Not saying that there is no problem with the radios, but that particular usage is more confusing than the rest. The distance between the two options, and the added circle for help don't convey any hierarchy.

@Amire80 do you feel a typical usage — like the one in the demos— is equally hard to understand?

@Amire80 This has been changed a while ago to follow the design templates in M101 and there is a small, but maybe decisive sizing issue (too big) of the white inline dot. Are you feeling as strongly when looking at the demos?

Related to this, as part of the research on the new filters for edit review (T162675) we are observing users making use of pagination settings (T162786) in a prototype, which includes radio buttons. We have not observed issues so far, but we'll take a closer look to identify potential sources of confusion around this.

Here's a test case with the dot 2px smaller in each direction (example “Dog” on the RadioSelectInputWidget in contrast to current status quo above.

In :focus state:

I think I know what really bothers me: That the blue circles are considerably larger than the font of the label text.

This looks good. Especially in the case of the focused state helps to clarify the difference between the main element and the focus-related border.

In that case I think we can close this ticket and continue the discussion about T86003: MediaWiki theme: Checkboxes and radios size (original design looks oversized on desktop)
