In context

How big is iPhone SE (2nd generation), really?

Of the 34 iPhones on this site, iPhone SE (2nd generation) is the 4th smallest by the size of its front (138.4 × 67.3 mm), the 4th lightest at 148 g, and has the smallest 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.

iPhone SE (3rd 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.
