We may notice that the numerator and denominator in the following fraction are not aligned. And, to me it does not look good.

How to align the numerator and denominator?



\let\xoverline\overline % supply your definition



The above yields:

    Not a real improvement, but here it is: \frac{1-k^{m+n+d}}{1-k^{\hphantom{m+n+d}}}

  • @student What is the easiest way to do that?

  • In my opinion, aligning them is not a good idea, since the terms are importantly different. As well, as @egreg points out, the "aligned" result is not much good nicer. You can maybe shift the denominator just slightly: \dfrac{1-k^{m+n+d}}{1-k\quad} But I'm not sure it looks nicer than the default one.

    @tohecz I'd definitely use the default centering.

Here's a comparison of the proposed solutions; the name next to the fraction doesn't necessarily denote the suggestion author's preference.

\makebox[2in][l]{1. Original}$\dfrac{1-k^{m+n+d}}{1-k}$


\makebox[2in][l]{2. egreg}$\dfrac{1-k^{m+n+d}}{1-k^{\hphantom{m+n+d}}}$


\makebox[2in][l]{3. projetmbc}$\dfrac{1-k^S}{1-k}, \text{ with $S=m+n+d$}$


\makebox[2in][l]{4. Peter Grill}$\dfrac{1-k^{\mathrlap{m+n+d}}}{1-k}$


Take your pick.

Everybody can add here their personal preference.
