Most Accurate Speed Test – 2022

What is the most accurate internet speed test in 2022? The simple answer is non of them are particularly accurate. The real answer is it depends on a lot of factors, and depending on what you are looking to get out of the speed test. Many popular speed test websites including and will measure your speed in different ways and give very different results.

That does not mean that one is the more accurate internet speed test it just means that the testing procedure is different. They are focused on completely different information. Depending on what you are looking to measure, one test may be better than another.

It is also best to test over a wired ethernet connection. Testing over WiFi will usually result in accurate results for internet plans of less than 200 Mbps. Testing over WiFi on a 300+ Mbps internet connection will result in a test of your WiFi speed and not your internet speed. The speed shown when running an internet speed test is a function of you local area network speed and your internet speed.

Depending on your equipment, type of internet connection, and use of a wired vs wireless connection, your limiting factor could be either your local network speed or your internet speed. With internet plans of 100 Mbps or less you are generally going to be limited by your internet speed. With faster internet service you LAN speed becomes a critical piece of the puzzle. This is why for speed over 200 Mbps testing over WiFi will not give you an accurate result.


Ookla’s is perhaps the most widely recognized name in the speed testing industry. is ideal for testing your internet connection under ideal conditions to a server that is close to you geographically. This will usually result in a higher result than seen on other speed tests. This does not make it more or less accurate of a speed test. When you use it is best to use the preselected server in most cases.

If your results are lower than expected, try the next server down on the list. It is possible that the initial server that was automatically selected was over crowded during the test. By testing using a couple of servers you will get a better overall picture of the speed of your internet connection.

The most useful way of using is to determine if you are getting the internet speeds you are subscribed to. You should be getting at least 80% of the speed you are subscribed to if you are testing over a wired connection.

If you are getting significantly less than 80% of the bandwidth you are subscribed to something is wrong. It could be with your internet service provider or it could be with your device. Reach out to your internet service provider (ISP) for assistance. is one of the leading websites for measuring internet bandwidth. It is one of the most accurate internet speed tests.

The less hops between your device and the testing server, the less chance for data congestion that could result in slower speeds.

Comcast’s Xfinity speed test is a great tool even if you do not use Xfinity internet service. It is a great test to run in tandem with Generally your results will be within 10% of each other.

3) is a unique speed test. It is hosted by Netflix and tests your internet connection to Netflix’s servers. This is useful for troubleshooting Netflix streaming issues. If you are experiencing buffering when streaming Netflix this is the test for you.

Your results are often going to be lower than on the other speed testing websites. This is especially true if you have an internet connection of 100 Mbps or faster. A 4K Netflix stream uses a maximum of 25 Mbps. For this reason they have no interest in whether you are getting anything higher than that. The speed test does not accurately measure speeds over 100 Mbps. For this reason I would not recommend using as a general speed test. I would however recommend for troubleshooting Netflix streaming issues. is not the most accurate internet speed test in 2022 for general testing, but it is definitely helpful in troubleshooting Netflix streaming issues. If you are getting less than 5 Mbps you may have issues streaming in HD and if you are getting less than 25 Mbps you may have issues streaming in 4K.

Some internet service providers (ISPs) restrict your connection speed to services such as Netflix in an attempt to reduce your data usage. This is most common with cellular based internet connections. Generally it is clearly stated in the terms of service you agreed to when you signed up for service. This speed restriction is commonly referred to as throttling, deprioritization, traffic shaping, or network management.

In most cases this is undesirable, but in some cases this is actually a good thing. If you have a limited size data bucket for the month, automatically streaming at a lower resolution depending on the device type may not be a bad thing. You will be very hard pressed to tell an HD stream from a 4K stream on a smartphone display. You will however notice when your data lasts several times longer. Fast Speed

A Much More Accurate Way to Test Your Internet Speed

It should also be noted that the most accurate way to measure your download speed is to download a large file from a server with known fast download speeds and to calculate your internet speed. The formula for calculating download speed is a follows.

File size in gigabytes, multiplied times one thousand, multiplied times eight, divided by time in seconds equals your download speed in megabits per second. This is the standard unit of internet bandwidth (speed). If you time is in minutes convert it to seconds prior to dividing by multiplying by sixty. For example if a 2.2 gigabit file downloaded in 2 minutes 11 seconds it would look like this.

2.2(1,000)(8) = 17,600

2 minutes 11 seconds = 131 seconds

17,600 / 131 = 134.35

Your internet speed would be 134.35 megabits per second. This is the most accurate way to test your internet speed. Just make sure the server you are downloading from is fast enough to not limit the test. Downloading a Linux ISO is a recommended method.


Overall speed testing websites give a good general overview of your internet connection speed but do not always give the most accurate results. If you want to get a more accurate real world result, downloading a large file from a fast server and calculating your speed is your best option by far.
