One of the most common concerns people have when deciding to host a web site is figuring out how much bandwidth they'll need. Get too little bandwidth and you might be hit with overage fees or have your web site shut off altogether. Get too much and you're paying for bandwidth that you don't really need. The following is a helpful guide for determining the amount of bandwidth that's right for your web site.

Every time someone views a web page or downloads a file, bandwidth – also known as data transfer - is used. How much is used depends on the size of the page or file that is being viewed or downloaded. Essentially, the amount of bandwidth that your web site will need depends on two key factors: (1) Web site content and file size (2) Web site traffic/popularity. Let's look at a few web site examples to get an idea of what their bandwidth requirements might be, and why.

Let's start with web sites that have high-bandwidth requirements. If you have a web site that has large-sized content and gets a huge amount of traffic, you're going to need a lot of bandwidth. An example of a web site that requires a lot of bandwidth would be http://www.compfused.com/ This web site is comprised of thousands of pages, and almost all of those pages are packed with images and video clips. Simply viewing the pages uses a lot of bandwidth, and of course downloading the video clips uses a TON of bandwidth. Combine this with the fact that this web site probably gets tens of thousands of visitors per day and you can see that its bandwidth requirements are quite extensive.
