Friend compatibility test: 10 questions to ask together

What does a friend compatibility test tell you?

A friend compatibility test helps two people compare what they need from friendship: contact, reliability, privacy, support and room to disagree. The ten questions below give you specific situations to discuss together. Use the answers to agree on workable habits and notice recurring friction, rather than predict how long a friendship will last.

Knowing someone's favourite takeaway is lovely. Knowing whether they want company or quiet after a bad day gives you something you can use on a difficult Tuesday.

How do you take this test with a friend?

Answer each question separately before comparing notes. Write what you would actually do, including the slightly embarrassing answer, then add a recent example where possible. New friends can use hypothetical situations and leave anything personal unanswered.

Mark each answer similar, different but workable, or needs a conversation. These are discussion labels, not a validated scoring system; adding them up would give differences a precision they haven't earned. For another example of a comparison approach without an overall percentage, Selfetti's friendship test compares individual answers.

Which questions should you ask to check friendship compatibility?

1. Contact: agree on what staying in touch looks like.

   Ask: “If we didn't speak for two weeks, would you feel comfortable, worried or forgotten?” One person might send daily updates while another saves everything for a Sunday call, so name your preferred rhythm and what a delayed reply means to you. Try: “I often read messages at work and forget to reply; ring me if something needs an answer today.” A workable agreement leaves room for busy weeks without making either friend guess whether the friendship has quietly ended.

2. Reliability: decide how to handle changed plans.

   Ask: “If you needed to cancel an hour before meeting, what would you do next?” Compare how much notice you need, whether you'd expect an explanation, and who should suggest another date. Someone with unpredictable shifts may need flexible arrangements, while someone arranging childcare needs a firmer commitment. Try agreeing: “If either of us cancels, that person suggests the next plan”; then notice whether the agreement survives beyond this conversation.

3. Money: make an affordable plan easy to suggest.

   Ask: “If our group picked a restaurant you couldn't comfortably afford, would you say so?” Discuss splitting bills, lending money and whether birthdays come with an expectation of gifts, because those costs can turn a casual invitation into something difficult to answer. A useful script is: “I've got £15 for tonight; could we get lunch instead?” Compare whether that suggestion gets an easy yes, a sensible alternative or pressure to spend more than you wanted.

4. Social energy: make room for different kinds of company.

   Ask: “Would your ideal Saturday together involve just us, a small group or meeting lots of people?” Different answers can work if invitations leave room for both preferences, including leaving a gathering at different times. A quieter friend might enjoy an hour at a party but resent being persuaded to stay until midnight. Suggest a specific compromise: “I'll come for dinner, then head home; you can stay out with everyone else.”

5. Support: ask what helps before offering a solution.

   Ask: “When you've had a terrible day, do you want listening, advice, distraction or practical help?” Work through an ordinary example, such as missing a deadline, because “I'll always be there” doesn't explain what either person would find useful. Try: “Would you like to talk, work out what to do, or have some company while you cook?” If you need more prompts, these questions for getting to know someone can help a conversation move beyond favourite films.

6. Disagreement: find a way to pause and return.

   Ask: “If something I said upset you, when and how would you want to raise it?” One friend may want to clear the air immediately while another needs time to find the words; discuss how each person can ask for that time. Try: “I'm upset and need tonight to think, but I'll call tomorrow after work.” The practical check is whether both friends return to the conversation and address what happened, including an apology or changed behaviour where needed.

7. Privacy: be specific about what stays between you.

   Ask: “Could I repeat something you told me to my partner or another close friend?” Include photographs, screenshots and group-chat stories, since a harmless anecdote to one person might feel exposing to the person in it. Try: “You can mention that I'm changing jobs, but please keep the reasons private.” If a confidence has already been shared, discuss what happened and what needs to change before handing over another sensitive detail.

8. Boundaries: check how a clear no is received.

   Ask: “If I couldn't lend you money or host you overnight, how would we handle that?” Choose a situation that carries some inconvenience, because agreeing that boundaries matter is easier than accepting a disappointing answer. A reply such as “I'm disappointed, but I'll make another arrangement” leaves space for feelings without repeated bargaining. Notice whether saying no leads to guilt, ridicule or punishment; matching hobbies won't resolve that behaviour.

9. Change: leave room for a friend's separate life.

   Ask: “If one of us moved, started a relationship or became a parent, what would we hope to keep?” Name a manageable habit, such as a monthly walk or an occasional call, rather than promising that nothing will change. Friends living apart can choose ways to stay connected over distance around their actual schedules. Also ask how you'll respond to good news when one person's progress touches something the other person is struggling with.

10. Expectations: name the friendship you each want.

    Ask: “Are you hoping for an occasional activity friend, a close confidant, or something in between?” Someone can be excellent company at badminton without wanting late-night emotional conversations, and naming that difference helps you choose what to expect. If romantic feelings are making the answer difficult, a friends-or-something-more quiz can offer prompts, though you'll still need to ask the person directly. Neither warmth nor a strong match on these questions tells you whether someone wants to date.

What if your answers are very different?

Read each “needs a conversation” answer aloud and choose one small agreement to try. For example: “Let's choose the price before booking” is specific enough to follow through on. Revisit the agreement after the situation happens, using what each person actually did.

A different preference leaves something to discuss. Repeatedly ignoring an agreement gives you different information: your friend now knows what matters to you and still isn't respecting it. You can reduce what you rely on that friendship for without turning the exercise into a verdict on someone's entire character.

The short version

• Answer separately, then compare real examples rather than ideal versions of yourselves.
• Discuss contact, plans, money, support and boundaries before assigning meaning to differences.
• Choose one practical agreement and notice whether both friends keep it.
• Leave room for different preferences while taking repeated disrespect seriously.
