Best slide size for responsive course using Storyline 360
I want to generate HTML5 output for use on desktop, iOS, Android tablets and mobile in Storyline 360. What is the optimal slide size I should use?
Hi Karen,
It looks to me like the course used in this example is set up in a 4:3 aspect ratio, which looks fantastic on an iPad. It's hard to see in the screenshot you included, but there is letterboxing on the phone, which has a 16:9 aspect ratio. The screen background, and the letterbox are close in color so it isn't as obvious.
Later on in the video, it shows up more clearly on the phone, so you can see what that kind of horizontal letterboxing looks like.
If the majority of your learners will be viewing your course on a tablet, then 4:3 is probably a great choice for you. If you think that more people will be viewing your course on a phone, you might want to consider 16:9.
