One marked difference between current tablets is the aspect ratio of their displays. This blog post explores the pros and cons of the different aspect ratios, along with the question whether one of them is best overall.

## The aspect ratios of current tablet displays

 Device Size Normalized aspect ratio Apple iPad mini 768px × 1024px 96 × 128 Apple iPad 1536px × 2048px 96 × 128 Google Nexus 7 800px × 1280px 87.636 × 140.217 Google Nexus 10 1600px × 2560px 87.636 × 140.217 Microsoft Surface 768px × 1366px 83.118 × 147.838 TV 3:4 96 × 128 DVD 9:16 83.138 × 147.802 Anamorphic(movie theaters) 1:2.39 71.704 × 171.372 Letter 8.5in × 11in 97.444 × 126.104 A4 210mm × 297mm 93.212 × 131.828

The last column shows the aspect ratio normalized to an area of 12288 (96 times 128). That is, all areas in that columns are the same, only the sides of the rectangles are different. The formula for the factor n with which the sides have to be multiplied is:

$n=12288width·height$

The rectangles look as follows.

## Is there a perfect aspect ratio?

Current tablets are optimized for different applications:

• The Surface works best for watching movies. Its resolution (between 1365$\frac{1}{3}$ × 768 and 1366 × 768.375) is almost 16:9, the aspect ratio of DVDs and many notebook screens.
