A guide of standard practices, official guidelines(HIG) for designing iOS/iPadOS applications.

This cheat sheet is mainly an attempt to keep track of wide variety of devices and their design constraints that are updated regularly.

App Icons

Let’s pick the guidelines directly from the latest(11.3.1) Xcode’s storyboard.

Type Size Supported iOS Version Assets
iPhone Notification 20pt iOS 7-13 2x, 3x
iPhone Settings 29pt iOS 7-13 2x, 3x
iPhone Spotlight 40pt iOS 7-13 2x, 3x
iPhone App icon 60pt iOS 7-13 2x, 3x
iPad notifications 20pt iOS 7-13 1x, 2x
iPad Settings 29pt iOS 7-13 1x, 2x
iPad Spotlight 40pt iOS 7-13 1x, 2x
iPad App icon 76pt iOS 7-13 1x, 2x
iPad Pro (12.9”) App icon 83.5pt iOS 9-13 2x
App Store 1024pt All versions 1x

Common Layout Guidelines

Status Bar:

A status bar always extends to full width of the device. However, since the introduction of iPhones with notches, status bar was redesigned to facilitate the notch design.

Note: Don’t replace systemwide status bar with a custom one.

Available styles:

  • Light (black icons on a white background)
  • Dark (white icons on a black background)
Device Status Bar Height
iPhone with bezel 20pt
iPhone with notch 44pt
iPad Pro 24pt
iPad with bezel 20pt

A navigation bar is typically placed right below the status bar on iOS designs. Unlike status bar, you can customize this or adopt a different approach to navigation in your designs.

A new navigation bar style with large title was made available from iOS 11 onwards.

Following are the height values (excluding status bar height) for different states of navigation bar.

Navigation State Height
Default navigation bar (portrait) 44pt
Large title navigation bar 44pt + 52pt
Navigation bar on iPhone (landscape) 32pt
iPad (iOS 12+) 50pt
Large title navigation bar on iPad (iOS 12+) 50pt + 52pt

A search bar can be displayed alone, or in a navigation bar or content view.

And, the dimensions of search bar remain same in all the cases unless we decide to use an additional feature – a label further explaining functionality of search bar.

Search Bar Type Height
Search bar without introductory text 51pt
Search bar with introductory text 82pt
Tab Bar:

A tab bar is another type of approach to navigation inside the app.

Note: Use Tab Bars strictly for navigation purpose only. Check Toolbars for other purposes.

After Apple removed the physical home button and introduced a home indicator bar at the bottom, consider home indicator height in your designs.
However, as a developer, you might want to read about Safe Area in Autolayout to avoid overlapping of home indicator over your app’s content.

Tab Bar Type Height
Tab Bar without home indicator 49pt
Tab Bar with home indicator 49pt + 34pt
Tab Bar without home indicator iOS 12+ (iPad) 50pt

Iconography

With iOS 13, Apple released SF Symbols to match the new San Francisco system font. If you need a symbol that isn’t provided by SF Symbols, you can create your own.
