Internet testing

Am I getting the internet speed I pay for?

Internet Speed Test

Your internet feels slower than it should, and you want to know what you are really getting.

Is this happening to you?

  • Videos stop to load in the middle of a programme.
  • Pages take a moment to appear after you tap a link.
  • You pay for a fast plan but it does not feel fast.

This test measures your download speed, your upload speed and your response time.

Does this sound familiar?

Three ordinary evenings that end up on this page.

  • You sit down to watch a film in the evening.

    The picture goes blurry, then stops to load.

    This test shows what your connection is really delivering.

  • Your provider promised a fast plan.

    Nothing in the house feels as quick as promised.

    Now you have a number you can hold them to.

  • One room in the house always feels worse.

    The same phone works fine next to the router.

    Testing in both places tells you where to look.

Can this help me?

Yes, if you want to know what your connection actually delivers to this device right now.

Why would I use this?
It shows what your connection really delivers right now.
When should I use this?
Use it when your internet feels slow, or after you change something.
What will I learn?
You learn your speed, your response time and what they allow you to do.

What it will not tell you: It cannot tell you which company or which device caused a slow result on its own.

What does this mean for me?

Here is how to read the numbers you get back.

  • The first number is how quickly things arrive on your device, such as films and web pages.
  • The second is how quickly things leave it, such as photos, backups and your camera on a call.
  • The third is how long your connection takes to answer, which is what makes it feel quick.

Everyday use

Sizes and speeds are easier to judge with a familiar example.

  • One HD film on the television · 5 Mbps

    A single HD stream needs about 5 Mbps of steady download.

  • A family evening with four devices · 50 Mbps

    Several streams and calls at once need far more headroom.

What should I do?

  1. Compare the result with what your provider promised you.
  2. Run it again with a cable to your router, if you can.
  3. Test once more at a quiet time of day and compare the two.

What happens if I ignore this?

If you do nothing, you keep guessing whether your plan or your home is the problem.

Check if this is the problem

Run a self-check when you want to test one change at a time.

Common questions

Does this test use real network traffic?
Yes. It moves real data to and from a Measurement Lab server.
Why is my result lower than the speed I pay for?
Wi-Fi, other devices and busy times all reduce what one device sees.

Technical details

The words behind the numbers, in case you want them. You do not need any of this to use the tool.

Mbps
How much data can move each second. Bigger is faster.
Latency
How long your connection takes to answer, measured in thousandths of a second.
Throughput
Another word for how much data actually got through.

What you get back

  • Download speed (Mbps) — How fast data reaches you.
  • Upload speed (Mbps) — How fast data leaves you.
  • Latency (ms) — How long a round trip takes.
