An MBTI compatibility chart for all 16 types: how many letters each pair shares, what each difference means, and what research says matters more than type.
The Myers & Briggs Foundation says “there are no best or more successful combinations of types in relationships.” Research on couples points the same way. In national samples from Australia, the UK and Germany, how alike two partners' personalities were explained less than 0.5% of how satisfied they were with the relationship.
Each number is how many of the four letters two types share. Sharing letters tells you where things come easily and where you will need to talk. It says nothing about how happy you will be.

| Letter pair | If you share it | If you differ |
|---|---|---|
| E / I | Both recharge around people. Both recharge alone or with a few people. | One recharges with people, the other alone. Agree on how much social time each of you needs. |
| S / N | Both start from facts and specifics. Both start from patterns and possibilities. | One starts from facts and details, the other from patterns and possibilities. When you plan together, say which one you are offering. |
| T / F | Both lead with logic when deciding. Both weigh how people will be affected. | One decides with logic first, the other with people first. In a disagreement, name which one you are arguing from. |
| J / P | Both like things settled. Both like to keep options open. | One likes things settled, the other likes options open. Agree early on what needs a plan and what can stay loose. |
Type-theory descriptions of each letter, not research findings about couples.
The largest study of this, across national samples in three countries, measured partners on the Big Five traits. Each person's own personality explained about 6% of their relationship satisfaction. Their partner's explained 1 to 3%, mostly through being agreeable, conscientious and emotionally stable. How similar the two were explained less than 0.5%.
A 2020 study pooling 43 couple datasets found the strongest predictors were about the relationship itself, such as how committed and appreciative people felt their partner was.
| Your own personality | about 6% |
| Your partner's personality | 1 to 3% |
| How alike you are | under 0.5% |

Many charts online give each type a “natural partner”. One of the earliest, on PersonalityPage.com from at least 2000, built the pairs from a rule: the same leading mental process, turned the other way, with J and P swapped. That rule is how INTJ ends up matched with ENFP or ENTP. The site cited no study.
Other charts borrow “duality” from socionics, a separate typology from the 1970s whose letters don't mean quite the same thing as Myers-Briggs letters. Neither comes from Myers-Briggs research.

Slightly the reverse. In Isabel Myers' own data on married couples, as transcribed by Team Technology, couples who shared three or four preferences made up 44% of the sample, against 31% expected by chance. Two cautions: the chance figures assume every letter splits 50/50, which real populations don't, and the table shows who married whom, not who was happier.

No pair has been shown to be. The Myers & Briggs Foundation says there are no best or more successful combinations, and couple research finds personality similarity explains less than 0.5% of relationship satisfaction.
They share two letters, N and F, and differ on E/I and J/P. Like any pair they can get on well; the chart shows which differences to talk about.
Not much. In Isabel Myers' couples data, partners who shared three or four letters were a little more common than chance would predict.
A consultant quoted by the test publisher's consumer site said the T/F letter likely has the biggest effect. That is an expert opinion, not a study result.
From a “natural partners” rule published by PersonalityPage.com around 2000, and from socionics. Neither is based on Myers-Briggs research.
