Scale manager


Scale game window, built-in method of phaser.

  • Author: Richard Davey



Setup scale mode in game configuration.

var config = {
    // ...
    parent: divId,

    // Game size
    width: 1024,
    height: 768,

    scale: {
        // Or set parent divId here
        parent: divId,

        mode: Phaser.Scale.FIT,
        autoCenter: Phaser.Scale.CENTER_BOTH,

        // Or put game size here
        // width: 1024,
        // height: 768,

        // Minimum size
        min: {
            width: 800,
            height: 600
        // Or set minimum size like these
        // minWidth: 800,
        // minHeight: 600,

        // Maximum size
        max: {
            width: 1600,
            height: 1200
        // Or set maximum size like these
        // maxWidth: 1600,
        // maxHeight: 1200,

        zoom: 1,  // Size of game canvas = game size * zoom
    autoRound: false
    // ...
var game = new Phaser.Game(config);
  • scale.mode :
    • Phaser.Scale.NONE : No scaling happens at all.
    • Phaser.Scale.FIT : The width and height are automatically adjusted to fit inside the given target area, while keeping the aspect ratio. Depending on the aspect ratio there may be some space inside the area which is not covered.
    • Phaser.Scale.ENVELOP : The width and height are automatically adjusted to make the size cover the entire target area while keeping the aspect ratio. This may extend further out than the target size.
    • Phaser.Scale.WIDTH_CONTROLS_HEIGHT : The height is automatically adjusted based on the width.
    • Phaser.Scale.HEIGHT_CONTROLS_WIDTH : The width is automatically adjusted based on the height.
    • Phaser.Scale.EXPAND : The Canvas's visible area is resized to fit all available parent space like RESIZE mode, and scale canvas size to fit inside the visible area like FIT mode.
    • Phaser.Scale.RESIZE : The Canvas is resized to fit all available parent space, regardless of aspect ratio.
  • scale.autoCenter :
    • Phaser.Scale.NO_CENTER : The game canvas is not centered within the parent by Phaser.
    • Phaser.Scale.CENTER_BOTH : The game canvas is centered both horizontally and vertically within the parent.
    • Phaser.Scale.CENTER_HORIZONTALLY : The game canvas is centered horizontally within the parent.
    • Phaser.Scale.CENTER_VERTICALLY : The game canvas is centered both vertically within the parent.

Resize canvas element

scene.scale.resize(width, height);

Modify the size of the Phaser canvas element directly. You should only use this if you are using the NO_SCALE scale mode,

Set game size

scene.scale.setGameSize(width, height);

It should only be used if you're looking to change the base size of your game and are using one of the Scale Manager scaling modes, i.e. FIT. If you're using NO_SCALE and wish to change the game and canvas size directly, then please use the resize method instead.

Get view port

var viewport = scene.scale.getViewPort();
// var viewport = scene.scale.getViewPort(camera, out);
  • viewport : The Rectangle of visible area.
  • camera : The camera this viewport is respond upon.
  • out : The Rectangle of visible area.


  • The un-modified game size, as requested in the game config (the raw width / height), as used for world bounds, cameras, etc
    var gameSize = scene.scale.gameSize;
    • gameSize.width, gameSize.height
  • The modified game size, which is the auto-rounded gameSize, used to set the canvas width and height (but not the CSS style)
    var baseSize = scene.scale.baseSize;
    • baseSize.width, baseSize.height
  • The size used for the canvas style, factoring in the scale mode, parent and other values.
    var displaySize = scene.scale.displaySize;
    • displaySize.width, displaySize.height
  • The size of parent dom element
    var parentSize = scene.scale.parentSize;
    • parentSize.width, parentSize.height


scene.scale.on('resize', function(gameSize, baseSize, displaySize, previousWidth, previousHeight) {});
  • gameSize : The un-modified game size, as requested in the game config (the raw width / height)
    • gameSize.width, gameSize.height
  • baseSize : The canvas width and height (actually size of canvas)
    • baseSize.width, baseSize.height
  • displaySize : Size used for the canvas style (display size of canvas)
    • displaySize.width, displaySize.height

Update bounds

This method dose not have to be invoked, unless the canvas position, or visibility is changed via any other method (i.e. via an Angular route).


Full screen

Under 'pointerup' touch event :

  • Start full screen
  • Stop full screen
  • Toggle full screen
  • Is full screen
    var isFullscreen = scene.scale.isFullscreen;

Games within an iframe will also be blocked from fullscreen unless the iframe has the allowfullscreen attribute.

Performing an action that navigates to another page, or opens another tab, will automatically cancel fullscreen mode, as will the user pressing the ESC key.


  • Enter full screen
    scene.scale.on('enterfullscreen', function() {}, scope);
  • Enter full screen failed
    scene.scale.on('fullscreenfailed', function(error) {}, scope);
  • Leave full screen
    scene.scale.on('leavefullscreen', function() {}, scope);
  • Full screen unsupport
    scene.scale.on('fullscreenunsupported', function() {}, scope);
  • Leave full screen
    scene.scale.on('leavefullscreen', function() {}, scope);



  • Is portrait orientation
    var isPortrait = scene.scale.isPortrait;
  • Is landscape orientation
    var isLandscape = scene.scale.isLandscape;

Lock orientation

  • orientation : 'landscape', or 'portrait';


scene.scale.on('orientationchange', function(orientation) {
    if (orientation === Phaser.Scale.PORTRAIT) {

    } else if (orientation === Phaser.Scale.LANDSCAPE) {

}, scope);
