As you go from \displaystyle
to \scriptstyle
to \scriptscriptstyle
, letters and numbers, for instance, shrink. Weirdly, to my mind, the prime symbol (') shrinks from \displaystyle
to \scriptstyle
, but then is again the same size in \scripstscriptstyle
. For example:
\[
a {\scriptstyle a} {\scriptscriptstyle a} \quad
' {\scriptstyle '} {\scriptscriptstyle '} \quad
a' {\scriptstyle a'} {\scriptscriptstyle a'}
\]
The effect of this is that sometimes (eg in certain sub or superscripts or labels), primes look much too large relative to the surrounding symbols.
How should one produce a properly scriptscriptstyle-sized prime symbol?

The
scalerel
package can do this. I made the scriptscript prime equal to .6 the size of the script prime. One invokes it as\ssp{
base}
to get base'
