I have put the tikZ picture between begin{figure} and end{figure}. I need to make it bigger. The thing is that when I scale it, it does not look good at all. This is the code:

begin{figure}[H]

centering

begin{tabular}{rc}

& Movies \

Users &

begin{tabular}{ l | c | r }

    &      A    &   B  \ hline

    1 & $tikzmarknode{a11}{r_{1A}}$~ & ~$tikzmarknode{a12}{r_{1B}}$ \ hline

    2 & $tikzmarknode{a21}{r_{2A}}$~  & ~$tikzmarknode{a22}{r_{BA}}$ \ hline  

end{tabular}  

end{tabular}



begin{tikzpicture}[overlay,remember picture]

 draw[stealth-stealth,blue] (a11.north east) --  (a12.north west)

node[midway,above,scale=0.4,black] (dAB)    {contour{white}{$d_{AB}$}};

draw[-stealth,blue] (a21.south east) -- (a22.south   west);

draw[-stealth,blue] (dAB.south) to[out=0,in=80] (dAB.south|-a22);

draw[stealth-stealth] (a11.east) -- (a21.east)

node[pos=0.5,right,scale=0.4,black] (d12) {contour{white}{$d_{12}$}};

draw[-stealth] (d12.north) to[out=0,in=180] ([yshift=-1ex]a12.west);

end{tikzpicture}

end{figure}

Any help? Thank you!

As Joule V is mentioning, you can play make the table bigger. One way of doing this is to play with arraystretch. The problem is that I may misunderstand what you want.
