I wouldn't look for any hard and fast rules, but I would definitely think about sizing and how it impacts villains continuing range.

If you're facing a 6bb donk on AhKs5h board with AKdd.

If you make it 12bb total (min raise) - Villains continuing range is all Ax,Kx, QJ/QT/JT, FD's. Maybe even some 5x and mid pairs like 88/99. Obviously anything better than Ax.
If you make it 18bb - Villains continuing range is likely Ax and FDs, and all hand > one pair. Villain may also fold some bad Ax. It's possible he continues with some gutters + BDFDs.
If you make it 20+bb - Villain's continuing range is likely only good Ax, strong FD's (or combo draws) and likely fold all/most Kx and a lot of Ax.

I think the key is just understanding how different these continuing ranges are, and how that impacts the success/fold equity of any subsequent barrels (Turn/River) you make.
