Presenter '13: How to Determine the Optimal Slide Size for Mobile Devices

Article Last Updated

This article applies to:

Optimizing your slide size for mobile devices depends on a number of factors, including:

  • Whether you publish for Articulate Mobile Player (AMP), HTML5, or both
  • The player features you add to your content
  • The aspect ratio of learners' mobile devices

If you plan to include AMP output when you publish, use the AMP sizing guidelines below—even if you also publish for HTML5. On the other hand, if you'll only be distributing HTML5 output, jump to the HTML5 sizing guidelines.

Optimizing Content for the Articulate Mobile Player

The AMP app is locked at a 4:3 aspect ratio on mobile devices. As a result, it won't completely fill a widescreen device. To optimize your content to fill the app, use the following guidelines to calculate the optimal width and height, based on the player features you plan to include in your course, then use those numbers to set your slide size in Articulate Presenter.

 Pixels (px)Inches (in)Centimeters (cm)
No player features968 px wide
668 px high
10 in wide
6.9 in high
25.4 cm wide
17.53 cm high
Sidebar–200 px from width–2.07 in from width–5.25 cm from width
Player tabs–8 px from height–0.08 in from height–0.21 cm from height
Seekbar and/or navigation buttons–48 px from height–0.5 in from height–1.26 cm from height

Tip: Published output is measured in pixels, but PowerPoint uses inches or centimeters, depending on your regional settings in Windows.

Optimizing Content for HTML5

Presenter's HTML5 output is supported on Apple devices running iOS 6 or later. Because Apple devices have changed aspect ratios over the years, it can be difficult to choose the best size for your course. Not to worry. Just use the following interactive calculator to determine the optimal slide size (details below).

  1. First, select an aspect ratio from the drop-down list for the most common mobile device your learners will be using. If you're not sure which devices they're using, we recommend using 4:3. Here are the aspect ratios for supported Apple devices.

    iPhone 6, 6 PlusiPad Mini (all models) 
  2. On the right side of the calculator, choose the player features you plan to include in your course. The slide size will change based on your selections. (Learn how player features affect course dimensions.) If you don't need to add any player features, just skip to the next step.
  3. Since PowerPoint uses different units of measurement, you'll need to convert the calculated dimensions from pixels to inches or centimeters (see the converter below), then use those dimensions to set your slide size in Presenter.

    To use the converter below, select inches or centimeters as your unit of measurement, then enter the pixel dimensions from the size calculator above and click Convert.

Tip: You can use different measurements than those recommended by the size calculator as long as you maintain the same aspect ratio. For example: If the calculator determines your optimal slide size is 1000 pixels x 500 pixels, you can use 2000 x 1000, 1500 x 750, etc.
