Is there a way to create parentheses in math mode that have an extension between that of the commands \big
(too small) and \Big
(too big)? The amsmath package documentation defines the delimiters in this way:
\renewcommand{\big}{\bBigg@\@ne}
\renewcommand{\Big}{\bBigg@{1.5}}
\renewcommand{\bigg}{\bBigg@\tw@}
\renewcommand{\Bigg}{\bBigg@{2.5}}
but if I try with something like
\makeatletter
\renewcommand{\Pbig}{\bBigg@{1.25}}
\makeatother
in the preamble and then I write $\Pbig($
in the code, it doesn't work; it only produces the same results as \big
or \Big
.

Here I use
scalerel
package to create a delimiter that is1.5pt
larger above and below (3 pt total) than\big
. I call it\pig
. I limit the overall width to5pt
While it will technically "work" with any delimiter, it is really intended for either
(
or\{
. Use with[
produces an undesirable line thickness. EDITED to minimize this issue and provide two alternatives.In this manifestation (the intermediate size is a scaled up
\big
), the bracket line thickness is slightly too thick:In this second manifestation, one
\big
is changed to\Big
in the\pig
definition (so that the intermediate size is a scaled down\Big
), and the maximum width was increased to 5.5pt. Now, the bracket line thickness is just slightly too thin:Perhaps one of the versions is [almost] suitable.
