Let’s do some calculations on the actual average usage of a WordPress site. The below data is an average disk space usage taken from a pool of production WordPress sites that have been running for 4+ years.
- WordPress core: 8.9 MB (4.9.5+)
- Average plugins directory (
/wp-content/plugins): 100 MB - Average theme directory (
/wp-content/themes): 25 MB - Average uploads directory (
/wp-content/uploads): 825 MB - Average MySQL database: 85 MB
On average, we’ve found that the typical client has approximately 1 GB of data for a single WordPress installation. Sometimes this can swing in either direction. Some might have a much larger database, but smaller file usage, or the other way around. So on our starter plan, this leaves you with another 4 GB (80%) of unused disk space for growth.
Live Examples
But let’s take a look at some live client examples. The sites listed below are all in production: including blogs, businesses, and ecommerce sites.
Client 1
Client 2
Client two has 3 WordPress sites and is using 3.3 GB out of their 20 GB disk space allotment. They are pretty much on par with the Kinsta average of 1 GB per site.
Disk usage example (client 2)
Client 3
Client three has 3 WordPress sites and is using 503.21 MB out of their 15 GB disk space allotment. They are significantly below our Kinsta average, using less than 200 MB per site.
Client one has 11 WordPress sites and is using 4.04 GB out of their 100 GB disk space allotment. They are well below our Kinsta average, using less than 400 MB per site.
