I don't think that's too wide. I prefer my scarves to be just a bit wide anyway. Depending on which pattern you are using, the scarf might curl up on itself just a little.
Length would depend on the guy. Practical, busy, no-nonsense types would want a scarf long enough to tuck in, and not much longer.
I agree with the previous poster, I don't think it's too wide and my husband would prefer a shorter scarf- no nonsense. The length may also depend on how cold it gets where the receiver lives. When it's really cold, I like a longer scarf so I can wrap it around a few times.
