How do you know if someone is compatible with you?

Look for aligned core values and life goals (children, location, faith, monogamy), everyday lifestyles that fit, easy communication, respectful handling of disagreements, and consistent behavior over time. You should feel attracted to them and also safe and like yourself around them. Compatibility becomes clear over weeks and months, so observe how they act in ordinary and stressful moments.

Is chemistry or compatibility more important?

Both matter, but compatibility better predicts whether a relationship can last. Chemistry creates attraction and excitement; compatibility determines whether your lives, values and ways of relating actually fit. Intense chemistry with major incompatibilities often leads to turbulent relationships, while attraction frequently grows with someone who is compatible and treats you well.

What are the biggest relationship dealbreakers?

Common dealbreakers are whether to have children, where to live, monogamy versus open relationships, marriage, the role of religion, and attitudes to alcohol, smoking or drugs. These differences are hard to compromise on without one person giving up something essential, so discuss them gently early on and more seriously as the relationship develops.

How long does it take to know if someone is right for you?

You can often tell quickly if someone is not right, but confirming that someone is right usually takes several months. Early infatuation can hide incompatibilities, so it helps to see each other in different situations, including stress, disappointment and daily routines, before making major commitments like moving in together.

Are dating app compatibility scores accurate?

They are useful as a starting point, because they show overlap in interests, lifestyle and goals, but no score can measure kindness, consistency or how you feel together. Look for apps that explain why you match, as Souldaters does with plain-language reasons, and treat a high score as an invitation to talk rather than a guarantee.

What does it feel like when it is a good match?

Many people describe a combination of attraction and calm. You feel relaxed and like yourself, conversation comes easily, you trust that they will do what they say, and disagreements get resolved without fear. Constant anxiety about where you stand is usually a sign of inconsistency or mismatch, not a sign of deep connection.

How to Know If It's a Good Match: 12 Signs of Compatibility

You know it is a good match when your core values and life goals align, your everyday lifestyles fit without constant compromise, you communicate and resolve disagreements in ways that leave both of you feeling respected, and you feel both attraction and a sense of ease around each other. Chemistry tells you there is interest; consistency, kindness and compatibility over time tell you whether it can last.

Below are the clearest signs of real compatibility, the difference between chemistry and compatibility, the questions worth asking in the first weeks, and the signals that a promising connection is not quite right.

What is the difference between chemistry and compatibility?

People often confuse the two, and it causes a lot of heartbreak.

	Chemistry	Compatibility
What it is	Attraction, spark, excitement, physical pull.	How well your values, goals, lifestyles and ways of relating fit together.
How fast you feel it	Often immediately.	Revealed over weeks and months.
What it predicts	Interest and desire.	Whether a relationship can be stable and happy long term.
Trap to avoid	Mistaking intensity or anxiety for a deep connection.	Staying with someone who fits on paper but whom you are not drawn to.

Healthy relationships generally need both. Chemistry without compatibility often produces exciting, turbulent relationships that fall apart over fundamental differences. Compatibility without any chemistry can feel like a good friendship rather than a romance. The good news: attraction often grows as you get to know someone who treats you well, while fundamental incompatibilities rarely disappear.

What are the signs someone is a good match?

1. Your core values align

Values are what you consider important: honesty, family, faith, ambition, generosity, adventure, security, justice. You do not need identical values, but the ones that matter most to each of you should not clash. A person who values financial security and a person who values spontaneity above all can work, but only if they talk about it.

2. You want the same big things

Some differences cannot be compromised without one person giving up something essential. These are the true dealbreakers:

Whether to have children (and how many).
Where to live: city or countryside, this country or another.
Monogamy or an open or polyamorous structure.
Marriage or not.
The role of faith in daily life and in raising children.
Relationship with alcohol or other substances.

These are worth raising early, lightly at first and more seriously as things develop. Souldaters lets you set dealbreaker filters, such as wanting or not wanting kids, sober only, or non-smokers, so you can screen for some of these before you even match.

3. Your lifestyles fit day to day

Everyday habits matter more than people expect: sleep schedules, diet, exercise, tidiness, social energy, how you spend weekends, how much time you want together versus apart. A vegan and a keen hunter can fall in love, but they will need to think carefully about shared meals and holidays. Our guides to dating as a vegan and health-conscious dating go deeper into lifestyle fit.

4. Conversation flows, and so do silences

You can talk easily about both silly and serious things, and you are comfortable being quiet together. You leave dates feeling energized or peaceful, not drained from performing.

5. They are consistent

Their words match their actions. They reply within a reasonable time, turn up when they say they will, and do not swing between hot and cold. Consistency is one of the most underrated signs of a good match, and one of the strongest.

6. You handle disagreement well

Every couple disagrees. What matters is how. Good signs: you can raise a concern without it becoming a fight; they listen, acknowledge your view and can apologize; disagreements end with repair rather than silence or score-keeping.

7. You feel safe and like yourself

You do not edit yourself to keep them interested. You can share opinions, quirks and vulnerabilities without fear of mockery. Your body feels relaxed around them. Feeling constantly anxious about where you stand is not "butterflies"; it is usually a sign of uncertainty or inconsistency.

8. They respect your boundaries

When you say no, to a plan, to a pace, to physical intimacy, they accept it without sulking, pressure or guilt-tripping. Respect for small boundaries early is a strong predictor of respect for big ones later.

9. You are curious about each other

They ask questions and remember the answers. They are interested in your friends, work and passions, and you feel the same about theirs.

10. Your friends and family like them (or at least see how they treat you)

People who love you can sometimes see things you do not. If trusted friends consistently raise concerns, listen, even if you ultimately decide differently.

11. You are kind to each other in small moments

A good match shows up in the ordinary: saving you the last slice of cake, texting to check you got home, being gracious to a waiter. Small kindnesses reveal character more reliably than grand romantic gestures.

12. You can imagine an ordinary life together

Not only holidays and romantic dinners, but Tuesday evenings, illness, a tight month, a difficult family gathering. If you can picture those with this person and feel okay, that is a very good sign.

What questions help you find out if you are compatible?

You do not need to interview your date. Spread these across conversations naturally, and share your own answers too:

What does a perfect ordinary weekend look like for you?
What are you working toward over the next few years?
How do you like to spend time with a partner, and how much alone time do you need?
What did your last relationship teach you?
How do you usually handle stress or conflict?
Do you want children? Where do you see yourself living?
What role do faith, health or community play in your life?
What makes you feel most cared for?

What are signs it is not a good match?

Some incompatibilities are gentle, just a lack of fit. Others are red flags. Be honest with yourself if you notice:

Persistent anxiety: you are always wondering where you stand.
Mismatched effort: you do all the planning, messaging and compromising.
Dealbreaker gaps that one of you hopes the other will "grow out of."
Contempt or mockery, even disguised as jokes.
Boundary pushing: pressure about intimacy, time, money or pace.
Different relationship goals: one wants commitment, the other keeps it vague.
You feel smaller around them: quieter, more careful, less yourself.

For a fuller list, read red flags and green flags. And remember that "not a good match" does not mean either person is bad. Often two good people simply want different lives.

Can compatibility scores on dating apps tell you if it's a good match?

Compatibility scores can be a useful starting point, because they highlight overlap you might miss when swiping on photos. They cannot measure the most important things: kindness, consistency, how someone handles conflict, or how you feel together. Treat any score as a reason to start a conversation, not as a verdict.

On Souldaters, the soul-match percentage is calculated from shared tribes, interests, diet, relationship goals, lifestyle (kids, smoking, drinking, exercise) and distance, and it shows plain-language reasons like "3 shared tribes" or "both want kids." That transparency helps you see why someone might be a good fit, so you can explore those areas together. You can read more on how it works.

How long does it take to know if someone is a good match?

You can often tell quickly if someone is not right: a dealbreaker, disrespect or no spark at all. Knowing someone is right takes longer. Many relationship counselors suggest that people show their consistent selves only after several months, once the early infatuation settles and you have seen each other stressed, tired, disappointed and in ordinary routines. Take your time before big commitments like moving in, and use the early months to observe rather than to decide.

How can shared interests help you find a good match?

Shared interests are not the same as shared values, but they help in two ways: they make it easier to meet and talk, and they give you things to do together. Joining communities around the things you love, whether that is hiking, meditation, books or veganism, puts you among people with whom a conversation starts naturally. Souldaters organizes this around tribes, and you can filter Discover to people who share at least one tribe with you. Our guide on meeting people who share your interests has more ideas.

The simplest test

After time with them, ask yourself: Do I feel more like myself, and do I like who I am around this person? If the answer is yes, and your values and life goals line up, you have the foundation of a good match. If you want to start meeting people with that in mind, you can create a free profile and let your tribes and dealbreakers do some of the sorting for you.
