What is Bandwidth and how can i Calculate it?

August 18th, 2009

Bandwidth is the amount of data that can be transferred to and from your account in one month. Every time someone downloads a 10 KB file from your website, they use 10 KB of bandwidth from your account.

Also, every time someone visits your site; they are downloading the home page and use that much bandwidth.

Bandwidth is reset on the 1st of every month on all accounts.

How to calculate your monthly bandwidth requirement?

Lets assume, you have only 1 page on your website which is of 50 KB in size (text+graphics). When you get one visitors on your webpage and uses up 50 KB of your bandwidth. If your monthly Bandwidth is 1 GB (1024 MB or 1048576 KB) then 1048576 KB / 50 KB = 21000 approx. This is the total number of visitors you can get monthly on your website before your bandwidth reaches it’s limit. This is a simple estimation and you will have to take into account the number of pages on your website together with your email usage to calculate the correct bandwidth.

Note: You can optimize your bandwidth usage by designing pages which have their CSS and HTML validated. Make sure the images you use are fully optimized. As a rule of thumb, photographs should be saved in .jpg and other graphics should be saved in .gif. Further more .jpg can be optimized by reducing the quality of the image or the size.
