Samsung S22 - 146 x 70.6 x 7.6 mm
Zenfone 8 - 148 x 68.5 x 8.9 mm (could be higher thanks to narrower body)
Xiaomi 12X - 152.7 x 69.9 x 8.2 mm
Samsung S21 - 151.7 x 71.2 x 7.9 mm
Sony doesn't produce phones, but remote controls. Their software is nice clean, but their camera is pretty bad, might as well buy Zenfone 8 if you don't mind camera.
I imagine few who have used one would ever be able to say this with a straight face. I never met an iPhone user who believed me when I told them all the photos I was showing them were taken with an Xperia XZc (1 and 2, respectively) and that's with every single one of them. There may be half a dozen compact smartphones that really compare to the XZ2c. Sony just gave up on them because the herd loves their phablets so much.
I am also a current owner of the Zenphone 8 and its camera is also decent. If it's really important that you be able to snap the best photos possible, though, they've been developing these discrete camera things for over a century (and the best of them will likely continue to outperform any general purpose device for the foreseeable future).

There's really nothing small about any of the Androids.
