The Pixel 9-11 Pros are all smaller than the Pixel 6-8 Pros. "Pro" initially meant "larger and better" but more recently just "better" and if you want a huge phone you buy the Pro XL.
I was caught by surprise on this. I have P8Pro and while its fine, I was just kind of curious about how much of an upgrade it would be to the 11Pro, especially since I haven't really given the last two years releases any attention.
But the P11 Pro is now 6.3" and the P8 Pro was 6.7" meaning you have to go up to the P11 Pro XL (for another $200) for the same size. Well technically its 6.8" vs 6.7 but I feel this is just a form of shrinkflation and enshittification. Literally no other improvements on the XL as far as I can tell from the specs, not even a larger battery.
While I certainly don't need a bigger phone, I would be pissed if I just hit the buy button and what came out of the box was half an inch smaller.
Portability is a feature. 6.7" have are so big and heavy they are annoying to carry on many pants or while doing many physical activities.
I find my 6.1" Pixel 6a way too big already. I really loved the size of the Samsung Galaxy S6 that preceded it, I think it was the sweet spot at 5.1", large enough to read text, navigate on a map or watch a video while still being pocketable and light.
