All internet service providers promise blazing-fast internet speeds, low latency, and excellent reliability, but how many really deliver on their promises? If you’re suspecting that your internet service provider isn’t living up to its promises, you should perform an internet speed test to gather accurate data and either verify or eliminate your suspicion.

 

What Is Internet Speed?

internet speed what is

Internet speed indicates how fast data packets travel from your device to the internet and from the internet to your device.

Internet speed is typically measured in megabits per second (Mbps), and it can be as low as a fraction of a single Mbps or as high as 1,000 Mbps.

When measuring internet speed, it’s useful to distinguish between download speed and upload speed. The former indicates how quickly you can retrieve data packets from the internet (i.e. download a file), while the latter indicates how quickly you can send data packets from your device to the internet (i.e. upload a file).

How much internet speed you need depends on multiple factors, including your usage habits and the number of people sharing the connection. Here are general internet speed requirements based on common online activities:

  • Email and web browsing: 1–5 Mbps
  • Online gaming: 10 Mbps
  • HD streaming: 15–100 Mbps

A symmetrical internet connection (identical download and upload speed) is preferable to an asymmetrical internet connection (smaller upload speed than download speed).  

 

How Is Internet Speed Measured?

Internet speed measuring isn’t complicated:

  1. A connection is established between your device and a remote server.
  2. The transfer of a nominally sized file is initiated (100 MB is a common size these days).
  3. The time it takes for the transfer to complete is measured.
  4. The size of the file is divided by the transfer time.
  5. The result is converted to Mbps.

For example, if it takes you 10 seconds to download a 100 MB large file, then you have a download speed of 10 MBps. Because 1 MBps (megabytes per second) equals 8 Mbps (megabits per second), your download speed is 80 Mbps.

 

How to Select an Internet Speed Test Service

There are many internet speed test services out there, and their quality varies greatly. If you want to obtain the most accurate results possible, you should always choose an independent internet speed test and not one provided by your internet service provider.

Why? Because internet service providers sometimes prioritize their own internet speed test services to influence the results. Here are several official internet speed test services for popular internet service providers:

Instead of these internet speed test services, we recommend you choose any of the 10 independent internet speed test services listed below.
