Pounds per person per day (PPPPD) is an acronym used when determining how much food to pack on multi-day backpacking trips. By utilizing a digital scale and packing calorie-dense foods, after a little practice one can simply multiply their personal PPPPD by the number of days a trip will last, while also of course ensuring that requirements for each meal of the day are met. Usually after assembling food for a trip and weighing the lot, the PPPPD number helps save weight in your pack by making sure you’re not overpacking food (though a little extra is of course a great idea).

Backpacking Jargon - Food PPPPD

The Ursack food bag is one way to pack your backpacking food (alternatively you could use a PCT style / method food bag hang.

Generally, starting with 2lbs of food PPPPD is a good starting point, going up or down a bit from there after testing on a trip or two and taking extra until you have your own calculation all worked out. Thus, if you’ve determined that 2 PPPPD is a good number without too much food left over after a trip, but with enough of a buffer and without going hungry, and you’re now packing for a 7 day trip, your food bag with 14lbs of food will be just about right. As previously mentioned, I like to utilize a digital scale to weigh out my backpacking food and in particular, the Feedback Sports Alpine hanging scale (use with food in grocery bags) works very well.
