How often should you text your friends? What the research suggests

No study says how many texts a friendship needs, and the right rhythm varies from person to person. What research does show is that friendships fade without regular contact, that closer friendships take more time, and that a single good conversation measurably lifts your day. A practical starting point: your closest few friends about once a week, close friends every week or two, good friends monthly or so, and a wider circle a few times a year, with time together whenever you can manage it.

Below: what the research actually says, a starting rhythm by closeness, what makes a text count, signs your rhythm isn’t working, and how to keep it up without a spreadsheet.

What does the research say about how often to talk to friends?

The research doesn’t give you a number, but it agrees on the direction: friendships need ongoing contact, closer ones need more of it, and the quality of contact matters as much as how often.

• Friendships come in layers. Evolutionary psychologist Robin Dunbar’s work describes personal networks as layers of roughly 5, 15, 50 and 150 people, each about three times bigger than the one inside it. The layers reflect both how often you interact and how close you feel. More on this in our guide to Dunbar’s number and your friendship circles.
• Friendships decay without contact. In the same 2016 paper, Dunbar writes that friendships have a natural rate of decay when there’s no contact; social media and messaging may slow it, but occasional face-to-face time may still be needed.
• Family is more forgiving than friendship. An 18-month study by Sam Roberts and Robin Dunbar followed 25 young people in England as they finished school. Their friendships lost closeness while family ties didn’t, and putting more effort into a friendship slowed the decline (more talking helped most for women, more shared activities for men). It’s a small study, so treat it as a pointer rather than proof.
• Close friends take time. Jeffrey Hall at the University of Kansas estimated it takes around 50 hours together to become casual friends, about 90 to become friends, and more than 200 to become close friends.
• One good conversation a day helps. In a later study, Hall and colleagues assigned more than 900 participants to have one kind of quality conversation with a friend. Once a day was enough to improve well-being by that evening, more was better, and face-to-face contact was more closely tied to well-being than digital contact.
• Texting is a big part of everyday friendship. In a May 2021 survey of 2,019 US adults, 54% had texted a friend in the past 24 hours, compared with 30% who had talked to a friend on the phone. The same survey found 47% had lost touch with at least a few friends over the previous year.
• Reaching out is appreciated more than you think. Across a series of experiments, people underestimated how much others appreciate being reached out to, especially when the message came as a surprise.

A starting rhythm by closeness

Here’s a rhythm to start from, sized to Dunbar’s layers. The intervals are our suggestion, built from the research above, not figures from a study. Adjust them to the people involved.

Circle	About how many	Suggested contact	What counts	Time together
Inner circle (best friends, partner, closest family)	Up to 5	Weekly or more; many people talk most days	Anything: memes, check-ins, calls	As often as you both can
Close friends	Around 15	Every week or two	A real exchange, not just a reaction	Roughly monthly, if you live nearby
Good friends	Around 50	Every month or two	Catching up, news, a “saw this and thought of you”	A few times a year
Wider circle	Up to about 150	A few times a year	Birthdays, congratulations, a quick hello	Now and then

Two things to keep in mind. First, these are minimums for staying close, not targets to hit: if you naturally talk to someone more, great. Second, a friendship can sit in a different circle for each of you, so the person you message monthly might think of you as an inner-circle friend. When in doubt, ask.

What makes a text count?

A text that gets a real response does more than a meme that gets a thumbs-up. In Hall’s 2023 study, the seven kinds of quality conversation were catching up, meaningful talk, joking around, showing care, listening, valuing the other person’s opinions, and sincere compliments. All of them work over text:

• Catching up: “How did the first week at the new job go?”
• Meaningful talk: “I’ve been thinking about what you said about moving. Still on your mind?”
• Joking around: a callback to a shared joke.
• Showing care: “Big day tomorrow. Thinking of you.”
• Listening: a follow-up question about what they told you last time.
• Valuing their opinion: “You know wine better than me. What should I bring to dinner?”
• A sincere compliment: “Your talk was great. You explained it better than anyone.”

Signs your rhythm isn’t working

• It’s one-sided. You always start the conversation, or they always do.
• It’s only logistics. You talk to arrange things but never actually talk.
• You only hear from each other on birthdays. That’s wider-circle contact for someone you’d call a close friend. When the next birthday message arrives, our guide to replying to happy birthday messages has lines that turn a thank-you into a catch-up.
• You feel a twinge of guilt when their name comes up. That’s usually a sign it’s been too long.
• Replies have slowed on both sides. Drift is gradual, which is what makes it easy to miss.

Because drift is so gradual, it helps to have something watch for it. On a Mac, Tera Chat flags fading chats before they go cold, from conversations that are decaying to ones that have turned one-sided.

If you’ve let a friendship slide, a short, specific message is the way back in. Our scripts for when you forgot to text someone back cover reconnecting after months.

What if you and your friend text differently?

Some people text all day; others prefer a long call every few weeks. Neither is wrong, and a mismatch isn’t a sign of different levels of care. Say what works for you (“I’m terrible at texting but I love a long call”) and look for a rhythm in the middle. With long-distance friends, lean more on scheduled calls and voice notes, since you can’t rely on bumping into each other; our guide to long-distance friendship has habits that stick across time zones.

How to keep the rhythm without a spreadsheet

You don’t need a system for your inner circle; you’ll talk anyway. The people who drift are the close and good friends in the middle layers. A few ways to keep them close:

• Put three to five names on a recurring reminder. One name a day, one message each.
• Tie contact to a routine. A Sunday walk is a good time to call one friend.
• Use a weekly review. Ten minutes on Sunday: who haven’t you heard from?
• Let group chats help, but not replace one-to-one messages.

If you’d rather not track it by hand, a keep-in-touch app can do the remembering; we compare options in our guide to keep-in-touch reminder apps. On a Mac, Tera Chat works from the conversations you already have in iMessage, WhatsApp, Telegram, Instagram and Tinder. Circles & goals let you group the people who matter and set how often you want to stay in touch. Each contact gets a health score out of 100 that weighs how two-way the conversation is, how recently and how often you talked, and its tone over the last 30 days. Circles, fading-chat alerts and the health score work without any AI set up. If you do set up AI, a weekly digest arrives every Sunday morning naming who’s drifting and who to message. It’s a Mac-only app, so it suits people who do a lot of their messaging at a computer.

The short version

• There’s no magic number; aim for regular, two-way contact matched to closeness.
• Start with about weekly for your closest few, every week or two for close friends, monthly or so for good friends, and a few times a year for the wider circle.
• One real exchange beats ten reactions.
• Messages slow the drift, but time together still matters.
