This value contains the height of this PDF text object in PDF units (1/72 of an inch and bottom left). You can use the PDFDocumentPage.ConvertPoint method to convert the value to a pixels or inches and then to points if required. Here is an example:
// Get the font height in PDF units, which 1/72 of an inch, i.e. in points
double fontHeightPoints = pdfObject.TextProperties.FontHeight;
// Convert to inches:
double fontHeightInches1 = fontHeightPoints / 72.0;
// Or use PDFDocumentPage.ConvertPoint to convert to inches:
PDFPoint pt = new PDFPoint(0, fontHeightPoints);
double fontHeightInches2 = pdfDocumentPage.ConvertPoint(PDFCoordinateType.Pdf, PDFCoordinateType.Inch, pt).Y;
// And pixels:
double fontHeightPixels = pdfDocumentPage.ConvertPoint(PDFCoordinateType.Pdf, PDFCoordinateType.Pixel, pt).Y;
This value contains the external and internal leading of the text item, to get the bounds of the box that exactly surrounds the text object, use PDFObject.Bounds.
