Zodiac Compatibility Calculator

Compare any two zodiac signs

Select your sign and your partner's sign, then calculate. All twelve signs are available, including same-sign pairs. No names, dates, or account are required. This is a sign-pair game; it does not calculate your Sun sign from a birthday.

How zodiac compatibility is calculated

This calculator uses a fixed sign-pair table. It looks up your selected pair, then checks the reverse order if needed. Pairs without a listed value receive a default score of 75%. Choosing the same pair again gives the same result, and switching the signs gives the same score.

The communication score adds 2 points to the overall score, and romance adds 4, each capped at 100%. Emotional connection subtracts 2 points, with a minimum of 60%. These category scores follow the formula; they are not separate assessments.

For example, Aries and Leo receive 92% overall, 94% for communication, 96% for romance, and 90% for emotional connection. These numbers come from the table and adjustments, not from information about the two people.

Read a listed pair and a fallback pair

Aries and Taurus have no listed pair value, so the overall result is the 75% fallback. Applying the same adjustments gives 77% communication, 79% romance, and 73% emotional connection. The four numbers describe one lookup and its arithmetic, not four independently discovered traits.

A shared element does not determine the table value: Aries with Aries receives 82%, while Leo with Leo receives 84%. Both are same-sign fire pairings. Our guide to zodiac elements explains the traditional grouping separately from this game's scores.

What does your result mean?

Use it as a light conversation starter. The percentages are not scientifically validated and do not measure how well two people will get along. A 75% default is simply a table fallback, not evidence about your relationship.

A sign comparison does not include birth time, planets, houses, or a full birth chart. For a different perspective, explore our limited birth chart comparison or read about zodiac elements.

Start a real conversation

Ask each other what helps you feel heard, how you prefer to work through disagreements, and which gestures of care matter to you. Our love language test can help you reflect on those preferences.

Zodiac compatibility questions

Is this based on Sun signs or a full birth chart?

It compares the two sign labels you choose, usually your Sun signs. It does not use Moon signs, birth times, or planetary aspects. Read Sun sign vs. birth chart compatibility to compare the approaches.

Why do several pairings show 75%?

Pairs without an entry in the table use the same 75% fallback. That shared number does not mean those relationships have equal strengths or challenges.

Can the same zodiac sign be a good match?

You can compare two people with the same sign here, but neither a shared sign nor its score establishes a good match. Ask about the person's actual preferences instead of assuming they fit a sign description.

Will another zodiac calculator give the same percentage?

It may not. Other websites can use different tables or scoring rules. There is no universal zodiac compatibility percentage, so compare the stated methods before treating two results as equivalent.

Does today's horoscope change this result?

No. This form uses only the two selected signs. It does not use today's date, current transits, names, or relationship history. Repeating the same pair under the current table gives the same result.
