Whether you’re thinking about switching to a new broadband deal, or just curious about your current internet speed, there’s a lot of information to take in. Read our most popular questions and find out how you can get the most out of a speed test.
⚡️ Speed information
You should run a broadband speed test to help you decide whether it’s time to upgrade your broadband to get faster internet or if you need to contact your provider because you’re not getting the speed you’re paying for.
Broadband speed is affected by a few things, including:
To get the most accurate results from a broadband speed test, you can:
Broadband speed is measured in megabits per second (Mbps) – ‘mega’ as in ‘million’, and ‘bits’ meaning ‘bits of data’.
A broadband speed test calculates how many bits of data your device can download per second.
So for example, your device might be able to download 30 million bits of data per second, which would be shown as 30Mbps. Put in context, a good quality photo is about 2 million bits (2Mb), so based on an internet speed of 30Mbps, you could download 15 photos in one second.
Ping is how responsive your internet is and it’s measured in milliseconds (ms) – so the lower the number, the quicker your internet is.
For example, if you’re trying to move an image on an online document, a good ping is if the movement happens instantly. If there’s a noticeable delay, then your ping rate isn’t as good.
When you do anything using the internet, data is broken down. The pieces or ‘bits’ are sent where they need to go and then put back together again. If there’s a delay sending some of these bits, this causes jitter.
You might have experienced jitter as choppy audio on an online call or if a film you’re watching becomes blurry.
Upload speed is how fast what you’re doing is sent through the internet.
Video calls and screen sharing are examples of uploading. Online gaming does both downloading (so you can see what other gamers are doing) and uploading (so the others can see what you’re doing).
