Often I find the delimiters that for example \left( and \right) produce too large.

I know about \big, \Big, \bigg, \Bigg to choose among the sizes

delimiters

but these are sometimes too small. \left( produces one like this:

How can I produce a shorter version of this extended delimiter (which is bigger than \Bigg)?

    Have a look in the amsmath.sty source to see how they are defined. But it might also be an idea to rephrase if you feel you need manual delimiters larger than Bigg – daleif Jun 19 '16 at 20:35
  • @daleif What do you mean by "rephrase"? (Unfortunately I'm not able to make sense of the source code, which can be found here, but there is no \def\left in there.) – Earthliŋ Jun 19 '16 at 20:53
  • That is not how big, Big, etc are defined, look them up instead. Rephrase, rewrite the math (assuming it is a math construction that needs this). Often it is more convenient to write: in order to simplify we define...., then...... For instance huge matrices, which can often be defined by smaller matrices making the huge matrix into say a 2x2 (where each entry might be a 6x6 matrix). – daleif Jun 19 '16 at 20:58
  • \def\big{\bBigg@\@ne} \def\Big{\bBigg@{1.5}} \def\bigg{\bBigg@\tw@} \def\Bigg{\bBigg@{2.5}} \def\bBigg@#1#2{% {\@mathmeasure\z@{\nulldelimiterspace\z@}% {\left#2\vcenter to#1\big@size{}\right.}% \box\z@}}

    Copy/pasting the definition for bBigg doesn't work for me (I also did the \makeat[letter/other])...

    Possible duplicate of About big parentheses larger than Bigg. Edit: Also see mathtools brackets larger than \Bigg. – GuM Jun 19 '16 at 22:02
  • @GustavoMezzetti The possible duplicate answers my question. – Earthliŋ Jun 20 '16 at 05:02
