I use Adobe Garamond Pro in combination with Termes Math for math (the latter for missing glyphs, Garamond is not very complete). How can I scale size of Termes Math without decreasing the size of the Garamond glyphs in math mode? /MJO % define the characters to use for Garamond in math mode \definefontfamilypreset [math:somesymbols] [range={0x0002A-0x0002E,0x000A7,0x000B6,0x000D7,0x000F7,0x02020-0x02021,0x02212,0x02219-0x02226,0x02228-0x02265,0x02012,0x0003C-0x0003E,0x0007C}, tf=style:regular, offset=lowercasenormal, ] \definefallbackfamily[mainface][mm][Adobe Garamond Pro][math:digitsnormal] \definefallbackfamily[mainface][mm][Adobe Garamond Pro][math:lowercasenormal] \definefallbackfamily[mainface][mm][Adobe Garamond Pro][math:lowercaseitalic] \definefallbackfamily[mainface][mm][Adobe Garamond Pro][math:uppercasenormal] \definefallbackfamily[mainface][mm][Adobe Garamond Pro][math:uppercaseitalic] \definefallbackfamily[mainface][mm][Adobe Garamond Pro][math:somesymbols] \definefontfamily[mainface][rm][Adobe Garamond Pro] \definefontfamily[mainface][mm][TeX Gyre Termes Math][scale=0.9] % <-- scaling here... \setupbodyfont[mainface,11pt] \starttext 100 $100$ % <-- leads to math mode that is smaller than text, even for Garamond glyphs \stoptext
