According to to StatCounter, which tracks statistics on over 2 million websites globally, the most popular desktop screen resolutions in the U.S. in 2018 were as follows.
| Desktop Screen Resolution | Percentage Market Share |
|---|---|
| 1920×1080 | 19.45% |
| 1366×768 | 16.51% |
| 1440×900 | 8.83% |
| 1536×864 | 6.13% |
| 1600×900 | 5.14% |
Now, you’ll notice the shares above do not equal 100%. Well that’s because mobile phone use continues to increase…
| Desktop Vs Mobile Vs Tablet | Percentage Market Share |
|---|---|
| Desktop | 52.27% |
| Mobile | 39.86% |
| Tablet | 7.87% |
Of course, all of these numbers vary widely by demographic. For example, a retail restaurant will typically serve more mobile visitors than a heavy e-commerce site. Last year, I conducted a Site Audit for a data-driven website for scientists where 98% of visitors used desktop computers to access the information. Obviously, their Return On Investment for a mobile-responsive site upgrade would be minimal.
