Aries + Leo Compatibility
Double flame, fast, loud, and alive: 84% overall match (love 86%, friendship 91%, communication 80%, long-term 77%).
Two fire signs move at the same speed: fast. Attraction is instant, plans are spontaneous, and the energy in the room doubles when you are both in it. The risk is that fire needs fuel, if the relationship becomes routine, one of you will light a fire somewhere else, and neither of you naturally plays the calm one during a fight.
For a woman and a man
Aries and Leo is Mars with the Sun, fire with fire. The Aries is cardinal and wants to begin, and the Leo is fixed and wants to keep what it builds. There is a lot of warmth here, a lot of play and a fair amount of pride, and it belongs to both of you, not to whoever is the man.
The friction comes when you both want the credit. A dinner party goes well and you each tell the story of how you pulled it off. The Leo wants to be appreciated, the Aries wants to be first, and small competitions start to pile up: who chose the restaurant, who planned the trip, who made the call that worked.
This pair does best when praise is spoken out loud and often. The Sun runs on recognition, and Mars runs on a fresh challenge. Give the Aries the launches and the Leo the long-running projects that need loyalty. Then take turns in the spotlight on purpose. Two fire signs can keep each other warm for decades if neither has to fight for the light.

For two women
Aries and Leo is Mars with the Sun, two fire signs, one cardinal and one fixed. In a couple of women there is no inherited rule about who gets the lead, so the chart decides, and both of you have a claim. The Aries starts things. The Leo holds on to them and expects applause.
That sounds like a good partnership, and often is, but you both want to be the centre of the room at the same moment. At a friend's birthday, the Aries is telling the story of the trip and the Leo cuts in to tell it better. Neither is being unkind. Each just believes the story is theirs. Then the argument that follows, in the car, is fast and loud, and neither will step down first because stepping down feels like losing.
Build in turns. Agree that one of you tells the story and the other holds the stage next time, and say thank you out loud, because Leo needs to hear it and Aries likes being thanked for speed. When a row begins, let the Aries have the first word and the Leo the last, then laugh. You both warm up quickly.

For two men
Two men, Aries and Leo, make a hot and proud match: Mars and the Sun, both fire, cardinal beside fixed. No automatic rule says who leads, so your signs fill the gap. The Aries is faster off the mark. The Leo is steadier, more loyal, and more set on how things should look once they are done.
Both of you want to be in the spotlight, often in the same minute. Think of a dinner you are hosting. The Aries is carving the meat before guests sit, the Leo is topping up wine and telling the best story, and each has a slightly different idea of whose evening it is. It is fine until it is not. When a disagreement starts, it climbs quickly, because neither of you cools it down.
The fix is generous rather than clever. Give each other a stage. Let the Leo host and be seen, and let the Aries start and finish the project. Say well done to each other without being asked. The pair stays bright when each of you is the audience as often as the act, and Leo especially gives back what it gets.
With a non-binary partner
With a non-binary partner, Aries and Leo can be a proud, loyal pair. Leo, ruled by the Sun, wants to be seen as they truly are, and wants the people they love to say it out loud. Aries, ruled by Mars, will happily say it, loudly if need be. That is a real strength when it comes to names, pronouns and how you describe each other in public.
The difficulty is that both signs like to be in front. If the Leo is the non-binary partner, they may want to shape how you are introduced, and the Aries, who jumps in, may speak first and get it slightly wrong. If it is the Aries, they will not wait for permission and may speak for you both. Either way, a sharp exchange follows and neither will give way easily.
Before the next gathering, decide together who says what. One of you introduces the other, using the agreed words, and the second gets to add the funny detail. It gives each of you a moment in the light, with the right names used. After that, enjoy the party. Neither of you is the supporting act.

For Aries and Leo, the Venuses fall in an easy aspect in 19.6% of birthday pairs, below the 22.8% average, and the Mercuries in 21%, below the 22.7% average. Venus and Mercury stay close to the Sun, so these are the figures your Sun signs really do move.
The Moons get on in 22.8% of pairs, against 22.2% across every pairing. The Moon can be anywhere on any birthday, so the Sun signs say almost nothing about it: whether your Moons get on is in your two birth charts, not in your Sun signs.
