Compatibility Test
A confidential reflection tool for two people, built on the domains that couples researchers study most: communication, conflict, shared values, intimacy, finances, and roles. It shows where you already align and where there is room to grow, with an instant plain-language result and an optional in-depth report to talk through together or bring to a couples therapist. It measures fit, and fit is something you build.
Compatibility Test is a free, confidential 18-question self-assessment, informed by ENRICH and Gottman research. It takes about 5 minutes, runs entirely in your browser, and gives you a plain-language score across 3 interpretation bands plus an optional in-depth report. It is an educational screening, not a diagnosis.
Compatibility is not one thing, and it is not fixed
Most compatibility quizzes ask about star signs or favorite colors and hand you a made-up percentage. This tool is different. It looks at the six areas that decades of couples research, including the ENRICH inventory and John Gottman's studies, connect to how partners actually get along. None of these are set in stone, which is the whole point.
Six domains of fit
Communication, conflict resolution, shared values and goals, intimacy and affection, finances and practical life, and roles and expectations. These are the areas established couple assessments return to again and again.
One clear compatibility picture
Your answers combine into a single alignment score and a domain-by-domain breakdown. It is a map of where you fit and where you differ, not a pass or fail grade on the relationship.
Compatibility you can build
The research is encouraging: the habits that raise compatibility, like listening well, repairing after conflict, and talking openly about money and expectations, are learnable. A low area is a starting point, not a life sentence.
| Feature | Typical free quiz | Psychology.com |
|---|---|---|
| Grounded in couples research | No, novelty quizzes | Yes, ENRICH & Gottman domains |
| Covers the six domains of fit | One vague score | Communication, conflict, values, intimacy, money, roles |
| Domain-by-domain breakdown | No | Yes, see where you align and differ |
| Designed for both partners | Rarely | Yes, take it separately and compare |
| Treats compatibility as buildable | Fixed percentage | Yes, with evidence-based next steps |
| Clinician-reviewed interpretation | Rarely | Yes, reviewed |
| Confidential (no data sent) | Often tracked | Runs in your browser |
How scoring works
Answers are scored 0–72 in total. Your result falls into one of 3 bands:
| Score | Band | What it suggests |
|---|---|---|
| 0–35 | Real differences to work through | Your answers point to meaningful friction across several domains. That is worth taking seriously, and it is also workable, because most of what shapes compatibility can be learned and changed. |
| 36–53 | A promising mix with room to grow | You align well in some domains and differ in others. That is the most common place to land, and it is a solid foundation to build on. |
| 54–72 | Strong alignment across domains | You rated most areas as strongly aligned. Your answers describe a relationship that fits well across the domains couples research cares about most. |
Methodology & sources
This is an educational reflection tool, not a validated instrument, and it is honest about that. No single scientifically validated compatibility test exists, so rather than invent a formula, we built the questions around the domains that established couple assessments actually measure. The six areas, communication, conflict resolution, shared values and goals, intimacy and affection, finances and practical life, and roles and expectations, map to the domains in the ENRICH Marital Inventory (Fowers & Olson, 1989) and to the patterns John Gottman documented in decades of observational research on what helps couples thrive (Gottman & Silver, 1999). Each domain carries three plain-language statements answered on a five-point agreement scale, and the engine sums them into an overall alignment score out of 72 plus a breakdown by domain.
Read the result as a conversation starter, not a verdict on your relationship. Compatibility is not a fixed trait that you either have or do not; it reflects skills, habits, and choices that both partners can shape over time. For the best picture, take it separately from your partner and compare where your answers line up and where they diverge, because a difference one of you feels strongly and the other has not noticed is often where the most useful conversation begins. This tool asks about fit across domains. If you want to know how happy you feel in the relationship right now, that is a different question, and our <a href="/tests/relationship-satisfaction">Relationship Satisfaction Test</a> is built for it. If you are trying to name your feelings for someone, see our <a href="/tests/am-i-in-love">Am I in Love? Test</a>.

Compatibility Test FAQ
What makes two people compatible?
Research on couples points less to shared hobbies or personality matches and more to how well partners fit across a handful of everyday domains: how they communicate, how they handle conflict, whether their values and goals point the same way, how they connect physically and emotionally, how they deal with money and practical life, and whether their expectations of each other line up. This test looks at those six areas. Importantly, compatibility in these domains is shaped by habits and skills, so it can grow.
Is compatibility fixed, or can it change?
It can change, and that is one of the most useful things to know. Some differences are real and worth respecting, but most of what we call compatibility comes down to skills like listening, repairing after an argument, and talking openly about money and expectations. Gottman's research found that the couples who do well are not the ones who never disagree; they are the ones who handle differences well. A lower score in a domain marks where attention would help most, not a permanent mismatch.
How is this different from your other relationship tests?
This compatibility test is about fit across domains for two people. Our <a href="/tests/relationship-satisfaction">Relationship Satisfaction Test</a> measures something different: how happy and content you feel in the relationship right now, scored against a validated research cutoff. And our <a href="/tests/am-i-in-love">Am I in Love? Test</a> explores your own feelings, whether what you feel leans toward deep love, infatuation, or companionship. Compatibility, satisfaction, and love are related but distinct, so it is common to score differently on each.
Should both of us take it?
Ideally, yes. Take it separately and then compare your answers side by side. The most valuable insight often comes from the gaps, a domain where one of you feels strongly and the other had not registered a problem. That difference is not a red flag; it is exactly the kind of thing worth talking about calmly, and it is far easier to discuss with a shared, blame-free starting point in front of you.
Does a low score mean we are wrong for each other?
No. A low or mixed score means there are areas of friction worth attention, not that the relationship is doomed. Plenty of strong, lasting couples would have scored low early on and built their compatibility over time. Treat a low domain as information about where to focus, and if the same friction keeps returning, a couples therapist can help you work through it.
Is this test confidential?
Yes. It runs entirely in your browser. Your answers are never sent to a server, never stored, and never linked to you. No account is needed, so you can take it, and retake it with your partner, in private.
