Almost same weight as 8 and 8a - FWIW I have 8, and the size and weight are very comfy, as a previous 3a owner (I "downgraded" from Pixel 6 which was too big and too heavy to fit in one hand and in the pocket, though I actually gotten used to it at home as a "tablet"). Using Spigen Liquid Air case.
Weight: 185,9 g or: 6.6 oz
A bit lighter than the previous versions, though I do miss the days where tha 4a was just around 145g or so.
