(My rating system for ships might be a little bit unusual. Anything six and above I ship, anything below six I don't really like. There is also literally only one ship in the entire book series that I would rate 10/10, so keep that in mind.)
(Also, please remember that these are my OPINIONS. You are welcome to ship and not ship whatever you want, regardless of my or anyone else's personal opinions. Literally whatever. I don't care if you ship Mcgonagall and the Giant Squid. These are fictional characters.)
- Harry/Ginny: We're starting here with the main character and his canon love interest. A pretty popular ship in the fandom, but not one that I personally consider an OTP. It's good in principle, and, to be honest, if it weren't canon, I'd probably ship it a lot more. As it is, the actual romance in the book was quite underdeveloped. I do not, by any means, dislike this ship. I just think it wasn't written particularly well. 6/10
- Ron/Hermione: The biggest and most developed canon relationship in the books is clearly going to be a favourite for a lot of people. I definitely ship it more than Hinny, but again, I can't say that I love it. I've got to be honest here. Ron and Hermione argue a little too much for me to be convinced they're going to have a healthy relationship. Their dynamic is interesting, but not necessarily my favourite thing. 7/10
- Neville/Luna: I actually used to ship Neville and Luna a lot. And then I kind of became annoyed at myself for completing the circle and pairing the only two main male and female characters who didn't have romantic interests together. And, no, Hannah Abbot and fucking Rolf Scamander do not count as canon love interests. I mean, the ship is fine on principle and kind of cute, but I just can't. The series is already too straight. 5/10
- Draco/Harry: This is possibly the most popular ship in the fandom and... I totally get why. There is an incredible amount of subtext for it in the books. I personally love this ship as an unrequited crush on Draco's part. I can't see a relationship between these two characters actually working out, but really who gives a fuck about that. It's a really interesting dynamic. 9/10
- Harry/Luna: The friendship between Harry and Luna is one of my favourite relationships within the canon of the series, and I'm not necessarily opposed to shipping them romantically. I really like their dynamic. 7/10
- Harry/Ron: I like the canon friendship between Harry and Ron, but I have to say that it's not even close to being one of my favourite relationships in the series. A romantic relationship between the two of them is even less interesting to me. 4/10
- Harry/Hermione: I like their friendship, but I just don't ship them romantically. I'm sorry, their canon interactions just make it impossible for me to think of them as having anything other than a platonic relationship. 3/10
- Hermione/Ginny: Yay! Femslash! There are too few femslash ships in the fandom, and this is one of my favourites. I think the two would mix really well together, even though I generally headcanon Hermione as straight. Overall, a pretty cool ship. 7/10
- Hermione Draco: This ship is possibly the most popular non-canon f/m pairing and I have to be completely honest. I don't get why. Not only do I not see a relationship between these two working, I just honestly don't find their potential dynamic very interesting. At all. And I have a hard time shipping Draco or any other prejudiced Slytherin with a muggleborn like Hermione. 1/10
- Hermione/Luna: I feel bad about not being able to ship this, but I just can't. I am in favour of all femslash, but I just can't personally make myself to like even a friendship between these two. They're just too different and their personalities do not mesh well. 5/10
- Ron/Draco: This is one of those ships that I don't really have an opinion on. I don't particularly find it interesting, but I don't have anything against it. I literally can't think of anything else to say. 5/10
- Ron/Luna: I've always had something against this ship and I can't really put my finger on what it is. Maybe it's that I've seen it paired often with Harmony. Also, I tend to headcanon Luna and gay and the only male character I really actively ship her with is Harry. 2/10
- Ginny/Draco: I used to dislike this ship but it's grown on me. I pretty heavily headcanon Draco as being gay, and Ginny is the only girl that I even remotely ship him with. Strangely, it was actually reading the Cursed Child that changed my mind about this ship. They have a pretty interesting dynamic. 7/10
- Ginny/Neville: I've always thought that this ship is really cute. They don't have many interactions in canon, but I can imagine them having a very nice relationship. 7/10
- Harry/Neville: This is another one of those ships that I don't have much of an opinion on, either negative or positive. I just find their dynamic pretty boring, to be honest. Still, there's nothing I actively dislike about the ship. 5/10
- Luna/Draco: No. No no no. I don't know why, this ship just freaks me out. I don't like thinking about it or hearing about it. No. 0/10
- Ginny/Luna: I don't care what anyone says, this is the best Harry Potter ship and I will defend it to my death. Ginny and Luna are perfect for each other. Ginny's one of the only people who I think can really understand and appreciate Luna, and Luna is the best person to complement and support Ginny's strength. I will forever be upset that we didn't get any more scenes of these two interacting in canon. But that's what fanfiction is for, I guess. 10/10
- Harry/Ron/Hermione: I'm obviously a fan of the golden trio. Who isn't? The idea of their relationship being romantic is pretty interesting, but I generally prefer them as friends. 5/10
- Harry/Ron/Luna: Not really my thing. In a poly ship, it's kind of necessary to like all the individual relationships between characters, and the only individual relationship I find interesting in this ship is Harry and Luna. 4/10
- Harry/Ron/Draco: This is one of the most common Harry Potter OT3s that I've seen. I personally don't find it that interesting. 4/10
- Harry/Hermione/Ginny: As I don't particularly ship any of the three combinations of characters, this ship is not one of my favourites. 4/10
- Harry/Hermione/Draco: I feel like this should be a really popular OT3 given how popular all three ships within it are, but I guess Harmony, Drarry and Dramione shippers are generally very different people. I can't say that I'm a particular fan of the poly ship. I don't think Hermione works romantically with either of them. 3/10
- Harry/Ginny/Luna: This is one of, if not my number one, favourite HP poly ship. I enjoy all the individual dynamics, and I think they would all work really well in a relationship together. 8/10
- Harry/Ginny/Draco: This is another one of my favourite poly ships. Again, it was weirdly Cursed Child that got me shipping these three. I'm not saying that this would be a healthy relationship, but it would be very interesting. 7/10
- Harry/Luna/Draco: No. I'm just too opposed to Luna/Draco to even consider this. 1/10
- Hermione/Ginny/Luna: A femslash OT3! I can't say this is one of my favourites, but I don't dislike it. 6/10
- Hermione/Ginny/Draco: I feel like this ship inherently focuses too much on Draco for my liking, and I just really dislike Dramione. 3/10
- Neville/Ginny/Luna: This is one of the best poly ships out there! Not only is it really adorable, it also totally works with canon. I've always been interested in reading a take on the events of Deathly Hallows from the perspective of these three. 8/10
- Harry/Hermione/Ginny/Draco: This is the most common 4 person poly ship I've seen in the fandom. I really like some of the dynamics between these characters, but I dislike others. 5/10
- Harry/Neville/Ginny/Luna: This ship combines two of my favourite OT3s, Harry/Ginny/Luna and Neville/Ginny/Luna. This is the only four person combination within the big seven in which I do not dislike any of the individual relationships. 7/10
