How do the 12 signs match on a zodiac compatibility chart?

A zodiac compatibility chart shows how all 12 signs match each other, based on the distance between them around the zodiac. Find one sign down the side and the other across the top, and the square tells you whether the pair is Strong either way, Easy, Tense or has Little in common. Enter two birth dates in the form for a closer look at both full charts.

On a zodiac compatibility chart, each pair of signs falls into one of four groups, depending on how many signs apart they sit. The same sign is Strong either way, two or four signs apart is Easy, three or six apart is Tense, and one or five apart has Little in common. A Sun sign is only one part of a chart, so the birth date form goes further.

How to use it

  1. Enter both birth dates Enter a month, a day and a year for both people. Once you fill in one box, the cursor moves on automatically to the next one. When you know the hour and city you were born in, enter both; if you don't, tick the unknown-time checkbox instead.
  2. Choose Couple or Friends or family Pick the type of relationship you want to look at. When one of the two people is younger than 18, you can pick only Friends or family, which keeps the reading suited to them.
  3. Press the button Your browser does the math itself, and you then land on a results page showing the outcome. No account, name or email is needed, and the birth dates are not placed in the page address.
  4. Read the connections Look over the totals for Easy, Tense and Strong either way links, the most powerful connections, and a short one-line interpretation for every aspect. Compare them with what the sign chart suggested.

Who reaches for a sign chart

Most visitors arrive with a quick question and two signs in mind. Someone has just met a person at a friend’s party and wants a light talking point. A new manager wonders why a teammate’s way of working feels so different. Two siblings planning a trip want to see who is likely to pull in the same direction. A sign grid answers each of these in a glance, and nothing needs to be typed.

People also use the grid as a warm-up. They look up the pair first, notice the group it falls into, and then enter the birth dates to see whether the fuller picture agrees or adds something new.

Count the distance yourself

The signs run in a circle: Aries, Taurus, Gemini, Cancer, Leo, Virgo, Libra, Scorpio, Sagittarius, Capricorn, Aquarius, Pisces, and then back to Aries. Count both ways round the circle and use the shorter count, so Aries and Capricorn are three apart.

A few quick counts show the method. Aries and Taurus are one sign apart. Aries and Gemini are two apart. Aries and Cancer are three apart. Aries and Leo are four apart. Aries and Libra sit directly across the circle, six apart. Once the count is clear, the group follows: two or four apart is Easy, three or six apart is Tense, one or five apart has Little in common, and the same sign is Strong either way.

The five aspects: conjunction is strong either way, sextile and trine are easy, square and opposition are tense

What each group means in the angles

The groups come from the classic angles between planets. Here they are counted by sign. The birth date form uses exact degrees, so two people with the same sign may not have a conjunction.

Strong either way

Two people with the same sign share a conjunction. Their themes blend into one, and they tend to feel the same energy together and strongly. Whether that feels easy or demanding depends on which planets are involved, so the group is named Strong either way instead of good or bad.

Easy

Signs two apart form a sextile, a friendly and cooperative link. Think of an open door: the chances are there, but someone has to walk through. Signs four apart form a trine, an easy and flowing link. A trine frequently points to innate gifts, though the downside is that things coming easily may leave you taking them for granted.

Tense

Signs three apart form a square, which feels like two people pulling in different directions. The tension can be uncomfortable, and it is also what pushes people to decide and act. Signs six apart form an opposition, like the two ends of a seesaw. The work there is balance: honoring both needs instead of choosing only one.

Little in common

Signs one or five apart do not form one of these classic angles. The grid marks them as Little in common, which means the sign pair offers no strong shared theme of its own. Other parts of the two charts can still connect.

Using the Easy and Tense lists under the grid

Below the grid, each sign lists its Easy and Tense signs. This is the quickest way to scan a whole friend group or a household. Pick the sign you know best, read down the two lists, and see where the people around you fall.

A workable habit is to read the Tense list as a set of places where you may need a little more patience or a clearer agreement, and the Easy list as a set of places where cooperation may come without much effort. Neither list is a ruling on a person. A Tense pair can build a steady working routine, and an Easy pair can drift if neither side puts in effort.

Reading signs beside their themes

The sign keywords help the grid come alive. Aries brings initiative, courage and independence. Taurus brings steadiness, patience and comfort. Gemini brings curiosity and communication. Cancer brings nurturing, sensitivity and a sense of home. Leo brings confidence, generosity and creativity. Virgo brings precision and practicality. Libra brings balance, fairness and diplomacy. Scorpio brings intensity, depth and privacy. Sagittarius brings optimism, freedom and honesty. Capricorn brings ambition, discipline and responsibility. Aquarius brings originality and independence. Pisces brings compassion, imagination and intuition.

Every sign also has a shadow side: impatience, stubbornness, restlessness, pride, perfectionism, indecision, control, reserve, detachment, escapism. When you look at a pair, ask which keywords of each sign you see in the real person, and where the two sets might rub or support each other. The answer is a conversation starter, not a conclusion.

Preparing the details for the closer comparison

The birth date is enough to start. For a richer reading, gather the birth time and the birth city as well. A birth certificate often lists both, and a parent or older relative often remembers the hour.

Type the city of birth, not the city where the person lives now. Each entry in the dropdown gives a city, region and country, so choose the one that fits. If the time is not known for either person, tick the unknown-time box and leave the city out; the comparison still runs from the dates.

Scenes where the closer result earns its place

Two friends who share an Easy sign pairing may still wonder why some evenings feel out of step. Once both complete birth dates are in, you get every aspect linking the two charts along with its orb in degrees, which lets you tell tight connections from looser ones.

A couple on a Tense sign pairing might open the strongest connections and find several Easy ones among them. The sign grid told one part of the story, and the full list adds the rest.

Family groups can use the Friends or family view as well. A parent and teenager can enter their dates together and read the one-line meaning of each aspect aloud, taking turns choosing which one to talk about.

Keeping the reading in proportion

Use the chart for reflection and conversation. Notice which results make you nod and which feel off, and let the second group teach you as much as the first. A sign pairing offers a theme to think about, and the people involved decide what to do with it.

Common questions

What does a zodiac compatibility chart show?

A zodiac compatibility chart shows how each pair of the 12 signs relates by distance around the zodiac. Every pair is marked Strong either way, Easy, Tense or Little in common. Below the grid, each sign lists its Easy and Tense signs, so you can scan one sign against all the others.

How is zodiac compatibility calculated here?

The chart counts the signs between the two. Same sign is Strong either way. Two or four signs apart is Easy, three or six apart is Tense, and one or five apart has Little in common. The birth date form goes further and compares two full birth charts, with orbs in degrees for each aspect.

Can I check compatibility by birth date?

Yes. Enter two birth dates in the form and the result compares both full charts, not only the Sun signs. Birth time and city are optional. If you add a time, rising signs and houses are included in the comparison, along with house overlays and a composite chart.

Can incompatible signs have a good relationship?

Yes. A Tense pairing means friction, and friction can push two people toward decisions and action. Many astrologers see squares as the places where people do the most growing. The birth date form also shows other links between the two charts, including Easy ones.

What is the difference between sun sign compatibility and synastry?

Sun sign compatibility compares only one sign per person. Synastry lays two full birth charts over each other and checks the angles between planets, such as Moon, Venus and Mars. The sign grid gives a quick first look, and the birth date form gives the closer answer.

Is there a compatibility percentage?

The sign grid uses four groups, not a percentage. Your result gives scores for attraction, talking, feeling and staying, plus tallies of the Easy, Tense and Strong either way connections. Those numbers are there to read and reflect on, for entertainment and personal reflection.

Do I need an account or my name?

No. The form asks for birth dates only, with optional time and city. It does not ask for a name or gender. Every calculation, plus the single-line interpretation for each aspect, costs nothing, and you never need an account or an email address.

Does it work for friends and family, not only couples?

Yes. You can toggle your results from Couple to Friends or family and back. If either person is under 18, you can pick only Friends or family as the relationship type. Pick the one that matches the relationship you want to look at, then read the connections as usual.
