Clocking in at the breathtaking 0.25" (6.4mm) girth, the Xperia Z2 Tablet is the slimmest tablet out there, almost as thick as its microUSB port. It is also the lightest of them 10" slates, weighing only 15 ounces (426g) for the Wi-Fi model, and 15.5 ounces (439g) for LTE/3G model. For comparison, the Tablet Z predecessor is 6.9mm thin, and weighs 17.46 oz (495 g), while the venerable iPad Air is 7.5 mm, and with 16.86 oz (478 g) of weight, respectively.
Couple the compact and feathery chassis with the IP58 certification, and the Z2 Tablet becomes one of the most well-engineered mobile devices out there. You can dunk it in up to 5 feet (1.5m) of water for more than an hour, and it won't skip a beat. Just make sure the protective port flaps are firmly closed when you lie in the bathtub, binge-watching Game of Thrones, or indulging in some other geeky pleasure.
Arriving with a just 0.26" (6.6mm) thin chassis, and 10.51 oz (298 g) of weight, the first high-res Super AMOLED 8-incher is the most mobile tablet out there, as it weighs as much as a Nexus 7
, and is way slimmer, not to mention much more powerful, and with the highest pixel density of them all, too.
The larger of the two tablets in Samsung's new S line, Galaxy Tab S 10.5, is also just 0.26" (6.6mm) thin, and it weighs 16.47 oz (467 g), making it one of the most compact and light 10-inchers out there. It sports the same 1600x2560 resolution as its 8.4 counterpart, and the same Exynos 5 Octa processor, meaning that it is also the most decked out of them 10-inchers, too.
The fourth place in this category is again occupied by a Sony tablet - the Xperia Tablet Z is breathtakingly thin at 0.27" (6.9mm), which is pretty amazing, and also one of the lightest 10-inchers out there. When you add its waterproof certification, we can only bow again before Sony's marvel of engineering.
Apple's first foray into the smaller tablet niche is a really thin 0.28" (7.2 mm) slate crafted out of aluminum, but that doesn't preclude it from ranking second in our "world's thinnest" competition, a venerable tribute to Jony Ive's design team.
Sixth place goes to Samsung's 8-incher in the TabPRO series, only because it is made out of plastic. Otherwise with 7.2 mm it is as thin as the original aluminum iPad mini, while bearing the greatest pixel density on a tablet - 359ppi - all achieved with a regular RGB pixel matrix, no PenTile shenanigans
like on the Tab S 8.4.
Samsung has obviously managed to slim down its TabPRO line to the extent that we find another representative - the Galaxy TabPRO 10.1 - climbing up in the top ten of the world's thinnest tablets, with its 0.29" (7.3mm) girth. With the same monster screen resolution as the 8-incher, and lighter than an iPad Air, the new 10" slate from Samsung has certainly earned its place on the catwalk.
Samsung logs another serious competitor here, with the 0.29" (7.4mm) thin Galaxy Tab 3 8-inch, which is still in play this year. Just a hair thicker than the iPad mini, it is also pretty light, since the housing is entirely made out of plastic.
Sir Jony Ive is at it again with one of the lightest 10-inchers out there, which on top of that sports a significantly slimmed down 0.3" (7.5mm) waistline, an airy iPad indeed.
The new Apple iPad mini 2 with Retina Display has actually thickened a bit to 0.3" (7.5mm) in comparison with the 7.2mm original mini, but Apple has a good reason for this, as it managed to cram 326ppi pixel density in a humble 8-incher with the 2048x1356 pixels display.
The Amazon Kindle Fire HDX 8.9 tablet is a hardware beast featuring a 8.9'' display with 2560x1600 resolution, or 339 ppi, but it is also very thin at just 0.31" (7.8mm).
The Samsung Galaxy Note 10.1 (2014 Edition) is is also one of the thinnest out there at 0.31" (7.9mm), despite sporting an S Pen stylus silo, and being a powerful 10-inch tablet with a high-resolution display.
Another sub-8mm slate, the 10" addition to last year's Galaxy Tab trio is 0.31" (7.95 mm) high, while the quirky thing about this Android 4.2 Jelly Bean slate is that it is powered by a dual-core Intel Atom processor.
The last, but definitely not the least member of the sub-8mm tablet club is the venerable Galaxy Note 8.0, which, as the name suggests, is a member of the stylus-wielding line of Samsung. Despite the S Pen silo and the digitizer coat, Samsung managed to keep the thickness at 0.31" (7.95 mm) only, securing it a place at the thinnest tablets round table.
The comparatively thin design of this one doesn't really translate to better portability, as we are dealing with Samsung's largest tablet, after all. The 12-incher still clocks in under 8mm, at 0.31" (7.95 mm), so we ought to include it in the rankings for that feat alone.
Despite the s Pen stylus silo, and the extra digitizer and functionality that come with it, Samsung's largest "productivity" tablet sneajs just under the 8mm mark, at 0.31" (7.95 mm), but, again, the notion of mobility here is quite the stretch, as we have a 12" display diagonal, and 26.56 oz (753 g) of weight.
