Find out in this tutorial how to use custom image sizes in WordPress image and gallery block using code.
In the previous tutorial you saw how to find out all the image sizes that a WordPress installation has.
But you probably noticed that, of all those sizes, only a few of them are available when you use the image or gallery block.
Usually only 3 are shown:
- Thumbnail
- Medium
- Large
But you may be interested in displaying some of the other sizes as well, even one that you have custom registered.
That’s why with this tutorial you are going to get a custom image size to appear in the dropdown of the WordPress image and gallery blocks as well.
Let’s take a look at it:

Also, you can give any name you want to each of the sizes. Instead of “GB Grid Square” you can call it “Genesis Blocks Square” or whatever you prefer. 😉
