Thanks Hans. I see my error now. I was using a typescript name where a fontsynonym name was needed. I still have a question about \small and \big. i tried the \showbodyfontenvironment to see the sizes then tried this: {\big Hello world}Hello world{\small Hello world} I get the first and the second Hello world at the same size, where the fonts table shows that i should have \big at 14.3pt when my current size is at 12. Is there any interest to define a new font environment in this case ? This my example: \usetypescriptfile[Karat.tex] \usetypescript[karat] \setupbodyfont[karat,ss,12pt] \starttext \showbodyfontenvironment {\big Hello world}Hello world{\small Hello world} \stoptext Many thanks.
