Hi GA,
The height of cells is displayed in points and pixels rather than in inches. By using GetRowHeightInPixels method we can get the points (row height) in pixels. Use the following code snippets to get points in pixels.
//Set the row height in points.
sheet.Range["A1"].RowHeight=18;
//Get the row height (points) in pixels.
sheet.GetRowHeightInPixels(1);
Here is the sample for your reference:
