Estimate how many hours packing a home takes by room.
Packing time is best estimated per box rather than per room, because a box is the unit of work regardless of what goes in it. Twelve minutes is a fair average: books and linen go in at five, a kitchen cupboard with wrapping takes twenty or more. Multiply by the box count, add about 25 minutes per room for taking beds and shelving apart, and you have the total person-hours. Dividing by the number of packers gives elapsed time, but note that it divides less cleanly than it looks — two people in one room get in each other's way, so parallelism works best when each person owns a room. Six hours is a realistic packing day; nobody wraps glassware carefully for ten hours straight.
Packing Time
Boxes = rooms x boxes per room; person-hours = (boxes x minutes per box + rooms x 25) / 60; elapsed hours = person-hours / packers
Roughly 20-25 person-hours of boxing plus disassembly, so two people working two full days. Kitchens and garages consistently take twice as long as people expect.
Two to three weeks out, one room per evening, beginning with what you do not use daily — books, out-of-season clothes, garage. Leaving it to the final weekend is the main cause of unlabelled boxes.
