How long a family dinner actually lasts, by the clock
By Hollis Treadway, Contributing editor, research review · · 3 min read
Twenty-three minutes. That is the median length of a weeknight family dinner in the one set of timed observations I have been able to find, a small study of forty households with school-age children, filmed in their own kitchens over a two-week period and published in a journal of family studies about a decade ago.
Asked beforehand, the same households estimated an hour.
The gap is not a lie. It is a definition problem. The families counted dinner from the moment somebody was called to the table to the moment the last person left the room, and that span was often close to an hour. The observers counted the time during which more than half the household was seated and eating. Those are different events.
What fills the other thirty-seven minutes
Calling people to the table, in the filmed households, took a median of six minutes from first call to last arrival. Getting food onto plates took four. The first departure, almost always a child, came about fourteen minutes after the last arrival. After that the meal thinned out in a way the camera recorded and the families did not.
The adults, in roughly a third of the households, stayed at the table after the children left, for anywhere from two to thirty minutes. That tail is what the hour-long estimate seems to be remembering.
The six minutes of calling is the figure I would have guessed wrong. I would have said two. The observers logged the first call as the moment a parent raised her voice toward another room and the last arrival as the moment the last chair was pulled in, and between those two events, in the median household, the parent called three more times, plated food that cooled, and in eleven of the forty houses sat down alone for at least a minute.
Why this is worth knowing
The practical point is modest. A great deal of advice about family dinner, and a great deal of guilt, assumes a unit of about an hour. Rules about phones, rules about staying until everyone is finished, expectations about conversation, are written for an hour. The seated meal is a third of that. A rule designed for sixty minutes applied to twenty-three will be experienced as strict, and the household will conclude that it is failing at dinner when it is in fact doing dinner at about the speed everyone else does.
Two limits on all of this. Forty households is a small sample, all from one metropolitan area, and the presence of a camera changes how people behave at a table, although the authors argue, reasonably, that it would be expected to lengthen meals rather than shorten them. I have not found a larger timed study. Survey estimates, of which there are many, are self-reported and run between thirty-five and fifty minutes, which tells you mostly what people think dinner should be.
If you want a number to plan around, twenty-three is the one with a clock behind it.
