Assumed I have this MWE to align the units off right:




Unfortunately the bracket does not fit to the height of the unit.
The units exponent is already positioned above the upper edge of the bracket. :-(

    A = B + C       \tagaddtext{[\si{\square\meter}]}

How can I change this behavior?

Description of the eyesore:

As you can see the corresponding brackets do not automatically adapt to the height of the unit. The exponent is higher than the bracket.

How can I change that behavior, so that the brackets will automatically adjust to the height of the highest/lowest point of the unit?

    You can use \tagaddtext{$\left[\si{\square\meter}\right]$}. But this is usually not recommended. The image you show is the correct behavior AFAIK. – Peter Grill Dec 6 '18 at 19:44
  • @PeterGrill: Thanks a lot! Could I implement the brackets into the \newcommand-configuration already? So that I only have to write \tagaddtext{\si{\square\meter}} into the document text and the brackets will show up automatically? – Dave Dec 6 '18 at 19:47
  • @PeterGrill: Excuse me, one more question: Why is your approach usually not recommended? Is it faulty typography to increase the brackets size matching to the exponents? – Dave Dec 6 '18 at 21:57
  • @PeterGrill: Ah, I understand! Thank you very much for your help! I will stop using \left[ ... \right] now at all. I never tought about those spacing problems... – Dave Dec 7 '18 at 8:27

I propose for what it's worth a work-around with flalign and an \addunit command:




 & & A & = B + C & & \addunit{\square\meter}

  • Thanks a lot! So I should stop using \begin{equation}blabla\end{equation}? Or better use \begin{flalign} inside of \begin{equation}? – Dave Dec 6 '18 at 21:46
  • If you want to use \addunit , yes, use flalign in the place of equationflalign can't be used inside another math environment, and flaligned does not exist. – Bernard Dec 6 '18 at 21:51
