Where to keep text and details
The iMac 24″ has no notch. Only the menu bar covers the top 48 pixels at full resolution, so you can use nearly the whole picture.
The Dock still covers part of the bottom edge unless you hide it. Keep a short line of text in the middle and leave the corners for quiet details.

Questions and answers
What size is an iMac 24″ wallpaper?
4480 × 2520 pixels. That is the native resolution of the display, and a wallpaper of exactly this size is shown without any scaling.
Can I use a wallpaper made for another Mac?
It works, but macOS scales or crops it to fit. Fine lines get soft and text near the edges can be cut off. For the sharpest result, make it at 4480 × 2520.
Can the wallpaper on the iMac 24″ switch between light and dark automatically?
Yes. A .heic file can hold a light and a dark image, and macOS shows the one that matches your appearance. The generator makes this file for you. How to set it up.
Why not use the “looks like” resolution from System Settings?
That number is the scaled working area for windows and text. The panel itself has 4480 × 2520 pixels, and that is the size a wallpaper needs to stay sharp.
