How to read this table

Every Apple display has two sizes: the one your layout code works in, measured in points, and the one the hardware actually has, measured in pixels. The table lists both for each device, newest first, along with the physical measurements that connect them.

Logical Width and Logical Height (pt)

The size of the screen in points — the unit UIKit and SwiftUI measure in. This is the coordinate space you write a layout against.

Physical Width and Physical Height (px)

The pixel dimensions of the panel. These are the logical dimensions multiplied by the scale factor.

Diagonal (in)

The corner-to-corner measurement of the screen in inches, as Apple describes it.

PPI (px/in)

Pixel density, in pixels per inch. A higher number means a finer image at the same physical size.

Aspect Ratio

The proportion of width to height. Ratios that do not reduce to whole numbers are marked with a tilde, as in ~19.5:9.

Scale Factor

How many pixels the device draws per point along each axis, written 1x, 2x or 3x.

Release Date

The date the device went on sale.

Frequently asked questions

What is the difference between logical points and physical pixels?

A point is the unit your layout code works in; a pixel is a dot on the display. The scale factor relates them. An iPhone 17 Pro is 402 × 874 pt and 1206 × 2622 px, because it renders three pixels per point. Two devices can share a point size and differ in pixels, which is why a layout written in points carries across the lineup.

What does @2x or @3x mean?

It is the scale factor. At @2x one point is a 2 × 2 block of pixels; at @3x it is a 3 × 3 block. The original iPhone through the iPhone 3GS were @1x, as were the first two iPads. Most displays since are @2x, and every iPhone released in the last several years is @3x. Image assets are supplied at matching densities so artwork stays sharp.

How do I convert points to pixels?

Multiply by the scale factor: 402 pt at 3x is 1206 px. Divide to go the other way. The Physical Width and Physical Height columns are already the result of that multiplication, so either unit can be read straight off the table.

What does PPI mean here?

Pixels per inch — how densely the pixels are packed. The densest displays in this table are on the iPhone 12 mini and iPhone 13 mini at 476 PPI. The original iPhone was 163 PPI.

Which iPhone screen size should I design for?

The iPhones released in the last two years cover four single-screen logical sizes: 390 × 844 pt on the iPhone 17e, 402 × 874 pt on the iPhone 17, 17 Pro and 18 Pro, 420 × 912 pt on the iPhone Air, and 440 × 956 pt on the iPhone 17 Pro Max and 18 Pro Max. The iPhone Duo adds 626 × 890 pt inside and 466 × 678 pt outside. Design a layout that adapts across that range rather than targeting one size.

Which Apple device has the most pixels?

The 13-inch iPad Pro, at 2064 × 2752 px — about 5.7 million pixels. Among iPhones it is the inner screen of the iPhone Duo at 1878 × 2670 px, followed by the iPhone 17 Pro Max and iPhone 18 Pro Max at 1320 × 2868 px.

Why does the iPhone Duo take up two rows?

Because it has two screens with different specifications. The inner screen is 7.58 inches at 626 × 890 pt (1878 × 2670 px, 430 PPI) and the outer screen is 5.36 inches at 466 × 678 pt (1398 × 2034 px, 460 PPI). Both render at @3x.

Can I download this data?

Yes. The PDF and CSV buttons above the table export whatever is currently filtered and sorted, using the same columns and units shown here.
