How Many Hours Does It Take to Make a Friend? What the Study Found

You may have seen the claim that friendship takes a precise number of hours. The more useful finding is less tidy: time together is associated with growing closeness, but what people do and talk about during that time also matters. A study by communication scholar Jeffrey Hall helps explain why one great encounter can still leave two people as acquaintances.

What Hall actually studied

The original article was first published online in 2018 and appeared in a 2019 issue of the Journal of Social and Personal Relationships. It drew on two samples. In one study, 355 adults who had recently relocated estimated time spent with a new acquaintance. In another, 112 first-year students reported time with two new acquaintances on three occasions over nine weeks. Across these settings, more shared time was associated with closer friendship categories or changes in closeness.

This is important because the study did not simply ask respondents whether friendship was valuable. It examined relationships at different stages and considered everyday talk and leisure activities. Yet the findings are not a universal countdown. People vary, a friendship label is subjective, and observational associations cannot establish that adding a fixed number of hours automatically creates closeness.

Why the way you spend time matters

Hall's findings suggest a distinction between simply being in the same place and spending meaningful time together. Shared leisure and everyday conversation were related to closeness. Two people could pass one another at work for months without learning much about each other, while a series of shared activities gives them more opportunities to notice humor, values and reliability.

It would be a mistake to turn this into a rule that every hour must be deep or emotional. Ordinary talk can be part of familiarity. A short walk, a funny story after class, or a discussion about a shared interest can create continuity without putting pressure on either person to reveal private information.

What the research cannot promise

The samples included recent movers and students, not a random global cross-section of adults. Hours in the first study were estimated retrospectively, which introduces recall uncertainty. The student study followed relationships for nine weeks, not across a lifetime. Those limits do not make the study useless; they mean we should resist presenting its estimated thresholds as a formula that applies equally to every city, culture, friendship style or life stage.

Most importantly, time does not replace mutual interest, respect or safety. Repeated exposure to someone who makes you uncomfortable is not a social goal. Friendship grows when both people want to be there.

How to use the finding without counting hours

• Choose a recurring activity that gives you a genuine reason to meet.
• Follow up after an enjoyable first conversation rather than waiting indefinitely.
• Mix shared tasks with ordinary informal conversation.
• Notice whether the other person also initiates and makes time.
• Let closeness develop at a pace both people find comfortable.

Instead of asking whether you have logged enough hours to call someone a friend, ask whether the next conversation is becoming easier, more personal and more reciprocal. That is closer to the human question the research is trying to illuminate.

Why hours are not a friendship scorecard

The study is often summarized by an eye-catching chart of approximate hours associated with changes in friendship status. That can be useful as an illustration of why time matters, but it is not a personal target. The participants had different life circumstances, the samples were not a random cross-section of all adults, and the meaning of "friend" or "close friend" depends on how individuals understand their relationships. Spending a particular number of hours in the same room does not require anybody to become a friend.

The nature of the time also deserves attention. Shared leisure can create a different interaction from sitting silently in a meeting at work. Conversation that moves beyond logistics may matter in ways a clock cannot record. Some relationships form through intense common experiences; others build gradually. An hours estimate cannot account for every cultural, personal or situational difference.

Read the method before sharing a viral statistic

One sample in Hall's study drew on adults who had recently relocated and asked them to reconstruct developing relationships; another followed first-year students over several weeks. Retrospective reports can be affected by memory and interpretation, while a student sample may have social opportunities that differ significantly from people with demanding jobs or caregiving responsibilities. The study tested associations, not a randomized program that assigned adults to make friends at exact time thresholds.

That matters when a platform, article or influencer turns the findings into a guaranteed recipe. It is more accurate to say that relationships generally need opportunities for interaction and that those opportunities can vary in quality. The number alone is not a causal instruction or a measured conversion rate from first meeting to friendship.

A better way to use the finding

Instead of counting hours with a new acquaintance, ask whether your life offers repeated chances to see the people you enjoy. A predictable walking group, a regular class or a monthly dinner can all create possibilities. Then notice more human signals: do you remember details, enjoy spending time together and both suggest another meeting?

The research gives a reason to value follow-through. It does not say to remain in a poor relationship until an invisible timer reaches the correct mark. Meaningful friendship still depends on mutual choice, respect and compatibility. Use time as something to make available, not something to accumulate as proof of progress.
