Remarks

The range of asset scale values that can be provided to MakeAppX for a UWP app is limited to 100, 125, 150, 200, 250, 300, 400 and 500.

For more info on scaling to pixel density, see UX guidelines for layout and scaling.

The Scaling according to DPI sample shows how to use the ResolutionScale enumeration.

For UWP apps and Windows Phone apps, we recommend these scale factors:

• UWP app (100/140/180)
• Windows Phone apps for Windows Phone 8.1 and later (100/140/240)
• Windows Phone apps for Windows Phone 8 (100/150/160)
