About Earthquake Kit Checklist Size Calculator

Item count is per-person items times the household plus twelve shared items, with water, food and item weights combined to size the container. Volume rather than item count usually decides where a kit lives, and a five day kit for three people needs a large plastic tub rather than a rucksack.

Formulas

Item count

items = people x items per person + shared items
