In context

How big is iPhone SE (3rd generation), really?

Of the 34 iPhones on this site, iPhone SE (3rd generation) is the 3rd smallest by the size of its front (138.4 × 67.3 mm), the 3rd lightest at 144 g, and has the 33rd largest screen at 4.7 inches. That puts it among the easier iPhones to use with one hand.

Its 4.7-inch display is about 58.5 × 104.1 mm (worked out from the diagonal and its 1334 × 750 pixel grid), so the screen covers roughly 65% of the front. The deep bands above and below the screen hold the Home button with Touch ID and the front camera, which is why that share is far lower than on Face ID iPhones. At 326 pixels per inch, text looks sharp at arm’s length, though a little softer than on newer models.

Against iPhone SE (2nd generation) (2020), the model it followed, it is 4 g lighter, the chip moves from A13 Bionic to A15 Bionic, and Apple's video playback rating rises from 13 to 15 hours.

iPhone SE (2nd generation) shares its height and width to within 0.3 mm, so in the hand they feel almost the same size, even if cases are cut differently around the cameras and buttons.
