Formula Used
The calculator starts with the standard Pathfinder strength load table.
It finds the base light, medium, and heavy limits for the entered Strength score.
For Strength scores above 29, the table pattern is extended by multiplying capacity by 4 for every 10 extra Strength points.
The main formula is:
Adjusted capacity = base capacity × creature size multiplier × carry multiplier × custom multiplier.
Total carried weight is:
gear + armor + containers + miscellaneous + coin weight + itemized gear.
Coin weight uses:
coin weight = total coins ÷ coins per pound.
Lifting and dragging use physics style force approximations:
overhead lift = heavy load,
lift off ground = heavy load × lift factor,
and
push or drag = heavy load × drag factor.
The default lift factor is 2.
The default drag factor is 5.

Pathfinder Carry Weight and Physical Load
Why Carry Weight Matters
Carry weight shapes movement, tactics, and survival. A character can own great gear and still suffer when too much is packed. Armor, weapons, rope, food, coins, and treasure all add mass. The total can change a clean plan into a slow march. This calculator helps players see that limit before the party enters a dungeon.
The Physics Idea
The physics idea is simple. A creature has a force limit. Strength describes that limit in game terms. Size changes leverage. Body shape changes support. A quadruped spreads weight across more limbs. A larger creature also has more body volume. That is why multipliers are important. They turn a basic strength table into a better model.
Load Tiers
Light load is the safe zone. It keeps movement flexible. Medium load starts to slow a character. Heavy load creates stronger penalties. These tiers matter during chases, climbing, swimming, stealth, and long travel. A heavy pack may be fine in town. It can become dangerous on a cliff, bridge, or battlefield.
Coins and Item Details
Coins are easy to forget. They often become the hidden weight in a treasure haul. The calculator lets you set coins per pound, so table rules stay flexible. The itemized list also helps. You can enter several lines of gear and keep the math clear. That makes inventory review faster during play.
Lifting and Dragging
Carrying is not the same as lifting. Lifting off the ground can exceed normal carrying limits, but movement becomes limited. Dragging can be higher still, because friction and surface conditions change the effort. The calculator includes lift and drag factors, so you can judge doors, crates, bodies, statues, carts, and fallen allies with better consistency.
FAQs
1. What does this calculator measure?
It measures Pathfinder light, medium, and heavy load limits. It also estimates lift limits, drag limits, current speed, penalties, coin weight, and total inventory weight.
2. Can I use kilograms?
Yes. Select kilograms as the input unit. The calculator converts values internally and displays results in the selected unit.
3. How are coins counted?
Enter the total number of coins. The calculator divides that number by the coins-per-pound value. The default is 50 coins per pound.
4. Does size affect the result?
Yes. Fine, Tiny, Small, Large, Huge, and bigger creatures use different capacity multipliers. This reflects body mass and leverage differences.
5. Why choose biped or quadruped?
Quadrupeds usually carry more weight than bipeds. Four supporting limbs spread the load better. Select the body type that matches the creature.
6. What is the custom multiplier for?
Use it for magic items, house rules, special traits, spells, or campaign-specific adjustments. Keep it at 1 when no extra rule applies.
7. Why does speed change?
Medium and heavy loads can reduce movement. The calculator applies common reduced speed values and shows the current movement result.
8. Can I export the result?
Yes. Use the CSV button for spreadsheet data. Use the PDF button for a clean session note that can be saved or shared.
