I'm thinking 12 x 12 or 11'6 x 12'6...11 x 12 at a minimum. We're moving some walls around.
DH can use autocad at work so it's not a big deal for us to move stuff.
Thanks, you're all confirming what I was thinking - I was just starting to wonder after seeing plan after plan after plan with 10 x 10 rooms.
I was talking with our realtor about this (complaining, really), he said it's an absolute hallmark of new construction to have tiny little bedrooms and a huge master suite with room for a lounge room and gym. Maybe people just don't realise how small those 10x10 or 10x11 rooms are when they only see them empty? Or they think of a nursery or office and not a teenager living in them?
I would sacrifice size in one bedroom to get more in the other, or cut out bonus room or flex or dining space. When you're thinking of resale, a 1600 sq ft house is going to appeal to a couple or young family. They're more likely to use one bedroom as an office than a bedroom.
In the houses I've lived in fewer bigger rooms always felt more spacious than more smaller rooms.
