When you are buying insufficient bandwidth, you might find yourself in two undesired situations: paying, usually high fees, for the extra bandwidth your web site needed or having your web site shut off. Overbuying bandwidth is not a good thing either as it will put you in the position to pay for something you don’t use. This article is intended to help you determine just how much of bandwidth your web site requires.
What is bandwidth anyway?
Let’s just see what bandwidth is. Bandwidth is the term that is used to denote the amount of data that has been transferred from your web space to the computers of your visitors. To put it simple, bandwidth is the amount of data that flows across a network wire in a given period of time. In web hosting industry this time period usually is one month. This happens simply because web hosting providers are also charged monthly for their huge broadband Internet connection. This is the cost that ultimately is then passed on to the consumer in the form price for their individual web hosting plan.
Bandwidth being such a delicate matter for a successful web presence, could you at least estimate the bandwidth needs of your web site? The answer is yes, you can estimate it, but you can never be sure of your estimate being perfectly correct because of all the variables involved.
How do I calculate my bandwidth?
If your index.html page has a size of let’s say 50 KB, every time you get a visitor on your start page (assuming that your visitors will only open you first page and not browse your entire web site), your visitor will download 50 KB of information onto his or hers computer. For 100 visitors, you will get a total of 5.000 KB of data being transferred from the web server hosting your site to your visitor’s computers.
So a formula for computing your estimated needs of bandwidth would look like this:
Size of your web content * number of visitors that accessed that web page = your consumed bandwidth
