Why Material 3 Icon/Button sizes are abnormally huge by default?

I recently learnt briefly about material 3 in compose & implemented it in the current app I'm building for learning purposes (google calendar clone). In google calendar app, which I guess follows material 2, the size of buttons and switches seem normal. But with material 3 in my app, everything seems abnormally huge. Is it how material 3 is supposed to be? I chose to make a clone because I wanted a good UI reference. I guess I shouldn't have used material 3 for this app. What are your thoughts on the default sizes in M2 VS M3?

I've attached the same screen I tried to replicate from google calendar app.

I tried reducing the padding with contentPadding parameter in Button/TextButton composables. But it didn't work outm

Yes there are difference in size and shape of both M2 and M3 design, also as you can see the design of switch, both looks quite different.

Google also recommends not to migrate from M2 to M3 compose unless you have migrate your app design M2 to M3.
