The margin sizes provided by the achemso template are larger than what I need. I'd like to have leeway to change the margins as I desire, but using the geometry package leads to a clash for the geometry of the paper, indicating to me that achemso has immutable default margin sizes. I'm taking issue with the "immutable" part: I like achemso, it's served me well so far, but I'd be so happy if I were able to tamper a bit with the margins for compactness.

As a bonus, I'd highly appreciate a MWE demonstrating not only how to change the margins, but also how to customize them based on whether a page is odd or even (larger right margin for the even page, larger left margin for the odd page).

    The class is purely for manuscript submissions to the ACS: what's the target for your document?

  • Definitely not the ACS. Target: my nitpicky TAs. Commented Feb 2, 2023 at 20:49

Things should mainly 'just work', though you may need to adjust the lengths used by \maketitle, e.g.

\geometry{margin = 2in,a5paper}
\title{Some things I did}
\email{[email protected]}
\affiliation{Some Edu}

    Note that the class is purely for submission to the ACS: I would strongly urge simply using article and adjusting as needed.

  • Thank you, but I don't really see how this helps with customizing margin sizes. I could only get rid of the spaces near the title/author/email etc. Commented Feb 3, 2023 at 14:22

    @TheRelentlessNucleophile I've added a margin change: my point was that you can set whatever you like using geometry after it's been loaded provided you do it using \geometry rather than as package options

  • I don't know how to thank you enough. This is exactly what I've been looking for. Please, accept my gratitude. Commented Feb 3, 2023 at 14:55
