One of the best things about broadband internet is the high-speed connection that comes with it. Internet browsing used to feel more like crawling than surfing, but using broadband means web pages can be loaded almost instantly.

It also means you can download a huge amount of songs, films, and other media to your desktop without a long wait. It is easy to let this new freedom go to your head and opt for a broadband package with unlimited downloads - however many find that they only use a fraction of this allowance, meaning they end up paying out for more than they need.

So how do you figure out what download limit you really need? We show you how to assess your own broadband usage to determine which limit is right for you.

What is a download limit?

A download limit is the maximum amount of data that you can transfer from the internet to your computer, usually expressed as an amount of gigabytes. A gigabyte (GB) is equal to around 1000 megabytes or one billion bytes, which are used to measure units of information. Most broadband packages will specify how many gigabytes users are allowed to download each month.

In practical terms, this means that a 1GB limit would allow you to download around 10,500 web pages, 100,000 emails, or around 400 average-sized images or music files each month.

Download limits generally range from 1GB a month to around 40GB, and some packages impose no limit on how much you can download per month. When signing up for a broadband package you will have to identify how much you and the people you live with are likely to download each month and then choose a suitable limit accordingly.

Light Internet Usage: 1-10GB

Those who use the internet for moderate surfing and never download more than the occasional film or song have a real opportunity to save money on their broadband bundle by going for a low download limit. If your main activity on the internet consists of browsing, sending and reading emails and occasionally streaming videos or music, there is no need to be paying out for a package whose download limit is infinite.

Generally if you go for the lowest download limit of 1GB you will be able to look at up to 10,500 web pages and download 205 mp3 songs (equivalent to about 20 albums) each month. This may well be adequate for you if you do not use the internet very often, or if you do not tend to download or stream TV, radio, movies, or music.

However it is worth noting that if you do go for a low download limit you will have to be certain that you will not need more than your set amount per month - some broadband providers will charge you extra if you exceed your set limit. So this is something worth taking into consideration when deciding which limit to go for. However, this charge generally will not be extraordinarily high so it may be cheaper to exceed your limit occasionally rather than pay for a higher download limit - but it is still worth checking all the associated costs of your package.

Medium Internet Usage: 10-20GB

If you think you may stray beyond a 10GB limit you may be more suited to a slightly higher limit, but still do not need to opt for unlimited downloads. Medium internet users who download a few movies or songs per month, and use their internet connection daily.

Around 15GB will enable you to look at around 157,000 web pages a month and download 3070 mp3 songs (equivalent to about 300 albums). So a slightly higher download limit may be suitable for you if you think your internet usage would fall into this group. Remember again though that if you exceed your limit you are likely to be charged - though this is unlikely to be something for you to worry about if you only use the internet moderately.

Heavy Internet Usage: 20-40GB

Generally speaking a 30GB limit will enable you to look at around 314,500 web pages a month and download about 6145 mp3 songs (equivalent to about 600albums). If you think you are likely to exceed a 30GB limit then you might consider getting a download limit of up to 40GB per month.

This is particularly applicable to people who use the internet very frequently, download software, video and music regularly, stream video and music content or play online games. However if you expect that you will need more allowance than this you can opt for 'unlimited' broadband, which will allow you to download as much as you want per month with little restriction.

Unlimited Downloads

The word 'unlimited' alone can make the internet package sound like the most exciting one to go for, but look beyond the sales pitch and consider what you really do need from the internet. If you frequently download films, songs, TV, and so on, or if you are a keen internet gamer, or if internet surfing is one of your favourite pastimes, having no limit on the amount you can download may suit you. However it is worth bearing in mind that you only really need an unlimited connection if your internet use is excessive.

Also it is important to note that many unlimited download packages are not in fact as 'unlimited' as they seem to be - many broadband providers impose a 'cap' on how much you can download. This means that if you go over a certain very high limit your service may be temporarily suspended or you may be charged. This generally is not something to worry about though unless you use the internet very excessively, to the point that other users' connections are suffering.

If you take a look at how much you do download on average per month, you should be able to find a broadband package with the right download limit for you - meaning you are not paying out unnecessarily for a limit you never reach.
