fancyhdrheader-footerhorizontal alignment
I have the following code for my footer:
\usepackage{fancyhdr}
\lhead{}
\rhead{}
\chead{My very important and long title that is not being centered as I would like to \newline Very Myself}
\cfoot{\thepage}
\setlength{\headheight}{14pt}
but it is not centered:
How can I center it? I am using \documentclass[11pt,a4paper]{article}
If you don't set a proper head height, fancyhdr reports the following:
Package Fancyhdr Warning: \headheight is too small (XX.Xpt):
Make it at least YY.YYYYpt.
We now make it that large for the rest of the document.
This may cause the page layout to be inconsistent, however.
As such, the newly-set \headheight will be the same throughout the document. To avoid this, I've created the following minimal document that sets a consistent head height, adding a vertical space (gap) on the first page to simulate a larger header:
\documentclass{article}
\usepackage{fancyhdr,datetime,geometry,lipsum,graphicx}

I've used geometry to adjust the page layout - it's just easier/more convenient.
There are not random results but inconsistent settings. Please use the option showframe in the package geometry and see the log file to understand what happen with your settings.
Take into account that top margin in Lyx should be 15 mm plus headheight plus headsep and that header text should be enough small to fit in the headheight, otherwise LaTeX will change his setting trying to do the best.
In the same way, bottom margin should be 15 mm plus the footskip, but the footer text must fit within the foot skip.
Taking this into account, you can already fix without problems the margins using the normal menu of LyX (Documents>Settings...>Page Margins), but there are nothing wrong checking "Defaults Margins" box and using the package geometry directly in Documents>Settings...>LaTeX preamble. This allow you to use options of geometry that LyX cannot manage, or use dynamic dimensions, so the margins are calculated correctly independently of the default font size:
\documentclass{article}
\usepackage[paperheight=16cm,paperwidth=14cm,showframe]{geometry}
\geometry{
lmargin=15mm,
rmargin=15mm,
tmargin=\dimexpr15mm+1.5\baselineskip,
bmargin=\dimexpr15mm+1.5\baselineskip,,
headheight=\baselineskip,
headsep=.5\baselineskip,
footskip=1.5\baselineskip}
\usepackage{lipsum}
\usepackage{fancyhdr}
\pagestyle{fancy}
\begin{document}
\section{Testing margins}
\lipsum*[1]\footnote{A foonote}
\lipsum*[2]\footnote{A foonote}
\lipsum*[3-5]
\end{document}
Some like \chead{\Huge A} just at the end of the preamble will ruin this layout, but LaTeX warn you in the .log file:
Package Fancyhdr Warning: \headheight is too small (12.0pt):
Make it at least 30.0pt.
We now make it that large for the rest of the document.
This may cause the page layout to be inconsistent, however.
Also, as you can see in this MWE, the footnotes are not a problem at all, since they are included in the text area, not in the margins.
On the other hand, for a 12pt article the default font size in footnotes (\footnotesize) is 10pt, so you must use a \scriptsize. See What point (pt) font size are \Large etc.? and Set font size for footnotes.

Use
\\and not\newline. The behavior is easily reproducible:gives
Here's the code for you
The command
\\changes its meaning when in a\centeringcontext, which is in force in\chead, whilst\newlinedoesn't.
