What is the maximum screen size for a phablet that you would consider buying?

Title. Basically, we have quite a few phablets today, and I'm wondering what you guys think is the maximum screen size that is marketable. I'll give a few ranges for you guys to choose from.

5"<x<5.5"

5.5"<x<5.75"

5.75"<x<6"

6"<x<6.25"

6.25"<x<6.5"

6.5"<x<6.75"

6.75"<x<7"

Answer away.
