I've had a lot of instances where I tried to skip discussing on this topic of marriageable age because I think no matter what my opinion is, it is soemthing that every individual have their right to decide. Nobody will assist you in your marriage, you make your decision to marry so you get to bear with whatever comes out of that decision.
Marriage is a very important stage of life that isn't for children as in the old days where teen girls are married to older guys without much prior guides on how they should live in a marriage home. While that ended well for many, it also didn't go well for many. Immature people marriage is not advisable and it rarely ends well.
Coming from that perspective, that marriage are only for matured minds, I think I can say without worries of going against another's thought that, the age doesn't matter when love that is leading to marriage happens. What should matter more is, if the parties involved are matured and are well aware of what they are getting themselves into.

When marriages go wrong, so many things are affected especially the children brought into that marriage. It is why it's important to consider very well who one is tying the knot with to father or mother their children. Small minds or immature minds won't think of all these but focus more on their wedding ceremony would turning out great.
The word "limit" in marriage should be to keep children away from getting married. And by children, I mean those who know little to nothing about what marriage entails. Instead, they should be made to learn and understand the dynamics of marriage so they could be more prepared for when love hits and they want to push further.
Understanding that there are lusts, infatuations and then there is love is also an important factor to consider before agreeing that one is ready to go the marriage road. The age could not be reasonable to many around but if there is a good understanding of their feelings for each other, it wouldn't matter what others may think anymore.

I've had conversations with a guy who says he's not attracted to girls his age or younger, he loves to be with women older than him. While I didn't try to picture him in black, I figured he haven't considered getting married to any of them because he said something about his parents not liking how he hooks up with only older women.
We also hear of ladies who hook up with older men but mainly to make money out of them, only few actually got married to them. Somehow, the society knows when they are in love or just being after something they want to gain regardless of the age differences. But when it's about real love, the understanding of marriage should matter.
I believe any age differences can marry so long both are of marriageable age or matured to make their own decisions. I'm not sure how it would actually be like when a guy marries an older woman or a girl marry an older man but I believe there will always be some perks to such marriage so the decision should be on the parties involved.
