This is with the default settings (as far as I know, haven’t used this program before), with the default font size, and zoom level (if you can see in the bottom right corner) set to 100%.
This is clearly too tiny. It would maybe be understandable on some crazy high DPI screen, but this is 1440p. So something is not right.
So what my friend wants to know: how do I make it look bigger?
And by this, my friend doesn’t mean “how do I zoom in?” or “how do I choose a bigger font?” or “how do I modify the document to make it bigger?”, but how to make it display properly, without modifying the document.
Looking it up online, I see something about adjusting some scaling factor (setting “Scaling” in Tools > Options > LibreOffice > View), but I can’t find an option like that anywhere.
My friend says thanks!
EDIT: here is a better explanation of the problem:
I’m sorry, I seem to be getting misunderstood by many people, so obviously, I didn’t explain it well enough.
On my 1440p monitor, there are 70 rows and 29 columns of spreadsheet visible, at zoom level 100% and with the font size 10pt.
This is too tiny. It looks as if the zoom level is set to 20% or something small like that. But this is at 100%. So in order to see anything, I need to zoom in, to something absurd like 300% (400% is the limit!). And then, when I save the document, it remembers this zoom level. So when I send it to my friend, who uses a laptop with a smaller screen, he is going to see only the A1 cell and nothing else, because it’s going to be zoomed in so much…
So zoom doesn’t seem to be an issue here, this is some high DPI problem.
So your goal is to have the font in the spreadsheet significantly larger than the menu font and other ui elements? Since it looks like in your screenshot they are currently at similar scales. Is the font in Kate also 10pt?
If you’re not attached to spreadsheet operations, you could increase the font size and save in a format like csv that doesn’t store font size.
Alternatively, if they’re using libreoffice too, you can both turn off Options → Load/Save → General → Load user-specific settings with the Document so you don’t load each other’s zoom settings. I think some other file formats also don’t save zoom settings (certainly something like csv, maybe others like xlsx or dif).
env SAL_USE_VCLPLUGIN=gtk3 GDK_SCALE=1 SAL_FORCEDPI=300 libreoffice looks like it scales the font but not the ui. GDK_SCALE controls the ui scale here, while SAL_FORCEDPI scales the content. You get a similar effect with slightly different things scaled using env SAL_USE_VCLPLUGIN=qt5 QT_SCALE_FACTOR=1 SAL_FORCEDPI=300 libreoffice.
