# Subscript with fraction, large vertical spacing

In a paragraph, the expression $A_{b/c}^{dd}$ causes an undesired larger vertical spacing of the sentence where it appears (compared to the rest of the paragraph). I have tested some solutions (eg. /*tensor, /subdepth packages) from similar problems to no avail. Is there a way to handle this properly?

• It is being handled correctly! :) You can always \smash{..} it, but then you may have descenders/ascenders sticking into it. – Werner Apr 12 '14 at 17:10
• Welcome to TeX.SX! It doesn't happen with the Computer Modern fonts, but I can see it with mathptmx. Can you please give a minimal working example (MWE)? The problem with mathptmx seems to be in a too big slash. – egreg Apr 12 '14 at 17:21
• You may need smash even more in case you have: ... some text $\smash{A_{\frac{b}{c}}^{dd}}$ more text ... check this out... – MattAllegro Apr 12 '14 at 19:14

You can make TeX ignore the height of a formula with the \smash command. Try
... some text $\smash{A_{b/c}^{dd}}$ more text ...

The \smash macro is provided by plain TeX and it sets the height and depth of a maths subformula to zero. Beware that this might make your subscripts and superscripts overprint the lines above or below.
