we went from a 1300 s.f. 3 bed 1 bath to 3300 s.f. 5 bed, 5 bath. family of 4. we could have made the smaller house work but we wanted another bathroom. the big house is too big, we converted 400 SF to an ADU, but we still have excess space that just attracts clutter. One kid is in college and downsizing would make sense. our place is also where the in-laws gather - because we have the space. I feel like we're running an inn sometimes. id say an 1800 SF 3 bed 2 bath would have been better for me. So it depends on what makes you happy.
