 Note that Emacs won’t vertically split a window (i.e., into two side-by-side 
windows) that has wide margins. As a result, displaying buffers such as 
`*Help*` buffers, `*Completion*` buffers, etc., won’t split a window 
vertically, even if there appears to be enough space for a vertical split. This 
is not problematic, but it may be undesirable. To remedy this, you can set the 
option `split-window-preferred-function` to 
`visual-fill-column-split-window-sensibly`. This function first unsets  [...]
 
+The width of the margins is adjusted for the text size. However, interactive 
adjustments (e.g., with `text-size-adjust`) cannot be detected by 
`visual-fill-column-mode`, therefore if you adjust the text size while 
`visual-fill-column-mode` is active, the margins won't be adjusted. To remedy 
this, you can force a redisplay, e.g., by switching buffers, splitting and 
unsplitting the window or calling `redraw-display`.

+Alternatively, you can advise the function `text-size-adjust` (or whatever 
function you use to adjust the text size) with the function 
`visual-fill-column-adjust-window`:
