big/small delimiters fontsize

Ok this is old news but i am sick of googling it now.

Delimiters can be sized manually (i.e. not with \left \right) with \big \Big \bigg \Bigg. The sizing of these is adjusted (to the better when loading the amsmath package)

Non delimiters (and this includes Integrals and Sums) can be resized with \tiny
\scriptsize
\footnotesize
\small
\normalsize (default)
\large
\Large
\LARGE
\huge
\Huge
