Storyline 360: Setting Your Slide Size

When you create a new Storyline 360 project, the slide size defaults to 720 pixels wide by 540 pixels high, but you can change it to any size you'd like.

Want to set a new default slide size? As of September 2021, you can define the default slide dimensions for new projects. Learn more.

How to Change Your Slide Size

You can change the slide size, and now's the best time to do so—before you add any content.

Go to the Design tab on the ribbon and click Slide Size. Or, click the slide size dimensions link in the lower-left corner.
When the Slide Size window appears, choose an option from the Preset selector.
- Choose 4:3 (720x540) for a fullscreen slide size.
- Choose 16:9 (960x540) for a widescreen slide size.
- Choose Custom to enter the width and height in pixels up to a maximum of 2,047 x 2,047.
- Mark the Lock aspect ratio box to maintain the current proportions for objects that have locked aspect ratios.
- Mark the box to Scale existing content to fit so that existing slide content fits proportionately within the new size. Objects that have locked aspect ratios will maintain their ratios. Objects that don't have locked aspect ratios may change shape, depending on the slide size you choose.
- As of June 2021, the preset widescreen (16:9) slide size increased from 720x405 to 960x540. If you’re using text autofit improvements, we recommend using the 960 pixels by 540 pixels slide size preset or larger to help avoid scroll bars.
To save the selected dimensions as the default slide size for new projects, click Set As Default Size. (The button is grayed-out for the current default slide dimensions.)
Click OK to accept the new slide size.

Keep in mind:

Your new default slide size takes effect when you close Storyline 360.
As of January 2024, when you change your slide dimensions, Storyline 360 automatically scales font sizes throughout your project to preserve the slide designs and prevent scrollbars from appearing in text boxes.

How Player Features Affect Published Size

The overall size of your published course will be slightly larger than your slide dimensions. That's because the player (the frame around your slides) adds some width and height to the course.

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 select. See the following table for details. (For the modern player style, features have the pixel sizes below when the browser is set to optimal size. These dimensions can change as the modern player responds to different browser sizes.)

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	Width	Height
Player frame*	+20 pixels	+20 pixels
Title		+23 pixels
One or more topbar tabs		+24 pixels
Volume controller, closed captioning button, play/pause button, seekbar, or navigation buttons		+51 pixels
Sidebar	+240 pixels

*The modern player style with menus and controls turned off doesn't add any width or height to your course.

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. Here’s the breakdown:

	Width	Height
Slide size	720 pixels	405 pixels
Player frame	+20 pixels	+20 pixels
Navigation buttons		+51 pixels
Sidebar	+240 pixels
Published Course Dimensions	980 pixels	476 pixels
