knowing whats the most popular screen size on the web is important when trying to make a new wallpaper website. you want to know what size or how big the width of your site should be. before in the old days the most popular windows size was 800x600 with windows 09, but ever since windows xp came out it jumped the resolution to 1024x768. i remember two years agon, it was:

800x600
1024x768
1280x1024
1600x1200


i have a laptop and i can say that the laptops now is 1280x800

as time goes, so the screen resolutions are going to get bigger, the next size will have to be 1280x1024 so if you are looking in the future, make sure you create your website design with the current trends on the web
