is it possible to read out the value of \tx (or \txx ... )  for calculations if bodyfont and fontsize is given? \the\tx doesn't work.

Does \showbodyfontenvironment help?

Thank you, Hraban, I know this table. But I think it's too complicated for me to extract from the source what I want. If you had written, use this or that command, I could have done something with it. Now I try it this way:     \setuplayout[grid=yes]     \setupbodyfont[libertinus,12pt]     \setupinterlinespace[1.25\bodyfontsize]      \starttext     \samplefile{tufte}%\par     \startlinecorrection     \switchtobodyfont[10pt]     \setuplocalinterlinespace[1.25\bodyfontsize]     \placefigure [middle,nonumber]{\midaligned{bla blablabla blabla\\ blubdibla blabla bla}}     {\externalfigure[][height=40mm, width=60mm]}     \stoplinecorrection     \samplefile{tufte}\par     \stoptext Greetings and a nice weekend Thomas

No need to extract the sizes of /tx and /txx at compile time - just use the values that are specified on this page: https://wiki.contextgarden.net/Characters_words_and_fonts/Define_the_set_of_...
