Hi,

please look at the attachment. I want different interline spacing for  
big, normal and small font sizes. What is the best approach?

I tried \setupinterlinespace[big] (works only after \starttext!) or  
\setupinterlinespace[line=3.5ex] (works also before \starttext) but  
this changes, as intended, interline spacing as a whole.

There is also \setupbodyfontenvironment (Problem with \chapter{…} or  
did I something wrong?). Now I've to use \switchtobodyfont[…] instead  
of \tfa and so on. Is there a trick?
