Label.Height Property (Access)
Gets or sets the height of the specified object in twips. Read/write Integer.
For report controls, you can set the Height property when you print or preview a report only by using a macro or an event procedure specified in a section's OnFormat event property setting.
Microsoft Access automatically sets the Height property when you create or size a control or when you size a window in form Design View or report Design view.
The height of controls is measured from the center of their borders so controls with different border widths align correctly.
