Viewport is a module for responding to changes in the browser viewport size. It registers its own data module, updated in response to browser media queries on a standard set of supported breakpoints. This data and the included higher-order components can be used in your own modules and components to implement viewport-dependent behaviors.


Install the module

npm install @wordpress/viewport --save

This package assumes that your code will run in an ES2015+ environment. If you’re using an environment that has limited or no support for such language features and APIs, you should include the polyfill shipped in @wordpress/babel-preset-default in your code.


The standard set of breakpoint thresholds is as follows:

Name Pixel Width
huge 1440
wide 1280
large 960
medium 782
small 600
mobile 480

Data Module

The Viewport module registers itself under the core/viewport data namespace and is exposed from the package as store.

import { select } from '@wordpress/data';
import { store } from '@wordpress/viewport';

const isSmall = select( store ).isViewportMatch( '< medium' );

The isViewportMatch selector accepts a single string argument query. It consists of an optional operator and breakpoint name, separated with a space. The operator can be < or >=, defaulting to >=.

import { select } from '@wordpress/data';
import { store } from '@wordpress/viewport';

const { isViewportMatch } = select( store );
const isSmall = isViewportMatch( '< medium' );
const isWideOrHuge = isViewportMatch( '>= wide' );
// Equivalent:
//  const isWideOrHuge = isViewportMatch( 'wide' );

Higher-Order Components

This package provides a set of HOCs to author components whose behavior should vary depending on the viewport.


Higher-order component creator, creating a new component which renders if the viewport query is satisfied.


  • withViewportMatches


function MyMobileComponent() {
    return <div>I'm only rendered on mobile viewports!</div>;

MyMobileComponent = ifViewportMatches( '< small' )( MyMobileComponent );


  • query string: Viewport query.


  • Function: Higher-order component.


Store definition for the viewport namespace.



  • Object


Higher-order component creator, creating a new component which renders with the given prop names, where the value passed to the underlying component is the result of the query assigned as the object’s value.


  • isViewportMatch


function MyComponent( { isMobile } ) {
    return <div>Currently: { isMobile ? 'Mobile' : 'Not Mobile' }</div>;

MyComponent = withViewportMatch( { isMobile: '< small' } )( MyComponent );


  • queries Object: Object of prop name to viewport query.


  • Function: Higher-order component.
