Zodiac compatibility calculator

Pick your sun sign and theirs. Vela shows how the two temperaments meet: what flows easily, where the friction tends to live, and a question worth sitting with. Never a compatibility percentage, because a real bond is not a number.

What sun-sign compatibility is, and isn’t

Your sun sign is the core you are growing into, so two sun signs meeting is a real and readable thing: two ways of wanting, resting and reacting, side by side. It is a genuine doorway. What it is not is a percentage, a grade, or a verdict on whether a relationship will last. Vela never gives you those, on purpose. The point is not to be told; it is to be handed something honest to reflect on.

Want to browse instead? See every sign pairing, or find your other placements with the moon sign calculator and the rising sign calculator: the Moon and Rising shape how two people actually feel together at least as much as the Sun does.

Frequently asked

How do you calculate zodiac compatibility?

Vela does not reduce it to a percentage. Pick your sun sign and theirs, and we show how two temperaments actually meet: what flows easily, where the friction tends to live, and a question to sit with. It is a reflective starting point, never a score or a verdict.

Is sun-sign compatibility accurate?

Sun signs are one placement out of many. They are a genuine starting point, but two whole birth charts read together, moon signs, rising signs and where the planets fall, say far more than sun signs alone. Treat any single-placement reading as a doorway, not the whole room.

Which star signs are most compatible?

There is no universal best match. Signs that share an element often feel easy together; signs that challenge each other often grow each other, and ease and depth are not the same thing. Each pairing reading names both the flow and the friction, so you can decide what you actually value in a bond.

Is the compatibility calculator free?

Yes, and no account is needed. For the deeper version, a Vela membership reads two full birth charts together, your real placements rather than sun signs alone, still as reflection and never as a score.
