How to calculate your website’s bandwidth requirements?

Before purchasing your ideal web hosting plan, several factors should come into play to help you make a good decision. One such factor is the bandwidth the hosting plan allocates your website.

How to calculate your website's bandwidth requirements

Simply put, a website’s bandwidth is the amount of data that’s usually transferred from the host to the specific visitor’s device in a particular amount of time. Unlike the case of a depleted disk space where all you need is to delete several files to create space, a depleted bandwidth can lead to a site shut down. This can be especially prevalent if your site experiences a visitor surge or an enormous increase in downloads on the site.

With numerous options of web hosting providers now available, there is no shortage of hosting plans to select from today. As such, you need to evaluate several viable plans that offer enough bandwidth without causing a site shutdown. Majority of users do not truly understand how to determine how much bandwidth their sites need for seamless functioning. For this reason, we have outlined a few key factors to consider that will simplify the process of calculating the right amount of bandwidth for your site.

How to Calculate the Right Amount of Bandwidth For Your Website

It’s pretty easy to calculate the amount of bandwidth your website requires. All you need is to collect several statistical data and use them to make a simple calculation. Some of the key data you require include;

  • An estimate of the number of visitors your site receives daily
  • Average size (KB) of your web pages
  • The average page views per each visitor

Having collected the data above, multiply your findings by 30 which is the average number days in a month. However, be sure to calculate the total bandwidth for all your websites especially if you’re using a single hosting account to host several sites.

Consider increasing your bandwidth

Bandwidth calculation

Using the earlier mentioned method, what you get is just the estimate of the bandwidth you require for your site. However, it’s important for you to understand that these estimates can be deceiving with the results in real world situation proving to be quite different. For example, let’s look at this scenario- your site receives 1000 visitors per day on average, has an average page size of 45KB and each of your visitors views an average of 4 pages. In this case, all you need is 4.5GB worth of bandwidth on paper. However, this amount of may not be sufficient due to the following reasons.

1. File downloads

If your site contains files that visitors can download, you’ll need to allocate more bandwidth to accommodate those downloads. As such, you’ll need to calculate the average size of the download files, and the projected number of downloads. Multiply your findings with the result you get from your theoretical bandwidth requirements.

2. Multimedia

If your site contains any form of multimedia files such as videos, music, and flash animations, you’ll need to allocate more bandwidth to support them as well. If, for example, your site runs an estimated 4.5GB bandwidth, your site can only allow up to 22.5 downloads of a video sized at 200MB.

3. Increasing traffic

If you’re serious about growing your site and thus offering high-quality content to your visitors, it is inevitable that your traffic will grow by day. This increase may translate to more page views and more downloads than you had earlier anticipated. Over time, this growth will demand that you add more bandwidth which is why it’s prudent to leave some allowance when doing your initial bandwidth calculations.

4. Changes in layout

Once every while, it is normal to want to change your site’s general layout especially if you’re tired of its current looks or need an upgrade. However, it’s important to understand that doing this may lead to an increase in the size of your web pages which results in increased bandwidth demands.


Looking at the post above, it’s easy to tell how important having the right amount of bandwidth is for your site. Besides, it’s also crucial that you consider other supporting aspects such as your host’s server speeds, uptime, pricing and customer support. This way, you can enhance your website’s efficiency and speed which enhances its profitability.
