Looks like Jay is a little shorter than Phil after all. When I saw Phil in person he looked to be at least as tall as me. I am just a little bit over 5'9" in the morning and usually shrink to 5'8.5" at night. At the time of day I saw Phil I would have been 5'9" or just barely under.
It's hard to say exactly, but I would peg Phil at somewhere between 5'8.5"-5'9.5" depending on the time of day, posture, etc. But it's safe to say that whatever height Phil is, he is slightly taller than Jay.
