WordPress directory sizes
Directory sizes show how much disk space the files of your WordPress site take up, folder by folder: WordPress itself, the uploads, the themes, the plugins and the fonts. WordPress’s Site Health screen shows the same breakdown.
Why it matters
Section titled “Why it matters”The sizes show where your storage goes. They matter for the limits of your hosting plan, for how long backups take and how large they are, and for moving the site to another server.
They don’t say anything about how fast pages are. A visitor only downloads the files a page uses, not the folder they live in. The database is counted separately; see Database size and tables.
Each folder counts once: the size given for WordPress itself doesn’t include the uploads, themes and plugins listed next to it.
What influences it
Section titled “What influences it”WordPress: The uploads folder is usually the largest, because WordPress stores several copies of every image; see Media Library size. Backup plugins that keep their archives inside the uploads folder, caches written to disk and logs can make it grow quickly. Inactive plugins and unused themes still take up space in their folders.
Server: Some setups store media on a separate storage service; the files there don’t count toward the local folders.
In Permo
Section titled “In Permo”The Directory sizes section is in System info, tab Content. Permo measures only when you
select Measure directory sizes, because it reads every file in the WordPress folders, which
takes a while on large sites. The table lists Uploads (media files with all image sizes),
Plugins, WordPress (without wp-content), Database and Themes, and the Total,
which adds up the rows. Other folders in wp-content, such as caches or language files, aren’t
included.
The sizes give context; Permo doesn’t rate them. If the measurement doesn’t finish within its time limit on a very large site, the section says so, and the previous result stays.
