Below is a table that outlines how much a character can carry. Enter a strength score and click ENTER to calculate the carrying capacity. A small and medium creature can carry 15x their Strength score. A creature can drag, push and lift 2x that amount. For each size category above Medium, double the creature’s carrying capacity and the amount it can push, drag, or lift. For a Tiny creature, halve these weights.
Alternatively, you can find the carrying capacity for animals and carts/wagons.
If a creature carries weight in excess of 5 times their Strength score, they are encumbered, which means their speed drops by 10 feet. If they carry weight in excess of 10 times their Strength score, up to the maximum carrying capacity, they are instead heavily encumbered, which means their speed drops by 20 feet and they have disadvantage on ability checks, attack rolls, and saving throws that use Strength, Dexterity, or Constitution.
The table below uses the STR above.
