How to determine the height of an optiongroup?

[FancyPrairie]

I have an option group whose height is .884 inches. I have routine that converts this option group to a fldlst (web form). Now, if I convert .884 inches to pixels (at 96 dpi) I get 85 (I have code that does the conersion and have used calculators via web sites. So I know this calculation is correct.). When I do a print screen of both the web form and the access form and paste them into Photoshop, the access version of the option group is 10 pixels higher then the web form version. That is, I have to set the height of the web for fldlst to 95 pixels to make them match. Is there something I'm missing in determining the proper height?

Nevermind, figured out the problem. The height (.884) is actually the height + the height of the legend (label). Which explains the difference.
