A creature's default carrying capacity is 6 + Twice their Strength modifier. This is multiplied by their size, and other factors (such as magic items) are added after.
Example: A creature with +3 Strength has 12 CC.
Every item is calculated in Bulk.
A creature's carrying capacity handles how much Bulk they can carry all at once. Certain items, like
Muleback Chords can add onto your carrying capacity, or will have Bulk capacities of their own, like the time honored
Bags of Holding. Some abilities will increase or decrease bulk, making it harder for said creature to move after the fact.

Carrying Capacity Rules |
A creature's base Capacity is calculated in Bulk, with this representing 20-30% of that creature's body weight plus any strength enhancement they've done, as is the norm for an avcerage creature. To this end, a creature's Strength modifier increases their carry capacity by 2 for each +1 they have. In addition to this, a creature's size plays a part; where every size category beyond that is 1 step below (Small > Tiny > etc ) or above (Large > Huge > Gargantuan, etc) is divided or multiplied exponentianlly (respectively) by 2.
A creature's default Carrying Capacity is 6 + (That creature's strength modifier (including negatives) x 2) + other modifiers, which is then multiplied or divided by the creature's size modifier. Or:
(6+(2*STR)(Size)+OM) (Size T=0.25, S=0.5, M=1, L=2, H=4, G=8)
As an example, A medium creature with +2 STR would have a base carrying capacity of 10, a Tiny creature with a STR of +4 has 3.5 CC, and Huge creature with +1 STR has 16 CC.
For every 1 Bulk over their limit (rounded up), a creature slows down, losing -5 Movement. Carrying a Heavy Load over the course of a few hours / a short rest gives 1 level of Exhaustion.
