Property Value

A SizeF containing the dots per inch (DPI) or Font size that the control was designed to.

Exception typeCondition


The width or height of the SizeF value is less than 0 when setting this value.

The AutoScaleDimensions property represents the DPI or font setting of the screen that the control was scaled to or designed for. Specifically, at design time this property will be set by the Windows Forms designer to the value your monitor is currently using. Then, when the form loads at run time, if the CurrentAutoScaleDimensions property is different from the AutoScaleDimensions, the PerformAutoScale method will be called to perform scaling of the control and all of its children. Afterwards, AutoScaleDimensions will be updated to reflect the new scaling size.

For more information about automatic scaling, see Automatic Scaling in Windows Forms.
