Namespace:  System.Windows.Controls
Assembly:  System.Windows (in System.Windows.dll)
public double LineHeight { get; set; }

Property Value

Type: System.Double
The height of each line in pixels. A value of 0 indicates that the line height is determined automatically from the current font characteristics. The default is 0.
ExceptionCondition
ArgumentException

LineHeight is set to a non-positive value.

Dependency property identifier field: LineHeightProperty

Changing the LineHeight value does not change the height of the associated text. Instead, it changes the height of the line that contains the text. To change the size of the text, use the FontSize property.

The layout of lines in a RichTextBox element is affected by this property and by the LineStackingStrategy property. This property is used to set the height of each line containing text when LineStackingStrategy property is set to BlockLineHeight or BaselineToBaseline. When LineStackingStrategy property is set to MaxHeight, the larger of calculated LineHeight or set value of LineHeight property is set as the LineHeight.

If LineHeight properties of a RichTextBox and its Block element differs, the LineHeight property of the Block will be honored.
