How long should I wait before I worry about a reply?

For someone you just met or matched with, a few hours of silence means almost nothing, and a full day usually doesn’t mean much either. Start paying closer attention only when the gap is far longer than their own normal pace, and even then, the next move is one easy follow-up, not a night of worry.

So how long is too long?

There’s no universal number, but there is a useful rule of thumb: compare the silence to how this person usually replies.

Say Jalen, 24, met Ana at a friend’s rooftop party on Saturday. They talked for an hour, swapped numbers, and on Sunday afternoon he texted, “Really fun meeting you. Want to grab a drink this week?” It’s now Monday at lunch. Nothing.

Here’s what’s going on in Jalen’s head, separated out:

• What happened: one text, about 20 hours without a reply, starting on a Sunday.
• The reading: she wasn’t that into it.
• The fear: he misread the whole night and looks foolish.
• The next step: still open.

He doesn’t know Ana’s pace yet, because there’s only one data point. That’s the honest situation with most new people.

Researchers who study response times have found that pace is surprisingly regular for each person. In a 2006 analysis of more than 150,000 replies across email, class discussion boards and an online question service, Yoram Kalman and colleagues found that at least 70% of responses came within the responder’s own average time, and no more than 4% came after more than ten times that average.1 A separate 2006 study of more than 90,000 instant messages from 16 people found reply timing regular enough that computer models could predict, with up to 90.1% accuracy, whether a new conversation would get an answer within a few minutes.5 Those weren’t dating texts, so treat both as a rough guide. But the logic carries over: if someone usually answers within an hour, a reply ten-plus hours later is out of character. If they usually take half a day, a day is just them.

Doesn’t everyone our age reply instantly?

It can feel like it. Back in 2011, Pew Research Center found that texters aged 18 to 24 sent or received an average of 109.5 texts a day.2 But the median texter of any age handled just 10 a day,2 which tells you averages are pulled up by heavy texters.

That data is old, and messaging has changed a lot since. The point still holds: the person you’re waiting on might be a constant texter, or they might be someone who checks their phone in a few batches a day. Your own pace isn’t the measuring stick.

What if it’s a new match on the apps?

Then silence is even less personal. In a large 2018 study of a free dating service in four U.S. cities, Elizabeth Bruch and M. E. J. Newman of the University of Michigan found that both men and women tended to message people rated about 25% more desirable than themselves, and that the chance of getting any reply dropped steeply as that gap grew.3

In plain terms: on the apps, lots of first messages never get any reply at all. It’s how the setting works. A quiet match from Tuesday isn’t a review of you.

What if they’ve actually ghosted me?

It happens, and it’s worth naming without making it bigger than it is. In a 2020 survey of 626 adults aged 18 to 40, run by researchers in Spain, about two in ten said someone they considered a dating partner had ghosted them in the past year.4 Slightly more than three in ten had experienced or initiated breadcrumbing, the on-and-off attention that never turns into plans.

Here’s the interesting part. Breadcrumbing was linked to lower life satisfaction and more helplessness and loneliness. Ghosting on its own wasn’t.4 That’s one survey, and it can’t say why. But it fits a common experience: the clean silence stings, while the half-signals keep you waiting.

What to do tonight, and this week

• Name the window before you start waiting. For a first text to someone new, give it a full day. For a match you’ve barely talked to, a couple of days.
• Use their pace, not yours. If you’ve texted for a week, notice their normal rhythm. Only a big jump away from it is worth a second look.
• Send one follow-up, and make it easy. A specific plan (“Thursday at 7, that bar near the park?”) is easier to answer than “hey?”
• Don’t send a test. Waiting longer to reply to them, or posting to see if they look, just adds more noise.
• Set a checking limit. Turn off notifications from that thread for the evening, or check once before bed and stop.
• Decide your cutoff in advance. One follow-up with no answer is an answer. You can let it go without a verdict on yourself.

If waiting on replies regularly takes over your days, keeps you from sleeping, or you find the worry is hard to control across lots of parts of life, not just dating, that’s worth bringing to a licensed mental-health professional. Constant worry that’s hard to switch off can be part of an anxiety disorder,6 and only a qualified professional can say whether it is.

What doesn’t the research show?

• No study can tell you what one person’s silence means. These are patterns across many people.
• The response-time research used email, online forums and instant messaging, not dating texts.15 It’s a useful guide to rhythm, not a dating rule.
• The Pew texting figures are from 2011,2 before most current messaging apps took over.
• The dating-app study covered heterosexual users in four cities on one service.3
• The ghosting survey was a preliminary study from Spain, based on self-reports.4
• Sometimes silence really is a no. The goal isn’t to explain it away. It’s to stop treating hour three like it’s day three.
