Hello List. I would like some elegant way to diminished font in math formulas... Is there possibility anything as \setupformulas[before={\switchtobodyfont[small]} ]? I need to align formulas, so are not enough to \mathematics {xxxx} Below is my fallback. You can do something smarter? Thanx Jaroslav Hajtmar \defineformula[small][ align=right, strut=yes, spacebefore=, spaceafter=, % before={\switchtobodyfont[small]} ] % Here is my fallback solution: \def\Startsmallformula{\startsmallformula\switchtobodyfont[small] } \starttext \startformula \lim\limits_{x\rightarrow-2^{\mp}}{\arctan\frac{x}{2+x}}=\pm\frac{\pi}{2} \stopformula \startformula f':\; y' = \frac{\sqrt{3}(1+x^2)}{(1-x^2)^2+3x^2} \stopformula \startformula \lim\limits_{x\rightarrow 1^{\mp}}{\frac{x^2+1}{x-1}}=\mp\infty \stopformula \Startsmallformula \lim\limits_{x\rightarrow-2^{\mp}}{\arctan\frac{x}{2+x}}=\pm\frac{\pi}{2} \stopsmallformula \Startsmallformula f':\; y' = \frac{\sqrt{3}(1+x^2)}{(1-x^2)^2+3x^2} \stopsmallformula \Startsmallformula \lim\limits_{x\rightarrow 1^{\mp}}{\frac{x^2+1}{x-1}}=\mp\infty \stopsmallformula \blank[big] \startsmallformula \startalign \NC f(x)\NC = \ln (x^2+2x+2)\NR \NC f(-x)\NC = \ln ((–x)^2 - 2x + 2)\NR \NC -f(x)\NC = -\ln (x^2+2x+2)\NR \stopalign \stopsmallformula \blank[big] \Startsmallformula \startalign \NC f(x)\NC = \ln (x^2+2x+2)\NR \NC f(-x)\NC = \ln ((–x)^2 - 2x + 2)\NR \NC -f(x)\NC = -\ln (x^2+2x+2)\NR \stopalign \stopsmallformula \stoptext
