How Much Hosting Bandwidth do You Need?

If you are creating a new website, you have a lot you need to consider.

Which web hosting plan to use?

What will your domain be?

One of the main questions you may be asking is, “How much hosting bandwidth do I need?”

Depending on the size of your website and the number of visitors, this number can fluctuate.

It can be difficult to estimate how much bandwidth you’ll need. You don’t want to have too little or pay for too much hosting bandwidth.

Read on to find out how you can determine the exact amount of bandwidth you’ll need for your new website.

Basics of Hosting Bandwidth

In simple terms, your hosting bandwidth is the amount of data that is allowed to move throughout your site.

Let’s sum up bandwidth with an analogy.

Imagine your bandwidth being a track with runners on it. If there is only one lane, the runners will be held up from going any faster.

So the more bandwidth you have, the faster your visitors will be able to access pages on your website.

If you are starting your website from scratch, you’ll need to figure out how much you will need to make your website efficient for your viewers.

Web hosting services will give you several options for your needs. The more bandwidth you need, the more you’ll pay.

So you want to make sure that you are not overpaying for bandwidth. But you also want to ensure that you’re not caught with too little hosting bandwidth.

Guessing how much bandwidth you need isn’t a great idea. Thankfully there is a mathematical way you can know exactly how much hosting bandwidth you’ll need.

We’ll show you how to calculate the amount of bandwidth you’ll need with simple calculations.

  • Calculating Bandwidth
  • First, you’ll need to figure out how large your page is. For this, you can estimate your page size in kilobytes. Your web hosting service may have this information.
  • Next, you’ll need to find the average amount of visitors you have each month. Take your website size and multiply the average number of visitors.
  • You will then take that number and multiply it by the number of views each visitor has made.

Your math should look like this: Page size in KB x Average monthly visitors x Page Views x 30 (days in the month) x Safety factor.

Your safety factor should be a number that will give you some space to grow. This number should be either 1 or larger depending on how much you think your website will grow in the future.

If you believe that your website will grow substantially, make sure you’re using a larger number for the safety factor.

Once you’ve done the math, the end result will give you the amount of hosting bandwidth you will need for your current situation.

Remember that things change.

Make sure you’re taking changes into account when you’re deciding on bandwidth.

Consider Changes When Choosing Bandwidth

As stated previously, you should have a general idea of how many visitors your website has monthly.

If your website garners a high amount of traffic each month, you want to make sure your website can handle it.

Remember that traffic can change throughout the year, so you should take into account how these changes can affect how much hosting bandwidth you’ll need in the future.

You should also consider the layout of your page. Some things to consider when you are laying out your website:

  • The size of images used on your website
  • Any videos, large or small
  • Number of files downloadable by your visitors
  • Complication of your website design

The above factors can use more hosting bandwidth. Cut down on bandwidth usage by:

  • Reducing image sizes
  • Reducing the amount or size of files your users can download
  • Minimizing your website design
  • Limiting the number of videos you add to your website

You should also ensure that the web hosting service you choose will let you change your plan depending on these changes.

You can predict how much bandwidth you will need for your website, but things do change.

Unlimited and Unmetered Bandwidth

Bandwidth is measured in gigabytes. Generally, web hosting companies will give you an idea of how many gigabytes are used per each plan offered.

When you are choosing how much bandwidth you’ll need, you may be offered an unlimited amount of gigabytes.

You should be cautious of this option. Unlimited bandwidth does not always mean it is truly unlimited.

Unlimited bandwidth seems like the easy option. But many web hosting services only give you a part for free. Some web hosting services only allow the first 5 or 10 GB for free.

The rest of the bandwidth you use can result in extra charges. This can cost you more in the long run.

Some web hosting services do offer unlimited bandwidth. For example, Dream Host offers unlimited bandwidth for less than $9 a month.

Depending on your situation, unmetered bandwidth could potentially be a better option for you. Web hosting companies allow you to pay a specific rate and you’ll be able to use as much bandwidth as you need.

With unmetered hosting bandwidth you the data you transfer will not be monitored by the web hosting company.

However, the web hosting company could limit your website with the amount speed, therefore slowing down your website.


There is plenty of factors to consider when creating your website.

Making sure you have enough hosting bandwidth is one of them.

You want to ensure that your website can handle the traffic that will amass as your website grows.

Taking into account how your website is set up is also a factor in deciding on bandwidth.

It may seem like a lot of math and investigation. But making sure your website is capable of accommodating to your visitors and content is important.

If you’re still not sure how much bandwidth your website will need, contact a professional who can help you decide on a web hosting plan that will work best for you.
