One thing that I have noticed in the last few years is that my hosting packages have started approaching their Disk Space and Inode limits. Even packages that contain just a few small WordPress websites, for some reason these keep on growing in resource usage, even if there’s no new content and very low traffic.
Back in September 2018 I thought I found my culprit, something that I wrote about in my clickbait-ey article WordPress Image Sizes: a Ticking Time BOMB?.
WordPress got big and continues getting bigger
Have you ever wondered by how much WordPress has actually changed in the last 10 years? What’s the difference between WordPress 3.0 and WordPress 5.0? That’s exactly what I decided to look at.
Package Size of Major WordPress Versions
In the last 10 years, WordPress has grown from 5.38 MB and 603 files to 38.0 MB and 1,713 files. It has grown in size by over 600% and has tripled the number of bundled files.

|5.1||February 21, 2019||38.0 MB||1,713 Files in 173 Folders|
Package Size of Popular WordPress Plugins
The WordPress dashboard does not show a lot of data about the plugins that we can so easily install. It will only show the current version and the developer of a plugin. But have you looked at the amount of files that we so easily put on our web servers?
Here’s a mockup of what it could look like, which would maybe convince users to really think about the dozens of plugins that they casually install on their websites.
Jetpack alone is close to 20 MB in size and has almost as many files as WordPress itself – 1,467 files.
The very popular The Events Calendar plugin is even more ridiculous – 58.2 MB in 1,992 files. Imagine – something bigger than WordPress itself is there just to add a page with upcoming events. It is installed on more than 700,000 websites and uses more than 40 TERABYTES of data in 1.3 BILLION files (1,394,400,000). All this data is stored and is constantly powered across tens of thousands of servers.

Package Size of Popular WordPress Themes
I have looked only at some of the most popular free WordPress themes in the official WordPress.org theme repository. Even here some themes have a worrying size.
What’s the situation with premium themes like Avada and Divi? Can anyone share the data in the comments section below?
|WordPress Theme||Theme Version||Folder size||Total files|
|Ashe||1.8.2||5.41 MB||98 Files in 26 Folders|

The Size of a Simple WordPress Website
If a regular WordPress user installs just a few of the most popular plugins (Advanced Custom Fields, Akismet, Contact Form 7, Cookie Notice, Jetpack Really Simple Captcha, Wordfence, Yoast SEO and WP Super Cache), then that’s a total of 55.9MB in 3,393 files and 568 folders. This is of course without all the data that is stored in the database.
If you add that to a clean installation of WordPress 5.1, a popular free theme like Hestia, then just your website’s files without the database will reach ~102 megabytes, 5,463 files and 845 folders.
Currently WordPress powers over 60 million websites, that is an estimated ~33% of the Internet. Some of these websites are large websites with tens of thousands of content pages. But a vast majority of WordPress websites are run by regular people and small businesses, many of them with probably less than 20 pages of content.
Now imagine that these millions of WordPress websites rely on thousands upon thousands of files, hundreds of megabytes worth of scripts and libraries, just to output a few hundred of cached kilobytes of “Hello World” content.
WordPress Websites and the Environment
Our major finding is that the Internet uses an average of about 5 kWh to support the utilization of every GB of data, which equates to about $0.51 of energy costs. Only 38% of those costs are borne by the end-user, while the remaining costs are thinly spread over the global Internet through which the data travels; in switches, routers, signal repeaters, servers, and data centers. This creates a societal “tragedy of the commons”, where end users have little incentive to consider the other 62% of costs and associated resources.
If we were to transform these values into CO2 emissions, then according to CarbonFund.org, on average, electricity sources emit 1.222 lbs (0.55 kg) CO2 per kWh. The same amount of CO2 emissions come from burning of 0.773 lbs (0.35 kg) of coal, by charging 90 smartphones or by driving 1.7 miles (2.73 km) an average passenger vehicle.
Having said that, do you think that WordPress websites are good for the environment? Is it worth keeping 100+ MB worth of CMS files just to output a few content pages, pages that we end up transforming into cached, static files?
But what is there to do?
Please understand that I’m not criticizing WordPress as a whole. I simply want to point out that WordPress has grown so big in all these years, that it is no longer a sane choice for building simple landing websites, one-page websites and other types of small-scale websites.
You don’t buy a car just to cross the street every day. You don’t use a blowtorch to light a match. There are appropriate tools for all tasks, and WordPress is no longer suitable for the most basic of websites.
It doesn’t matter if you believe in climate change and man-made global warming, this is not just about that. I’m talking about professional efficiency, pride and laziness.
Or maybe we simply went insane.
