# different spacing aroung equal sign for display/text mode [duplicate]

as I wanted to increase the space surrounding the = sign in my equations, I changed the thickmuskip length in the preamble

\setlength{\thickmuskip}{14mu}


It works fine, and I like the result in display-style equations. The problem is that it also affects equations written in text-style (ie those with ) and there it does not look good. How can I get a different spacing around = in display and text mode?

Thanks

• However adding \everydisplay{\medmuskip=10mu\relax} as suggested in the answer causes an error for me, in the amsmath package: \begin{split} won't work here. The document builds perfectly without the \everydisplay – Bruce Jun 27 '14 at 13:00
• Solved with \everydisplay=\expandafter{\the\everydisplay\thickmuskip=14mu\relax}. See answer by Matthew Leingang – Bruce Jun 27 '14 at 13:11
