Nowadays most computer users (Windows Operating Systems) has their monitors' display settings set at higher than 800px X 600px, for examples 1024px X 768px hence making things looks smaller but shows a wider view of the whole webpage or any working documents.
15inch to 17inch monitors gives a better preview in 1024 x 768px.

my own case, using a hp p1120 (21inch) display settings set at 1280X1024px!

Check and see the difference of these two settings.


Display Settings set at 800px X 600px


Display Settings set at 1280px X 1024px

extra informations.
Any 21inches monitors and above could actually show an exact view of a piece of A4 size paper on its screen, viewing 100% exact size with settings of 1280px X 1024px. If the settings is pshed higher to 1600px X 1200px, then 100% viewing would actually show the A4 smaller than the real paper size when placing a piece of A4 paper on the monitor screen.

Any webpage designed must be able to be viewable by most settings so there are normally set at the minimum display setings of 800px X 600px, which is also known as the basic webpage size. If a 800x600 shows the content nicely arranged, other higher display settings monitor would encounter no problems viewing them besides having them in smaller views.

I sincerely hope that these could be of help to you my friend.
