"Set to Frame Width"

YES, please! A feature/option like "fit to composition / width / height" in After Effects would be tremendously helpful with photos and other footage.

Yes. Similar to "set to frame size". Could be called "fill to frame size"

I've found a free extension that allows filling the whole frame: https://julien.chichignoud.com/adobe-premiere-handy-tools

@53580 Herlihy - have a look at the comment from Sir Ivan below. Excalibur does that (and a lot more)

Surprised this is still not yet a feature (or, preferably as suggested, "touch from inside" / "fill frame"). This is basically a Windows 95 wallpaper level of functionality! 😁

In the meantime, is there another way that I can achieve this in Premiere? (E.g. a preset or some kind of script?).

I had thought about, e.g., creating a Photoshop action for batch processing images I use to 2160 height, and then a Premiere preset for scaling them to 50% -- but this is a little messy from my perspective (and I'd prefer to have the performance benefits of working with smaller images / no-higher-than original pixel density where possible).

AE has this for ages. Cmd+Alt+W and Cmd+Alt+G, scales footage to fit height or width of comp. Simple. Please bring this to PR.

Set Full Frame with Crop is all I want.

I had to deal with this on a 1920x1080 timeline where someone had filmed broll all in DCI 4K, which meant it was scaling automatically to 46% instead of 50%.

It is worth noting that "set to frame size" has a bug where one pixel will show around the perimeter. That would need to be fixed for this suggestion to be worthwhile. https://adobe-video.uservoice.com/forums/911233-premiere-pro/suggestions/34818967-set-to-frame-size-is-inaccurate
