♈︎ Aries + ♌︎ Leo
90% · Trine (same element)
Same element, so you speak the same emotional language without translation. Trines are the traditional best match: ease, understanding and shared values. The risk is coasting and never challenging each other.
Two fire signs bring enthusiasm, courage and a lot of heat; keep an eye on ego clashes. Aries is cardinal and Leo is fixed, so you handle change differently (starting versus sustaining).

Beyond Sun signs
Two people with “incompatible” Sun signs can have a Moon in each other’s Sun sign or Venus trine Mars, which counts for more. If you know both birthdays, the synastry chart calculator compares every planet, and the composite chart describes the relationship as a whole.
Questions people ask
How does zodiac compatibility work?
Sign compatibility is based on the angle between two signs around the wheel. Signs of the same element (120° apart, a trine) are traditionally the easiest match, compatible elements 60° apart (sextile) are friendly, opposite signs attract, and signs 90° apart (square) create friction.
Which zodiac signs are most compatible?
By the classical rules, same-element pairs: fire (Aries, Leo, Sagittarius), earth (Taurus, Virgo, Capricorn), air (Gemini, Libra, Aquarius) and water (Cancer, Scorpio, Pisces). Fire also pairs well with air, and earth with water.
Is Sun sign compatibility accurate?
It’s a starting point. Sun signs describe only one planet. Astrologers look at the Moon, Venus, Mars and Ascendant between two full charts, which is what our synastry calculator does.
What do the percentages mean?
They’re a simple traditional score for the angle between the signs (trine highest, quincunx lowest). They describe how easy the signs find each other, not how good a relationship will be.
