The top internet speed test sites for measuring your internet speed

A speed test is an online tool to measure your internet speed. Most speed tests measure your upload and download speeds, while some may measure just your download speed.

A speed test is a helpful tool for ensuring you’re getting the internet speeds you’re paying for or testing the strength of your connection in different areas of your home. If you have a fast internet plan but are getting slow internet speed test results, you can determine if you’re overpaying for your service.

You can use a handful of free online internet speed tests to test your internet connection. We list some of our top picks below.

Best overall internet speed test: Ookla’s Speedtest.net

Ookla’s Speedtest.net is our top pick and also one of the most popular speed tests out there. It measures your download speed, upload speed and ping time. Ookla also immediately records information regarding your connection type, internet provider and location. Once you take the speed test, your results are saved in your history so you can go back and compare multiple speed tests.

Ookla also offers mobile versions of the speed test and a desktop app for your device.

Most accurate speed test: TestMy.net

TestMy.net offers multiple testing options for measuring your internet speed online. You can especially test your download speed, upload speed and latency. TestMy.net also uses HTML5, which allows for more accurate results.

TestMy.net also provides detailed results within each speed test metric and allows you to compare them on its results page. You can view them in graph format for a more visual representation of your speed test. You can also personalize your speed test with TestMy.net’s customizable test size and duration options.

Easiest to use: Fast.com

Fast.com is our pick for the easiest-to-use online speed test. When you land on the site, it starts measuring your speed immediately — you don’t even have to click a single button. Like most tests, Fast.com measures your upload speed and latency. On the other hand, its interface is a bit bare-bones compared to other speed test options, but it gets the job done.

Fast.com is also a tool owned by Netflix. It is designed to test your internet connection to ensure it is strong enough to support streaming Netflix in maximum resolution. This makes it a great choice for streamers testing their connection for optimal streaming performance.

Best mobile speed test: SpeedTest Master 

SpeedTest Master is a widely used speed test app for mobile internet speed testing. It’s available on iOS and Android devices and measures upload speed, download speed and latency. It uses multiple servers to test your speed, so it’s known for its accurate and reliable results.

The SpeedTest Master app also provides a network diagnostics feature to help you troubleshoot any network issues, like a weak Wi-Fi signal. It also analyzes multiple Wi-Fi signals to determine the strongest one, which is especially useful if you are traveling or in a public area with multiple networks to choose from.

Best ISP speed test: Xfinity

Most internet provider speed tests are similar, but we like Xfinity’s because it offers insight into the types of internet activities you can do with the current internet speed you’re getting.

It measures your upload speed, download speed and latency. Once your results come through, you’ll get a list of activities your speed can handle. For example, a speed test with results of around 320 Mbps download speed can handle the following activities, according to Xfinity:

• Send/receive email
• Browse the internet
• Stream HD video
• Stream 4K video
• Speedy downloads

We also appreciate Xfinity’s “Expecting more speed?” button. If you aren’t happy with your results, Xfinity offers information about internet plan speeds, the speed you need and how this can affect your speed test results.

Importance of regular speed testing

You should test your internet speed regularly to ensure your network performs at the top of its game. While you can use these tests to learn what speed you’re getting, they are most useful in determining if a glitch in your network is causing slow internet speeds or if your plan isn’t delivering the speeds you pay for.

If you consistently get slower speeds than what you’re paying for each month, you can reassess your internet provider, plan or even technology type. Learning the ins and outs of your internet service can sometimes feel daunting, but a speed test is a quick, easy and free way to help you gain insight into your internet plan.
