Cache Sizes

On Geocaching.com, cache containers are classified into four sizes:

Micro

35mm film canisters and smaller containers; extremely small micro-caches are sometimes called nano caches.

Small

Larger than a micro, but smaller than a regular; examples include sandwich-sized Tupperware and military-surplus decon containers.

Regular

A regular size cache in a 50mm ammo can.

Standard size ammo cans and Tupperware containers.

Large

5-gallon buckets and larger containers; examples include large ammo cans, trunks, and jeeps.
