Why is Excel VBA Row Height not equal to Range Height

Question

The following two methods are returning different results and I'm trying to understand what the relationship is.

Method 1: I manually set the row height by right clicking on the row. I sum up the height of a few of these rows to get a total height of a range of rows.

Method 2: I use the Range.Height property in VBA to get the total height of that set of rows.

If I simplify my range to just a single row, this will be different in cases where the manual row height is not a multiple of 3, but the relationship does not appear to be linear.

Code to get range height:

Sub range_height()
    MsgBox Range("A1").Height
End Sub

Set row 1 height = 15 and range_height returns a message box of 15.

Set row 1 height = 20 and range_height returns a message box of 19.5.

My ultimate goal is to be able to add padding to a range so that when I copy into PowerPoint, I have identical dimensions and my slides are pleasant to look at. I can do this via trial and error, but I feel like there must be a better way.

Answer 1

I had faced a similar problem while trying to draw lines in excel using VBA. I was using range.top and range.height for deriving the co-ordinates for my work. However, lines were getting drawn at slightly offset location than expected. Further I found that offset was varying with varying row sizes… Finally I figured out that for row height =15, row height and range height were matching. So, I changed all row height to 15, created my lines using VBA and then changed the row height as per requirement. Lines location was now matching my requirement!
