FEMA asks households to have food, water and supplies for several days, with 1 gallon of water per person per day. Its Ready.gov kit page lists 14 basic items and 16 extras. Here they are, with what each is for and where the printable checklist says it differently.
Ready.gov, FEMA's preparedness site, sets no fixed number of days: "Being prepared means having your own food, water and other supplies to last for several days." After an emergency, it says, you may need to survive on your own for that long.
Read on 11 November 2026 at ready.gov/kit, last updated 1 July 2026, and in the printable Emergency Supply List. The printable list calls itself "only a starting point" for each family's own needs.
This page sticks to what FEMA itself lists. For a three-day kit counted per person, see our 72-hour kit list.

FEMA's gallon a day, over the CDC's 3-day minimum and its 2-week supply.
| People | 3 days | 2 weeks |
|---|---|---|
| 1 | 3 gal (about 11 L) | 14 gal (about 53 L) |
| 2 | 6 gal (about 23 L) | 28 gal (about 106 L) |
| 3 | 9 gal (about 34 L) | 42 gal (about 159 L) |
| 4 | 12 gal (about 45 L) | 56 gal (about 212 L) |
| 5 | 15 gal (about 57 L) | 70 gal (about 265 L) |
| 6 | 18 gal (about 68 L) | 84 gal (about 318 L) |
1 gallon is about 3.8 litres. Ready.gov adds that children, nursing mothers and sick people may need more, and that water needs can double in very hot weather. The water calculator does the sum for your home.
Ready.gov adds these according to your household's needs:
The printable checklist is older than the page, and a few lines read differently.

You don't know where you'll be when it happens, so FEMA plans for three.

A set place that everyone in the household knows, ready to take if you have to leave quickly.

Enough to shelter there for at least 24 hours: food, water, medicines and comfortable walking shoes in a grab-and-go case.

A kit of emergency supplies in case you are stranded.

"Several days." Ready.gov gives no fixed number. The CDC sets the water minimum at 3 days and asks for a 2-week supply where you can store it.
FEMA's list is for several days. Three days is the common floor, and our 72-hour kit list counts a kit for that long, person by person.
1 gallon (about 3.8 litres) per person per day, for drinking and sanitation. A family of four needs 12 gallons for three days.
On ready.gov/kit, under Emergency Supply List. Ready.gov also has it in other languages.
9-1-1. Ready.gov tells you to call it, or the fire department, if you have to get out of a burning home.


The 72-hour checklist turns a list like FEMA's into boxes you tick at home. The Fallback72 book covers water, heat, light, food that keeps and first aid on paper that works with the power out: join the list to hear the launch date first.
