I like 210mm (8+") or 240mm (9.5") for a home all purpose gyuto. I understand why some recommend the 270's (10.6") I just find them huge. To each their own. I actually have a pretty spacious kitchen/cooking area, with a boardsmith 22x16" board and I reach for a 210 quite a bit. That's what works for me.
