Load as a Game Physics Problem
Carry weight is more than a bookkeeping rule. It is a simple model of force, balance, and movement. A stronger creature can hold more mass. A larger body can spread that mass across more muscle and frame. The calculator turns those ideas into clear limits.
Why Size Matters
Size changes the working capacity. Tiny creatures carry half the usual load. Large creatures carry twice as much. Huge and Gargantuan creatures grow again by repeated doubling. This mirrors the way larger bodies can resist more load. It is not perfect physics. It is a practical tabletop shortcut.
Encumbrance and Motion
Weight affects motion before it reaches a hard limit. Variant encumbrance shows this well. A character can still move while burdened, but speed drops. Heavy loads also make physical reactions harder. This creates meaningful choices. Players must decide whether extra treasure is worth slower travel.
Armor, Coins, and Small Items
Small items add up quickly. Coins are a common example. A few coins mean little. Hundreds of coins become a real burden. Armor also changes the result fast. Heavy armor may be safe in battle, yet costly during travel. The calculator helps compare those tradeoffs before the next dungeon room.
Using Results at the Table
The result should guide play, not stop play. Dungeon Masters can adjust the custom multiplier for magic bags, mounts, house rules, or special ancestry features. Players can use the CSV and PDF downloads as inventory records. This keeps the session smooth and reduces repeated math.
Planning Better Adventures
Carry planning supports better pacing. A party that tracks weight knows when to sell loot, cache supplies, or hire transport. It also makes Strength valuable outside combat. The strongest hero may become the party hauler. That gives the character a useful role during exploration.
