In recent years there has been a big increase in the number of PM brands and they clearly haven't gone down the road of 'one size fits all'. With the increase in the number of brands available there's been an increase in the capsule sizes available. I don't think this matters very much, if at all. Just decide what amount you're looking to take and go from there. The only caution I would add is that some of the bigger sizes are strong doses if you take the amount they suggest on the bottle, so I wouldn't necessarily jump in the deep end, which what taking some of these products would inevitably entail.
