What is bandwidth and how much is enough?
It depends (don’t you hate that answer). But in truth, it does. Since bandwidth is a significant determinant of hosting plan prices, you should take time to determine just how much is right for you. Almost all hosting plans have bandwidth requirements measured in months, so you need to estimate the amount of bandwidth that will be required by your site on a monthly basis.
If you do not intend to provide file download capability from your site, the formula for calculating bandwidth is fairly straightforward:
- Average Daily Visitors x Average Page Views x Average Page Size x 31
If you intend to allow people to download files from your site, your bandwidth calculation should be:
- (Average Daily Visitors x Average Page Views x Average Page Size) + (Average Daily File Downloads x Average File Size)] x 31
Let us examine each item in the formula:
- Average Daily Visitors – The number of people you expect to visit your site, on average, each day. Depending upon how you market your site, this number could be from 1 to 1,000,000.
- Average Page Views – On average, the number of web pages you expect a person to view. If you have 50 web pages in your web site, an average person may only view 5 of those pages each time they visit.
- Average Page Size – The average size of your web pages, in Kilobytes (KB). If you have already designed your site, you can calculate this directly.
- Average Daily File Downloads – The number of downloads you expect to occur on your site. This is a function of the numbers of visitors and how many times a visitor downloads a file, on average, each day.
- Average File Size – Average file size of files that are downloadable from your site. Similar to your web pages, if you already know which files can be downloaded, you can calculate this directly.
Usually, hosting plans offer bandwidth in terms of Gigabytes (GB) per month. This is why our formula takes daily averages and multiplies them by 31.
