Lessons From Webhostingology-How Much Bandwidth Do I Need For My Website?

Often, when you are planning your website and choosing the right web hosting service, estimating your bandwidth requirement is essential. And even if you are already a seasoned website or blog owner, you can easily be overwhelmed by the wide range of bandwidth offers from web hosting companies. In this article, Webhostingology-the science of webbosting– provide their definition of bandwidth.

What is bandwidth?

Alex Papaconstantinou, founder of Webhostingology, explains that bandwidth refers to the level of site traffic and the amount of data that can be transferred between a website, its users and the internet. Usually, every package a web hosting company offers has some maximum level of bandwidth.

Bandwidth, together with things like storage, website security and price are some of the most important technical aspects of web hosting. The more bandwidth a hosting company can provide the better and faster services it’s likely to offer.

How Much Bandwidth Does Your Website Need Per Month?

How much bandwidth your website needs will depend on various factors like how big your website is, that’s whether it’s for a large enterprise, medium or small business. However, whatever the factors, there is a simple formula you can use to easily find out how much bandwidth your website really needs to adequately support the traffic on it. Knowing how much bandwidth you need will help you evaluate offers from various hosting companies and select the right package. Here is the bandwidth formula as provided by Webhostingology:

Bandwidth = Daily Visitors x Daily Page Views x Average Page Size x 31 x Tolerance Number.

As long as your website does not offer file downloads, this formula will help you determine how much bandwidth your website needs. However, if you have some downloadable content, the formula gets somewhat complicated, but it’s still easy to use.

Bandwidth = (Daily Visitors x Daily Page Views x Average Page Size) + (Daily File Downloads x Average File Size in KB) x 31 x Tolerance Number.

When using this formula, work out the values in brackets first.

Here is what the elements in the equation mean:

Daily Visitors (average) – This number of visitors you expect your website to have per day. Working it out day-by-day can complicate it, instead, simply calculate the average number across the month.

Daily Page Views (average) – Calculate the average across the month.

Average Page Size (in KB) – This is the average size of your site pages with all things included.

Daily File Downloads (average) – The number of daily content downloads from your website in terms of all additional files that are independent of your site pages.

Average Downloaded File Size (in KB) – Determine the average size of a file that can be downloaded from your site. Always err on the caution side, go bigger if you are not sure. 

31 in the bandwidth formula is the maximum number of days a month can have. Most web hosting firms calculate bandwidth allowances on monthly bases, that’s the reason the 31 appears in the formula.

Tolerance number – This is typically a “room for error.” So, for instance, if 1.5 is your projection, make this number 1.80 or 2. This depends on how confident you’re in your estimations. Webhosting expert, Alex Papaconstantinou, from, recommends that you should aim for a higher value if you think your website may grow quickly!
