Slide size specifies the area that is visible when the slide is presented or printed. Objects on that slide can still be placed outside this visible area.
Use SlideSize.Width, SlideSize.Height and SlideSize.Orientation properties to obtain slide size and orientation information.
float width = presentation.SlideSize.Width;
float height = presentation.SlideSize.Height;
SlideOrientation slideOrientation = presentation.SlideSize.Orientation;
Dim width = presentation.SlideSize.Width
Dim height = presentation.SlideSize.Height
Dim slideOrientation = presentation.SlideSize.Orientation

using DevExpress.Docs.Presentation;
Presentation presentation = new Presentation();
presentation.SlideSize = new SlideSize(SlideSizeType.A4Paper);
Imports DevExpress.Docs.Presentation
Dim presentation As Presentation = New Presentation()
presentation.SlideSize = New SlideSize(SlideSizeType.A4Paper)
For predefined slide sizes, you can also pass the orientation parameter in the constructor. Slides can be displayed in Portrait or Landscape orientation:
using DevExpress.Docs.Presentation;
Presentation presentation = new Presentation();
presentation.SlideSize = new SlideSize(SlideSizeType.A4Paper, SlideOrientation.Portrait);
Imports DevExpress.Docs.Presentation
Dim presentation As Presentation = New Presentation()
presentation.SlideSize = New SlideSize(SlideSizeType.A4Paper, SlideOrientation.Portrait)
Use the SlideSize(Single, Single) constructor to set a custom size for slides in Document units:
using DevExpress.Docs.Presentation;
Presentation presentation = new Presentation();
presentation.SlideSize = new SlideSize(1600, 900);
Imports DevExpress.Docs.Presentation
Dim presentation As Presentation = New Presentation()
presentation.SlideSize = New SlideSize(1600, 900)
For presentations with custom sized slides, the SlideSize.Type is set to Custom.
