If it is the first, then Ian's spot on. I tend to stare at a screen all day, and my vision - what I tend to look at has narrowed up over the years. It used to be that an 85mm lens equalled what I 'saw'. Now, 105mm - sometimes 135mm (yeah, I ought to get out more often).
But if you want the objects in the print in your hand to have the same apparent size as a landscape, Nicholas' comments would be your key.
