Gemini and Leo compatibility
Gemini and Leo are two signs apart on the wheel, a sextile of about 60°: air and fire, one mutable and one fixed. Astrology reads the angle between two Sun signs as the first measure of a pair, and the rest of the two charts as the rest of the story.
This year the Sun is in Gemini from 21 May to 21 June and in Leo from 22 July to 23 August. 6 famous couples in StarMap's dataset are a Gemini and a Leo, where chance would give about 9: Madonna and Tupac Shakur, Angelina Jolie and Billy Bob Thornton and Helen Mirren and Liam Neeson among them. Among the 537 couples with both Sun signs certain, that makes this the 42nd most common pairing of the 78. A Sun sign is one placement of ten, and the two whole charts say far more than the two signs.
Each sign has its own page: Gemini and Leo, with its dates to the minute, its traits and the famous people born under it.
What astrology reads for Gemini and Leo
Two signs apart is the sextile, and astrology reads it as the angle of easy conversation. The signs belong to elements that feed each other, fire with air or earth with water, so the two people tend to want compatible things without wanting the same thing. The tradition reads the pairing as friendly first: it is the angle most often found between people who liked each other before anything else was decided.
Because the sextile asks little, it is also the angle the tradition says can be left to drift. There is no friction to work against and no mirror to look into, so the relationship tends to be as warm as the attention it is given. Astrologers read it as an opportunity rather than a pull, and look to the rest of the two charts for whatever holds the pair together when the conversation stops.
Air with fire
Fire with air is read as the pairing that feeds itself: air gives fire room to burn and fire gives air something to be excited about. The tradition reads these two as talkative, restless and fast, good company for each other and inclined to keep moving rather than settle. The reading's question is where the stillness comes from, since neither element supplies much of it.
Mutable with fixed
One sign is fixed and one is mutable, a keeper with an adapter. In the tradition the fixed sign gives the relationship its shape and the mutable sign its give; the strain is read as each mistaking the other's nature for a choice, the fixed sign taking flexibility for drift and the mutable sign taking steadiness for refusal.
These are readings of the Sun signs alone, written for reflection and entertainment. They describe tendencies the tradition assigns to an angle, not two people, and they do not say whether a pair lasts.
Gemini in love, Leo in love
Gemini
In love, Gemini wants to be interested first and interesting second. Talk is the real intimacy; silence worries it. The sign is drawn to partners who keep it guessing and bored by those who do not. Its lesson is that staying can be as lively as leaving, if the conversation keeps going.
Leo
In love, Leo is romantic in the old sense: grand gestures, open admiration, a wish to be adored and to adore back. It needs appreciation the way other signs need space. Its lesson is that affection shown quietly counts too, and that a partner is not an audience.
485 famous people have the Sun in Gemini for certain and 520 in Leo: every Gemini Sun and every Leo Sun, each with a birth chart.
Famous Gemini and Leo couples
Of the 537 spouse and partner pairs in StarMap’s dataset whose Sun signs are both certain, 6 are Gemini and Leo. From the share of each sign among every couple’s members, chance alone would give about 9, a ratio of 0.66, which makes this the 42nd most common pairing of the 78. Their sky match, from the angles between the two charts, averages 73 out of 100 against 67 for every couple counted. With about seven couples a cell, a ratio between a half and double is what chance produces; the counts describe the dataset, not the signs.

Both signs in one chart
The two signs also meet inside one chart, when the Sun is in one and the Moon in the other. Astrologers read a Sun and Moon two signs apart the way they read the two Suns above, as a sextile between how a person is seen and how they feel.

Questions people ask
Are Gemini and Leo compatible?
By Sun sign alone, astrology reads Gemini and Leo as a sextile, two signs apart: air and fire, mutable with fixed. That is a reading of one placement of ten and not a verdict on two people. In StarMap's dataset of famous couples, 6 are Gemini and Leo, against about 9 that chance would give, a ratio of 0.66. The angles between two whole charts, Moon to Moon and Venus to Mars among them, say more than the Sun signs can; the comparison is free on StarMap.
How many famous couples are Gemini and Leo?
6 of the 537 couples in StarMap's dataset with both Sun signs certain, Madonna and Tupac Shakur, Angelina Jolie and Billy Bob Thornton and Helen Mirren and Liam Neeson among them. Chance alone would give about 9, which makes it the 42nd most common pairing of the 78. Their sky match, from the angles between the two charts, averages 73 out of 100 against 67 for every couple counted.
Who has the Sun in Gemini and the Moon in Leo?
26 people in StarMap's dataset have the Sun in Gemini and the Moon in Leo, Paul McCartney, Clint Eastwood and Jacques Cousteau among them. 23 people in StarMap's dataset have the Sun in Leo and the Moon in Gemini, Jennifer Lawrence, Romano Prodi and Kate Beckinsale among them. The Moon's sign depends on the day and often on the hour of birth, so only people whose Moon sign is certain are counted.
Sun signs are computed from the Sun’s position with the astronomy-engine ephemeris, checked against Swiss Ephemeris, in the tropical zodiac. Birth data and relationship data come from Wikidata; birth times, where StarMap has one, from Astro-Databank with their Rodden rating. A couple is counted only when the Sun was in one sign for the whole of each birth date. Readings describe what the tradition assigns to an angle, for entertainment and self-reflection; StarMap predicts nothing. Compare two whole charts.
