Message font size too small

[nvx2004]

I am not sure if this is by design but if I open a longer message (more or less any message that contains at least one or two cited original messages) then the app renders it in a totally illegible (i.e., too small) font size just so that the entire message fits to the available screen space. Please bear in mind that this happens even with "Auto-fit messages" being disabled (Settings > Global Settings > Display > Auto-fit messages). It doesn't even matter if in Settings I choose message body font size to be "200 %" because the app will still use that incredibly tiny font size for longer messages.

Strangely enough, if I rotate the phone and it switches to the landscape mode then the message font size immediately increases (though it will revert to the tiny one if I rotate the phone back). I can only guess that the algorithm estimating the "proper" font size depends significantly on available viewport width.

Shorter messages are displayed normally, i.e., any decrease in font size is not that pronounced and thus the text remains legible.

Would it therefore please be possible to set K-9 to respect some reasonable minimum allowed font size (or perhaps the respective scaling factor)? This could be definable similarly to the current options regarding font sizes of various parts of the UI -- e.g. "Minimum allowed message font size: small". In other words, the font size could decrease for longer messages but only up to a point beyond which the font size would not decrease any further.

Alternatively, the message font size (or, again, the respective scaling factor) could be fixed no matter the actual message length.

Either of these two solutions would be acceptable because it would mean that I would not have to (a) manually zoom in after opening virtually every email I get or (b) look for a magnifying glass in my drawer. ;-)

Thank you.

I am also having this issue, and I second everything said above.

Between this and Outlook bulleted lists not displaying when quoted, I am quite frustrated. I hope these issues get fixed soon.

I had this problem because I set it to use a fixed-width font. Apparently the font size preference isn't respected for fixed-width font: I slid the font size slider up to 250% (the largest available) and it made no difference whatever. But when I finally thought to un-check fixed width, then the font size slider was respected and I could read messages just fine, even at 100% size. (I also un-checked the box about fitting messages to the window, otherwise anything with a long URL shrank the whole message to be tiny.)

Enabling fixed-width font shouldn't affect the text size (and doesn't for me).

I believe the problem has to do with the "Auto-fit messages" setting from the Messages section of the Global Settings->Display menu. What having this on (the default, I think) did was to attempt to format messages in narrow columns, shrinking the font at the same time. Turning it off corrected the problem.
