Whether you're downloading GTA 6, a new console game or a 4K movie, your broadband speed makes a big difference to how long you'll be waiting.
Use our free download time calculator to estimate how long a file will take to download at speeds between 100 Mbps and 1,000 Mbps.
Simply choose a file, adjust the broadband speed slider and see your estimated download time instantly. You can also compare how much time a faster connection could save you.
From everyday browsing to gaming and 4K streaming, different households have different needs. Discover how faster broadband can reduce download times, keep your devices connected and make everyday life that little bit easier.

Browsing, video calls, online shopping and a favourite series in the evening? You might not need the biggest package to enjoy a smooth everyday connection.
One person is on a work call while someone else streams or downloads. A little more bandwidth gives your household extra headroom when things happen at once.


Homework upstairs, a game update downstairs, a 4K film on the TV and parents working late. Faster broadband can make large downloads less disruptive to everyone else.
Multiple demanding users, huge game downloads and busy connected devices? Gigabit broadband can dramatically shorten large downloads when your equipment and download source can keep up.

Not sure which broadband package suits your household?
Use our broadband usage calculator to find the right speed based on how many people and devices use your connection.
Life doesn't slow down, so why should your broadband? From downloading your favourite games to keeping the whole family entertained, faster full fibre gives everyone more freedom to do what they love online. Less waiting, fewer compromises and more room for whatever comes next.

Is there really anything worse than waiting around for your new game to download? We don't think so. Skip the wait and get quicker access to the things you love.

Need some time to yourself? Stream to your hearts content in another room without ever bothering the rest of the family.
You never know what life is going to throw at you. As your household naturally grows and adds devices, it'll naturally demand more from your internet connection. A faster package gives you extra headroom - meaning the whole household can stay connected - always.

To calculate download time, multiply the file size in gigabytes (GB) by 8,000, then divide by your broadband speed in megabits per second (Mbps).
For example, downloading a 25 GB file at 100 Mbps would take approximately 33 minutes and 20 seconds under ideal conditions.
Our free download time calculator does the maths for you. Simply select a file and adjust the broadband speed slider to see your estimated download time.
The time it takes to download a 100 GB game depends on your broadband download speed.
Estimated download times:
These estimates assume your broadband connection maintains its full download speed. Actual times may vary depending on your WiFi connection, network congestion and the game download server.
Using a 210 GB example download size for GTA 6, downloading the game would take approximately:
These calculations assume your broadband connection maintains its full download speed throughout. The 210 GB figure is an example used by our calculator, not an independently verified official game size.
Use our GTA 6 download time calculator above to compare how different broadband speeds affect your estimated waiting time.
Mbps stands for megabits per second, while MB/s stands for megabytes per second.
Broadband providers advertise internet speeds in Mbps, whereas game launchers and file download applications may display speeds in MB/s.
There are eight bits in one byte, meaning a 100 Mbps broadband connection can theoretically download data at up to 12.5 MB/s.
Understanding the difference helps explain why a 500 Mbps broadband connection doesn't display 500 MB/s when downloading games or files.
Our download time calculator estimates how long a file should take to download based on its size and your selected broadband speed.
However, actual download times can be affected by several factors, including WiFi signal strength, other devices using your connection, network congestion, your computer or console, and limitations imposed by download servers.
For the most consistent download speeds, consider using a wired Ethernet connection and pausing other large downloads while downloading your game or file. Checkout our blog for more tips and tricks on how to get the most our of your broadband.
