Мне нужно, чтобы Radio () было не меньше QLabel. И он вел себя почти так, как если бы QLabel был подключен к макету, находясь внутри QWidget с сохраненным полем и отступом.

Я пытался использовать setMinimumSize ( ) но QLabel всегда 30X100, пока вы не укажете размер вручную. Но постоянно вычислять поля margin, padding, font-size, border и другие свойства qss слишком неудобно.
Это должно работать примерно так

Но без постоянной записи self.setMinimumSize (QSize (140, 34)) руководство
