Packing List Quantity Calculator
Gives a starting number for each kind of clothing, so you pack for the laundry rather than for the whole trip.

The formula
days to cover = days away, or days between laundry if shorter underwear and socks = days to cover + spares tops = days to cover bottoms = days to cover ÷ 3, rounded up
Bottoms get about three wears each and sleepwear about a week.
What to watch out for
Clothing that dries overnight can stretch this further. Lay it all out, then remove anything that is only there just in case.
Frequently Asked Questions
How many clothes do I need for two weeks?
With laundry every 7 days and one spare set, about 30 items in mixed weather: the same as a one-week trip.
How do I pack for a long trip?
Pack for the gap between washes, not for the length of the trip. After about a week, more days add almost nothing.
