Hello mrchapel & Welcome!
I agree with at4101. I couldn't have said it better myself.
This is a standard guy's haircut leaving about 1" length on the very top (front) and ending with about 1/4" length buzzed in back, maybe about 1/8" on sides. His sideburns were artfully trimmed around.
And, as was suggested, take the pics with you when you get your cut. A picture is worth a thousand words.
