### Get started with large screens

Large screens expand your app development opportunities. The large screens of tablets, foldables, and ChromeOS devices showcase content, facilitate multitasking, and enable user interfaces not possible on small screens.

## Imagine your app on large screens

A more productive productivity app, more engaging media app, more immersive game. Imagine what you can do with the wide open display space of large screens.

## ...with the help of app quality guidelines

[![Depiction of the three tiers of the large screen app quality guidelines.](http://developer.android.com/static/images/guide/topics/large-screens/quality-guidelines/quality_guidelines_header_small.png)](http://developer.android.com/docs/quality-guidelines/large-screen-app-quality)  
To get started with large screen development, follow the *Large screen app quality guidelines*. The guidelines are a comprehensive set of requirements designed to help make your app the best it can be on large screens.  
[Quality guidelines](http://developer.android.com/docs/quality-guidelines/large-screen-app-quality)

### App quality tiers

The quality guidelines are organized into three tiers: *Large screen ready* , *Large screen optimized* , and *Large screen differentiated* . Add large screen capabilities to your app by progressively working through the tiers, starting with Large screen ready. If you have an existing app, use the [quality guideline tests](https://developer.android.com/docs/quality-guidelines/large-screen-app-quality#large_screen_compatibility_tests) to determine the tier your app supports, then implement features tier by tier until your app is uniquely differentiated for large screens.
