Because of improvements in technology and human behaviors web standards change. While, even few years ago the standard width of a website was 800px, nowadays it seems to be not enough pixels in a horizontal direction to show nicely content on the web.
The standard width is driven by a size of screens used by Internet users, and a resolution of those screens.
Let’s see data about some popular websites, and a width of the biggest wrapper of the page:
- YT.com – 972px
- Cnn.com – 1002px
- Facebook – 980px
Another source of the decision about a width of your website should be data collected by Google Analytics which you have probably connected to your site. It shows statistic about a resolution among your users.
According to data from W3School Display Statistics, if you use resolution around 1000px, you will cover more than 96% of Internet users.
