Large screens (2560x1600, 2048x1536, 1920x1200) width in dp

Question

Information I found: 320dp: regular phone screen (240x320 ldpi, 320x480 mdpi, 480x800 hdpi, etc.). 480dp: Tweener tablet such as Streak (480x800 mdpi). 600dp: 7-inch tablet (600x1024 mdpi). 720dp: 10-inch tablet (720x1280 mdpi, 800x1280 mdpi, etc.).

But its appearance since 2011. Now is the year 2014, and there are 2048x1536, 2560x1600, 1920x1200 tablets and phones. Are they still 720dp wide or does it also exist 800dp, 1024dp or whatever? This remains unclear to me, because all the discussions that I found relate to 2011, when such devices were not on the market. If it depends on the manufacturer, can you share information on the Sony Xperia Z tablet and the width of the Samsung TabPro 10.1 in dp format?

Answer 1

It also depends on density, not just resolution.

Here is the equivalent for dp for pixels depending on the density:

• mdpi: 1 dp = 1 pixel
• hdpi: 1 dp = 1.5 pixels
• xhdpi: 1 dp = 2 pixels
• xxhdpi: 1 dp = 2.5 pixels

So yes, a device with a resolution of 2560x1600 in xhdpi has a width of 1530 dB.
