping changes from one moment to the next. High jitter causes choppy calls and lag.
How much internet speed do you need?
These are general guidelines. If several people or devices use the connection at the same time, add their needs together.
| Activity | Suggested speed | Ping |
|---|---|---|
| Web browsing and email | 3 - 5 Mbps | Any |
| HD video streaming (per stream) | 5 - 10 Mbps | Any |
| 4K video streaming (per stream) | 15 - 25 Mbps | Any |
| Video calls | 3 - 8 Mbps download and upload | Under 100 ms |
| Online gaming | 10 - 25 Mbps | Under 50 ms |
| Large downloads and cloud backup | 50 Mbps or more | Any |
How to improve a slow internet connection
- Restart your router. Turn it off for 30 seconds, then turn it on again.
- Move closer to the router or place it in a central, open spot. Walls and metal objects weaken Wi-Fi.
- Use a cable for computers, consoles and TVs. A wired connection is more stable than Wi-Fi.
- Disconnect devices you do not use and pause large downloads and updates.
- Try the 5 GHz Wi-Fi band if your router supports it. It is usually faster at short range.
- Contact your provider if the speed is always far below your plan, even with a cable and no other devices.
About this speed test
The test runs in your browser and works on phones, tablets and computers. First it measures ping with a series of short requests and calculates jitter from the differences between them. Then it downloads data from a test server over several connections at once, and finally it uploads data. The first second of each phase is ignored, so the short start-up period of a connection does not lower your result.
Different speed tests can show different numbers, because each one uses its own servers and method. Use the result as a reliable estimate of your connection, and compare tests made under the same conditions.
Frequently asked questions
How does this internet speed test work?
Your browser downloads and uploads test data for a few seconds and measures how fast it moves, then calculates your speed in Mbps. Ping and jitter come from many short requests to a test server. The whole test takes about 20 seconds.
Why is my result different from my ISP plan?
Wi-Fi quality, other devices on your network, the distance to the test server and network congestion all change the result. Internet providers also advertise maximum speeds, which you may not always reach. For the most accurate test, use a cable connection and close other apps.
What is a good internet speed?
About 25 Mbps is enough for HD streaming and everyday browsing for one or two people. Households with several users, 4K video or online gaming do better with 100 Mbps or more and a ping under 50 ms.
What is the difference between Mbps and MB/s?
Mbps means megabits per second and is how internet plans and speed tests are measured. MB/s means megabytes per second and is what most download managers show. One byte has 8 bits, so 100 Mbps is about 12.5 MB/s.
Why is my upload speed slower than my download speed?
Most home connections are built with more download capacity than upload capacity, because people mostly download content. Upload speed matters more for video calls, live streaming and backing up files to the cloud.
What are ping and jitter?
Ping is the time, in milliseconds, for a small signal to travel to a server and back. Jitter is how much that time changes between measurements. Low ping and low jitter mean a smooth experience in games and video calls.
Does the speed test use a lot of data?
Yes. The test sends and receives data at full speed for several seconds, so a full run can use from a few dozen to several hundred megabytes, depending on how fast your connection is. Avoid running it often on a limited mobile data plan.
Do you store my speed test results?
The test uses random data that is thrown away after it is measured. Read our Privacy Policy for full details on how this website handles information.
