A standard bank card measures 85.6 mm by 54 mm. The iPhone 12 is about 1.7 times as tall as a card and 1.3 times as wide.
The iPhone 12 has flat aluminum edges. That gives it a squarer profile than the rounded sides of the iPhone 11.
iPhone 12 screen size and resolution
Apple lists the iPhone 12 display as 6.1 inches measured diagonally. The screen has rounded corners, so Apple’s footnote puts the true rectangle diagonal at 6.06 inches.

iPhone 12 vs iPhone 12 Pro size
The iPhone 12 and iPhone 12 Pro have identical height, width and depth. The Pro weighs 27 grams more because it uses a stainless steel frame instead of aluminum.

The iPhone 12 mini is 15.2 mm shorter and 7.3 mm narrower than the iPhone 12. It weighs 27 grams less.
The iPhone 12 Pro Max is the largest model. It stands 14.1 mm taller and 6.6 mm wider than the iPhone 12, and it carries a 6.7-inch screen.

Is the iPhone 12 smaller than the iPhone 11?
Yes. The iPhone 12 is smaller than the iPhone 11 in every dimension, even though both phones have a 6.1-inch screen.
| Model | Height | Width | Depth | Weight | Display type |
|---|---|---|---|---|---|
| iPhone 11 | 150.9 mm | 75.7 mm | 8.3 mm | 194 g | LCD |
| iPhone 12 | 146.7 mm | 71.5 mm | 7.4 mm | 162 g | OLED |
| iPhone 13 | 146.7 mm | 71.5 mm | 7.65 mm | 173 g | OLED |
The iPhone 12 is 4.2 mm shorter, 4.2 mm narrower and 0.9 mm thinner than the iPhone 11. It also weighs 32 grams less.
Apple shrank the body by replacing the iPhone 11’s LCD with an OLED panel. The OLED screen allowed thinner borders around the display.
iPhone 12 vs iPhone 13 size
The iPhone 13 kept the same height and width as the iPhone 12. It is 0.25 mm thicker and 11 grams heavier, and it carries a larger battery.
Do iPhone 12 cases fit other models?
Cases for the iPhone 12 also fit the iPhone 12 Pro, since the two phones share the same body size. Apple sold its own cases labeled for both models.
iPhone 13 cases are a poor fit for the iPhone 12. The iPhone 13 places its two rear cameras diagonally, so the camera cutout sits in a different spot.
The iPhone 12 mini and iPhone 12 Pro Max need their own cases. Their heights and widths differ from the standard iPhone 12.
