Small phones with custom ROM support

Here are some resources for finding compact phones w/ custom ROMs:

• The official Lineage devices page The search tool lets you filter phones by desired screen size (and other features!
• Hackable Phones Includes a section on the best compact phones, and lets you search by size

Inspired by this post: https://lemmy.world/post/6597113

At this point I'm not even picky about which custom ROM I run.What I'm looking for is a phone that has a very small form factor and there's any custom ROM that officially supports it.

Ideally, with a 3-4" screenMust be <5"Must be officially supported. (for unsupported builds, I know of a few options already)

Are there any? Thanks for any suggestions or help!
