AccessText.LineHeight Property


The .NET API Reference documentation has a new home. Visit the .NET API Browser on to see the new experience.

Gets or sets the height of each line box.

Namespace:   System.Windows.Controls
Assembly:  PresentationFramework (in PresentationFramework.dll)

public double LineHeight { get; set; }

Property Value

Type: System.Double

A double that specifies the height of each line box. This value must be equal to or greater than 0.0034 and equal to or less then 160000. A value of Double.NaN (equivalent to an attribute value of Auto) causes the line height to be determined automatically from the current font characteristics. The default is Double.NaN.

Changing this value does not change the height of the associated text; instead, it changes the box that contains it. To change the size of the text, use the FontSize property.

A string representation of a Double value. This value is interpreted as a device-independent unit (1/96th inch) measurement. Strings need not explicitly include decimal points. For example, you can specify a value of 1.

The same Double range restrictions as mentioned in the Property Value section apply here.


A double value that is followed by one of these unit declaration strings: px, in, cm, pt.

px (default) is device-independent units (1/96th inch per unit)

in is inches; 1in==96px

cm is centimeters; 1cm==(96/2.54) px

pt is points; 1pt==(96/72) px


An automatic line height determination. If you programmatically set the Auto value, its value corresponds to Double.NaN.
