As is tradition, we are first comparing the OnePlus 12 with its relatives, and as it is immediately noticed from the numbers presented above, the latest flagship from OnePlus is a bit larger in all of its dimensions when compared to the last two generations. Most noticeable here is the increase in thickness, as well as the weight.

What's interesting, however, is that it is only 1 mm thinner than a closed OnePlus Open, which only makes the foldable even more impressive. That being said, it is still about 20g leighter in comparison, which is to be expected.

Now, when placed next to other "plus-sized" phones that don't have titles including words like "Pro" and "Ultra", the OnePlus 12 continues to be a hefty piece of tech in comparison. For starters, it is a good 20g heavier, and considerably thicker, especially next to the Galaxy S24+ and iPhone 15 Plus.

Only when we place the OnePlus 12 next to the most high-end phones currently being sold, do we finally see it competing in its own weight class. It mostly weighs the same, and has very similar dimensions as the rest, but still manages to stand out with its thickness. Most likely, one of the main reasons for this abnormally thicker body is the humongous 5,400mAh battery that OnePlus has placed inside.
