Screen size/ Resolution relating to objects

I'm not sure how I came about wondering this but here goes:

If you have two different displays that are different sizes- say 20in and 23in- but have equal resolution, will there actually be more room for objects on the bigger display, or will the objects themselves merely appear larger?

This is sort of out of the blue, and if I didn't ask the question clearly, please let me know.

Thanks for your input,

Vito

The objects will just appear larger.

thanks!
