What the author says it does
This plugin lets you create custom image sizes for your site. Override your theme sizes directly on the Media settings page, regenerate thumbnails, and copy add_image_size PHP for your theme.
ℹ️ Simple Image Sizes, a Mediapapa product
Simple Image Sizes will always remain free. It is actively maintained by me (Nicolas Juen). I’m also building Mediapapa, a complementary plugin focused on understanding and organizing your media library. More on these changes
Features
- Insert images in posts at the right size using your custom sizes.
- Control whether each size appears in the “Insert media” size dropdown.
- Regenerate thumbnails in bulk from Settings → Media, and pick which sizes to rebuild.
- Copy generated add_image_size PHP for your theme when you want to keep sizes and deactivate the plugin.
- Regenerate from the Media library: one file at a time or with list bulk actions.
- Regenerate from a single attachment’s edit screen.
- Approximate end time and clearer feedback while bulk regeneration runs.

Questions the author answers
Where can I add image sizes?
Go to Settings → Media, then you can add an image size. You have to add a unique custom name without any spaces or special chars.
The best is to use something like my-custom-size.
Then you have several fields for configuring the image size, the width, the height, cropping.
And then you can choose if the image is displayed on the media insertion or not ( this will be displayed on the dropdown list ).
Who maintains this plugin?
Nicolas Juen, the original author, continues to lead maintenance together with the Mediapapa Team.
How does Simple Image Sizes relate to Mediapapa?
Simple Image Sizes focuses on creating and regenerating image sizes. Mediapapa focuses on understanding and organizing your media library (usage, cleanup, duplicates, and related workflows).

Where this page's numbers come from
Read from the WordPress.org plugin API on , when WordPress 7.1.4 was the current release. WordPress.org rounds active installs into buckets. These are the directory's figures, not my verdict, and I haven't tested this plugin.
