Maybe it fails but can you give an example?
The question, as far as I understand it, is about the plots' relative
heights, not about horizontal alignment. And (all) others have asked you
to give a reproducible example, please don't ask us to guess a use case
axis labels lengths (!), which is impossible to do.
Anyway, the function cowplot::plot_grid has an argument `align`. One of
the possible values is "hv" for both horizontal and vertical alignment.
Hope this helps,
