The tablet screen size trend is different than smartphones. With smartphones, we see a clear trend that bigger is better – with 59% of the market over 5 inches in diagonal screen size.
Two Tablet Groups: Full Size and Mini
Two screen sizes segments clearly emerge from the tablet group:
1) full-size, larger tablets (over 9″ diagonal screen size), and
2) smaller “mini” tablets (less than 9″ diagonal screen size).
The full size segment is the largest market. In particular, the full-size 9.5 to 10” segment has grown from 46.6% in 2017 to 53.6% in 2017 Q2. The largest sizes – over 11″ – have not grown. In fact, despite Apple iPad’s power in the market, the larger iPad Pro versions do not seem to have gained much market share.
Mini is Now Slightly Larger
Back in 2014, the 7-7.5″ was the largest portion of Mini tablet market. Now in 2017, the smaller “mini” segment has shifted away from the 7 to 7.5” size and is predominated by the 7.5 to 8” size. The 7.5 to 8” segment holds 31.8% of the traffic in 2017 Q2.
Usage of the Full size and Mini markets is also interesting. Read more about the prevalence of portrait vs. landscape orientation here.
