How to Determine the Right Size of a Web Server?

Determining the right size for your web server is crucial as it directly impacts hosting expenses. Larger servers with extensive resources come at a higher cost. To calculate the ideal size tailored to your WordPress website’s needs, consider the following formula:

1. Average Bandwidth and the Amount of Data Your Website Serves:

Firstly, use website speed checker tools like GTMetrix or PageSpeed Insights to analyze your website’s pages. Run the 10 most popular pages through these tools to obtain the average page size in kilobytes (KB) or megabytes (MB).

Then access data from Google Analytics or a WordPress plugin like MonsterInsights to gather information on your website’s monthly page views. This data helps estimate the total number of times pages are viewed in a month.

Now, multiply the average page size (in KB or MB) by the total monthly page views to determine the average amount of data your website consumes. For example:

Average Page Size (KB) * Monthly Page Views = Bandwidth Consumed (in kilobytes)

To convert kilobytes to megabytes or gigabytes for convenience, divide the total bandwidth consumed by 1,000 (for KB to MB) or 1,000,000 (for KB to GB).

This calculation provides an estimate of the bandwidth your website requires on a monthly basis based on average page sizes and visitor interactions.

2. How Much Storage You Will Need:

To determine the storage space your website utilizes, you can track the current storage usage.

Access the Site Health tool within your WordPress admin dashboard. Navigate to “Tools » Site Health” and switch to the “Info” tab. This section provides insights into the total storage occupied by your WordPress files and databases.
