A size comparison of the upcoming OnePlus 15 has surfaced.

Want to know how the OnePlus 15 compares to other phones with regard to size and weight? The OnePlus 15's dimensions and weight are listed below, along with comparisons to earlier models and current top-tier phones.

While the OnePlus 15's size hasn't changed significantly from the previous version, there are some significant changes to its proportions and design. The OnePlus 15 has a flat display, a bigger battery, and a more durable metal frame, giving it a more substantial feel while maintaining about the same size as before.

The OnePlus 15 is positioned between the top-tier smartphones. It is a little smaller in height and width than the Galaxy S25 Ultra and the iPhone 17 Pro Max, but it is about the same size as the Pixel 10 Pro XL. It is also the lightest of the group at 7.44 oz (211 g), with the iPhone and Pixel exceeding 8 oz and the Galaxy closely behind. This makes the OnePlus 15 among the most compact large-screen flagships available this year.

The OnePlus 15 is 6.35 x 3.02 x 0.32 inches (161.4 x 76.7 x 8.1 mm) in dimension and 7.44 oz (211 g) in weight. Compared to the OnePlus 13, the new phone is slightly shorter and thinner, but it has almost the same width. The overall size has marginally decreased from the OnePlus 12 and 11, both of which were taller and heavier.

It is interesting to note how OnePlus has improved its design with each new generation. The OnePlus 15 feels more substantial and balanced because of the new metal frame and bigger battery, yet it is still lighter than the OnePlus 12. The switch to a completely flat display and smaller bezels also gives it a somewhat more compact appearance when viewed from the front.

The OnePlus 15 is in the center of the size and weight range when compared to the Vivo X300 Pro and Honor 9X Pro. Although the differences are minor, it is somewhat shorter and thinner than both. The Vivo weighs the most at 7.97 oz (226 g), while the OnePlus weighs slightly less at 7.44 oz (211 g).

All three are about the same height, measuring between 6.35 and 6.42 inches.

Compared to the new generation of thin, premium smartphones, the flagship size of the OnePlus 15 is more evident. At 7.44 oz (211 g), it is taller and wider than the Galaxy S26 Edge and the iPhone Air, and it is noticeably heavier than the iPhone (5.82 oz or 165 g) and the Galaxy (5.75 oz or 163 g).
