Presenter 360 lets you control several attributes of the browser and player for your published course.

First, go to the Articulate tab on the PowerPoint ribbon and click Player. When the player properties appear, click Other on the ribbon. Then, follow the steps below to change the browser and player settings.

Choosing the Browser Size

You can define how learners’ browsers behave when they launch your course in a new window on desktop computers. (On mobile devices, the browser always fills the screen.) Use the Browser size drop-down to choose one of these options:

Display at user’s current browser size

This displays the course using the learner's current browser size.

Resize browser to optimal size

This automatically resizes the learner's browser to match the course's optimal size.

The optimal size is whatever you chose as your slide size plus additional width and height to accommodate the player frame.

Depending on the features you include in your player, it adds between 20 and 260 pixels to the width of your course and between 20 and 118 pixels to the height. See below for details.

Resize browser to fill screen

This automatically resizes the learner's browser to fill the whole screen.


Choosing the Player Size and Output Slide Size

You can control the size of your course on desktop computers. (On mobile devices, your course fills the screen and the player appears as a bar along the side or bottom of the screen.) Select one of these options from the Player size drop-down list.

Scale player to fill browser window

This scales your published course to fill the learner's browser window.

Lock player at optimal size

This locks the published course at its optimal size. Even if learners resize their browser windows, the course itself will stay at its optimal size.

By default, the optimal size is 720 pixels wide plus an additional 20 to 260 pixels for the player frame, depending on the features you included. The height will adjust to maintain the aspect ratio of your content plus an additional 20 to 118 pixels for the player frame. See below for details.


If you lock the player at optimal size, you can also adjust the fixed dimensions of your published output. Choose one of the following Output Slide Size options. (These options will be grayed-out if you scale your player to fill the browser.)

Use a fixed width of 720 pixels

This is the default setting. It locks your published slides at a width of 720 pixels and adjusts the height to maintain the proper aspect ratio.

Percentage of PowerPoint slide size

This scales the published output to a percentage of the PowerPoint slide dimensions.

For example, if you choose 100%, your published output will be locked at the same size as your PowerPoint slides.

Tip: The numbers in parentheses are the actual dimensions Presenter will use for your published slides. These dimensions automatically adjust as you change the percentage.


Calculating the Dimensions of Your Published Course

The overall size of your published output will be slightly larger than your slide dimensions. That's because the player adds some width and height when your course is viewed on desktop computers.

The player adds up to 260 pixels to the width and up to 118 pixels to the height, depending on the player features you choose. See the following table for details.

You can also enable and disable player features on a slide by slide basis, but the course size will remain the same for all slides—i.e., each player feature adds some width or height to your published course, even if it’s only used on a single slide.

Player Feature



Player frame (with or without player features)

+20 pixels

+20 pixels

Title or duration


+23 pixels

One or more topbar tabs


+24 pixels

Volume controller, seekbar, or navigation buttons


+51 pixels


+240 pixels



Here’s an example: Let's say your slide size is 720 x 405 and you enable the navigation buttons and sidebar. The overall dimensions of your published course are 980 x 476. (This is also known as the optimal size of your course.) Here’s the breakdown:




Slide size

720 pixels

405 pixels

Player frame

+20 pixels

+20 pixels

Navigation buttons


+51 pixels


+240 pixels


Published Course Dimensions

980 pixels

476 pixels

Launching the Course in a New Window

You can launch your course in a new browser window (or a new browser tab on mobile devices). Just mark the box to Launch player in new window. This adds a launcher.html file to your published output. Give learners a link to the launcher.html file rather than the default presentation.html file.

When you launch a course in a new browser window, you also get to decide how the new window behaves on desktop computers. Choose from the following options. (These options don’t apply to tablets and smartphones.)

Display window with no browser controls

If you mark this box, the new window will have no browser controls. It'll only display the address bar, which won’t be editable.

If you don’t mark this box, the new browser window will have the same controls as the parent window.

Allow user to resize browser

Mark this option to let learners resize the browser window.

Saving Player Changes

When you click OK to close the Player Properties window, Presenter saves your changes in the current project file.

If you'd like to use the same customizations in other projects, click Current Player on the ribbon and choose Save. Enter a name for your custom player if you're prompted and click OK.

To learn more about the Current Player options, see this user guide.
