People generally want to be able to use their favorite apps on all of their devices and in any context. To meet this expectation, design an adaptable interface by configuring UI elements and layouts to automatically change shape and size on different devices, during multitasking on iPad, in split view, when the screen rotates, and more.

Device Screen Sizes and Orientations

iOS devices have a variety of screen sizes and people can use them in either portrait or landscape orientation. In edge-to-edge devices like iPhone X and iPad Pro, the display has rounded corners that closely match the device’s overall dimensions. Other devices — such as iPhone SE and iPad Air — have a rectangular display.

If your app runs on a specific device, make sure it runs on every screen size for that device. In other words, an iPhone-only app must run on every iPhone screen size and an iPad-only app must run on every iPad screen size.

NOTE All scale factors in the table above are UIKit scale factors, which may differ from native scale factors. For developer guidance, see scale and nativeScale.

To learn how screen resolution impacts your app’s artwork, see Image Size and Resolution.

Auto Layout

Auto Layout is a development tool for constructing adaptive interfaces. Using Auto Layout, you can define rules (known as constraints) that govern the content in your app. For example, you can constrain a button so it’s always horizontally centered and positioned eight points below an image, regardless of the available screen space.

Auto Layout automatically readjusts layouts according to the constraints you specify for certain environmental variations, known as traits. You can set your app to dynamically adapt to a wide range of traits, including:

Different device screen sizes, resolutions, and color gamuts (sRGB/P3)
Different device orientations (portrait/landscape)
Split view
Multitasking modes on iPad
Dynamic Type text-size changes
Internationalization features that are enabled based on locale (left-to-right/right-to-left layout direction, date/time/number formatting, font variation, text length)
System feature availability (3D Touch)

Layout Guides and Safe Areas

A layout guide defines a rectangular region that helps you position, align, and space your content on the screen. The system includes predefined layout guides that make it easy to apply standard margins around content and restrict the width of text for optimal readability. You can also define custom layout guides.

A safe area defines the area within a view that isn’t covered by a navigation bar, tab bar, toolbar, or other views a view controller might provide.

How to get device width and height?

In Objective-C we can get device width and height by using following code :

How can do this in with Swift ?

13 Answers 13

I haven’t tried but it should be..

Swift 4.2

@Houssni ‘s answer is correct, but since we’re talking Swift and this use case will come up often, one could consider extending CGRect similar to this:

Then you can use it like:

If you want to use it in your code. Here you go.

(Swift 3) Keep in mind that most width and height values will be based on device’s current orientation. If you want a consistent value that is not based on rotation and offers results as if you were in a portrait-up rotation, give fixedCoordinateSpace a try:

Exactly like this, tested it also.

Since you’re looking for the device screen size the simplest way is:

While @Adam Smaka’s answer was close, in Swift 3 it is the following:

A UIScreen object defines the properties associated with a hardware-based display. iOS devices have a main screen and zero or more attached screens. Each screen object defines the bounds rectangle for the associated display and other interesting properties

To get Height/width of ur user’s device with swift 3.0

This works great for Xcode 12

height:100% is not 100% after rotating device

I’ve observed some strange behavior that started around iOS 12.2 and continues through iOS 13.x. If you load even a very simple web page into Safari that contains a div with a 100% height, then the result is correct and you get a full-screen div. If you rotate the device to landscape then it resizes and the div still fills the screen. But when you rotate it back to portrait, an empty white area appears at the bottom of the screen, and there doesn’t appear to be a way to make it go away.

I suspect this has to do with the change Apple made around the iOS 12.2 timeframe, where when a phone is rotated to portrait, the URL bar shrinks and the navigation bar is hidden. When this happens, the content area is in effect larger than it was before, but it’s like CSS doesn’t know about it, so a height of 100% represents the height as if the URL bar was larger and the nav bar was present.

This HTML is enough to show the issue:

Viewing that page on an iPhone with iOS 12.2+ will look fine, so rotate to landscape and then rotate back to portrait. A white area will appear at the bottom. I’m told that on larger-style iPhones, this only occurs if it is the only tab open — otherwise, iOS never hides the navigation bar. On my 6s, it happens every time.

Has anybody seen this before? Any ideas for working around it? It is making all of our web apps «scrunch up» after users rotate their devices, with no obvious way to programmatically fix it!

100vh problem with iOS Safari

The web content it’s outside the viewport although we used 100vh (the red opacity box with 100vh text).

The problem you have been receiving after adding the height: 100vh to mobile resolutions. It happens due to the calculation method which Safari and Chrome are using. Mobile devices calc browser viewport as ( top bar + document + bottom bar) = 100vh. I had a hard time with 100vh when the page have to have a section filled the whole screen. After a couple of hours, I’ve found the solutions that I show you.

They are two solutions, the first needs JavaScript and CSS, the second solution required only CSS.

1. JS & CSS solution

Let’s get started first with the JS file:

appHeight function has sets new style property var(` — app-height`) including current window height, — app-height it is necessary for next steps.

In the previous step I’ve created the reference — app-height, wrapping in the var() I’ve received CSS variable var( — app-height). This variable is allowed to read values created by JS.

2. CSS solution (not recommend)
The last, but not the least solution is ` — webkit-fill-available`, this solution works only on Apple devices, it won’t solve the problem on Android devices. I don’t recommend this solution, but it’s worth showing.

Thank you for your attention! I’ll appreciate your feedback.

Apple iPhone 12 will be launched in October 2020.
Apple iPhone 12 have iOS 14.1

Screen Dimensions

Apple iPhone 12 screen size is 6.1 inch with

86.0% body ratio of actual device size. Physical dimensions for Apple iPhone 12 device is 5.78 x 2.81 x 0.29 INCH or ( 146.7 x 71.5 x 7.4 MM).

Displaying of Units are in this order «Height x Width x Thickness»

Screen Pixel Density and CSS Pixel Ratio

«Pixel» is smallest unit/element of any display.

The total number of pixels that fit into an inch is referred to as «Screen Density» or «Pixel Density» and it measured as «Pixels Per Inch».
Pixel Desnsity have limits to display Pixels Per Inch depends on different screen sizes. When number of pixels per inch increases than it’s screen-size limit, the Display resolution will increase but actual device width/height in pixels remain same. Actual device pixels are known as Device Independent Pixels or CSS Pixel Ratio.

Apple iPhone 12 resolution is 1170 x 2532 PX with

460 pixel desnsity.
Apple iPhone 12 viewport size is 390 x 844 PX with

153 actual pixel density, which means it have 3 xxhdpi display pixel density.

Screen Resolution and Viewport

The sum of pixels which are displaying on a device is called as «Screen Resolution». and sum of actual pixels of any device is reffered to as «Viewport».

Apple iPhone 12 have 6.1″ physical screen size and its resolution is about 1170 x 2532 Pixels with approximately 460 PPI pixel density. Apple iPhone 12 has viewport size 390 x 844 Pixels and its pixel ratio is about 3 .
