Compared to the current top-selling smartphone, the iPhone 5s, the One is slightly thicker at 8.9 mm (vs. 7.6 mm) and significantly taller at 152.9 mm (vs. 123.8 mm).

While this isn't quite a phablet, reviewers are saying this One's a tad big for single-hand use. Unless, of course, you're the Hulk.
