If we have several lines in align environment, with very different complexity, e.g. some nonsense code below

    a&=\int_{\mathbb{R}} \frac{\|b+\frac{\mathcal{C}}{d}\|_{L_2}}{\|\mathcal{E}\|_{L_\infty}}\left(\int_{\mathbb{R}}R(x,y)\right)^\frac{a+\frac{d}{e}}{f}\\

Vertical space very different

The vertical space taken up by two lines are vastly different. It may be a desired feature of LaTeX, but when I have a large block of equations in my paper, it becomes extremely ugly.



  1. Is there any way that can make vertical space taken by each line in align environment similar?
  2. How to make the big equation block in my paper look better?
  • Welcome to tex.sx. This isn't automatic, but should give the result you're looking for. The tallest element in each line is an integral sign, so inserting a \vphantom{\int} in each shorter line will force the lines apart. Dec 29, 2022 at 14:53

    In that longer equation I would be more concerned about the bad spacing to the right of the \leq.

  • @mickep Could you explain more? I also find the spacing disturbing, but I don't know how to improve. Maybe I should flush \leq to the left?

Welcome to TeX.SE, hoep \jot will help you, and the MWE is:


\setlength{\jot}{16pt}%vary how much you like
    a&=\int_{\mathbb{R}} \frac{\|b+\frac{\mathcal{C}}{d}\|_{L_2}}{\|\mathcal{E}\|_{L_\infty}}\left(\int_{\mathbb{R}}R(x,y)\right)^\frac{a+\frac{d}{e}}{f}\\


enter image description here

Another Method (thanks to dalief)

\begin{spreadlines}{10pt}%%change how much you like

also will works

    mathtools has an env for doing that locally: spreadlines

  • What is going on with the letters in the fraction in the exponent? Looks like they overlap with the bar.

  • @mickep I don't think the image is made from the code posted. I get this Dec 29, 2022 at 22:14
