16:10
16:10, also known as 8:5, is an aspect ratio mostly used for computer displays and tablet computers. The width of the display is 1.6 times its height. This ratio is close to the golden ratio "" which is approximately 1.618.
LCD computer displays using the 16:10 ratio started to appear in the mass market from 2003. By 2008 16:10 had become the most common aspect ratio for LCD monitors and laptop displays. Since 2010, however, 16:9 has become the mainstream standard, driven by the 1080p standard for high definition television and lower manufacturing costs.
Until about 2003, most computer monitors had a 4:3 aspect ratio and some had 5:4. Between 2003 and 2006, monitors with 16:10 aspect ratios became commonly available, first in laptops and later also in standalone monitors. Such displays were considered to be better suited for productive uses such as word processing and computer-aided design.
In 2005–2008, 16:10 overtook 4:3 as the most sold aspect ratio for LCD monitors. At the time, 16:10 also had 90% of the notebook market and was the most commonly used aspect ratio for laptops. However, 16:10 had a short reign as the most common aspect ratio.
Around 2008–2010, there was a rapid shift by computer display manufacturers to the 16:9 aspect ratio and by 2011 16:10 had almost disappeared from new mass market products. According to Net Applications, by October 2012 the market share of 16:10 displays had dropped to less than 23 percent.
