How much bandwidth do I need?

When choosing a host, the amount of bandwidth you choose to purchase can be crucial to the success of your site. Generally speaking, the more amount of bandwidth you have, the more traffic your site will be able to handle at one time.

To determine how much bandwidth you will need, you must estimate how big each page on your site is and how many people are going to view it. To do this, add up the size of every image on the page and the size of the page's HTML files, and multiply that by the amount of views for that page you expect per month.
For example, if you had three 10k images on your page and a 2k HTML file, you would have 32k of data on that page. Multiply that by your expected page views (let's say in this case it is 100,000 per month), and you get 3.2 G of data to be transferred that month for that page. Now calculate this for each page, and you will know approximately how much bandwidth your entire site requires.
