Curious how the OnePlus 15 stacks up against other phones in terms of size and weight? Below, we’ve rounded up the dimensions and weight of the OnePlus 15, along with comparisons against its predecessors and today’s top flagships.
While the OnePlus 15 doesn’t come with any drastic changes to its size over the previous model, it does introduce a few notable differences in proportions and design. With its flat display, larger battery, and sturdier metal frame, the OnePlus 15 feels more solid in the hand while keeping roughly the same footprint as before.
OnePlus 15 vs Galaxy S25 Ultra vs iPhone 17 Pro Max vs Pixel 10 Pro XL
Here, the OnePlus 15 finds itself right between the major flagships. It’s slightly shorter and narrower than the Galaxy S25 Ultra and the iPhone 17 Pro Max, but it is very similar in size to the Pixel 10 Pro XL. At 7.44 oz (211 g), it’s the lightest of the group by a noticeable margin, with the iPhone and Pixel crossing the 8 oz mark, and the Galaxy not that far behind it. That makes the OnePlus 15 one of the more compact large-screen flagships of the year.
OnePlus 15 vs OnePlus 13 vs OnePlus 12 vs OnePlus 11
The OnePlus 15 measures 6.35 x 3.02 x 0.32 inches (161.4 x 76.7 x 8.1 mm) and weighs 7.44 oz (211 g). Compared to the OnePlus 13, the new model is slightly shorter and a touch thinner, while maintaining nearly the same width. The overall footprint has subtly decreased since the OnePlus 12 and 11, both of which were taller and heavier.What’s interesting here is how OnePlus has gradually refined its design with every generation. The OnePlus 15 feels denser and more balanced thanks to the new metal chassis and larger battery, yet it’s still lighter than the OnePlus 12. The move to a fully flat display and thinner bezels also gives it a slightly more compact appearance when viewed from the front.
OnePlus 15 vs Vivo X300 Pro vs Oppo Find 9X Pro
When compared with the Vivo X300 Pro and Honor 9X Pro, the OnePlus 15 lands right in the middle in both size and weight. It’s slightly shorter and thinner than both, though the differences are minor. The Vivo is the heaviest at 7.97 oz (226 g), while the OnePlus sits just below it at 7.44 oz (211 g).All three are close in height, hovering around 6.35–6.42 inches tall.
OnePlus 15 vs Galaxy S26 Edge vs iPhone Air
Against the new wave of thin, premium phones, the OnePlus 15 shows its flagship size more clearly. It’s both taller and wider than the Galaxy S26 Edge and the iPhone Air, and considerably heavier at 7.44 oz (211 g) versus the iPhone’s 5.82 oz (165 g) and the Galaxy’s 5.75 oz (163 g).
