$\sum\limits_{\substack{locations \\ L_j}}$
The word locations is quite long - longer than the summation symbol Sigma.
I would like to control the size of only the word locations, but I am having trouble
$\sum\limits_{\substack{ locations \\ L_j}}$
has no effect on the size of locations.\fontsize{0.5cm}{1pt}\selectfont $\sum\limits_{\substack{locations \\ L_j}}$
makes the summation symbol sigma smaller but not *locationsinserting
\tiny
,\scriptsize
etc has no discernable affect. Nor does\text{\tiny locations}
, etc.
