Prop sizes

I just got a os 50sx engine. When I was reading the recomended prop sizes it dawned on me that there is no compensation for altitude. Maybe this is not a concern and I have to much time on my hands to think about flying instead of flying. What do you guys think?

I guess a clearer way of stating my question would be: If a given engine was turning a certain size prop at sea level would you need to change the prop size at 1400m above sea level to provide the same load to the engine and the same thrust or are these changes insignificant.
