Weight

Carrying Capacity
Carrying Capacity determines, obviously, how much you can carry on your person with or without additional carrying options such as backpacks.

The standard space without a backpack for any survivor is 4 spaces, which can be explained by simply having pockets. Backpacks and other means to carry objects allow additional carry space. Going from a basic backpack granting 16 additional spaces (for a total of 20 spaces) and increases incrementally depending on the size and quality of the pack.

Weight and Space of Objects
An object's weight and space is determined by multiple factors, the first of which is common sense. For example, a 44 gallon drum full of oil isn't going to fit into a backpack. The second factor is the ZM's discretion (also paired with common sense), so if a ZM tells you that your Medkit weighs 1, it is ultimately his/her decision to determine the weight of an object, within reason. The final factor is quantity of the item. The ZM may tell you that a nail is worth 0 carry space, because realistically, if you were to put a nail on it's own into a backpack, you wouldn't even be able to notice it. Whereas if you were to take 100 nails, the ZM may say that they have a certain weight to them now that you are carrying bulk. Again, this is up to the ZM's discretion.

Examples
 * A bottle full of water would take up 1 space.
 * A machete would take up roughly 5 spaces.
 * A sleeping bag would take up 10 or so spaces.
 * etc

Encumbrance
If a player exceeds their carrying capacity, it will confer some negative effects on the player's character. One of these effects is losing the ability to sprint completely. Another is a -4 modifier to the Agility Statistic. It will also hinder a player's ability to move, lowering their movement depending on how much they are over encumbered by.
 * 0-5 over limit = -1m Speed
 * 6-10 over limit = -2m Speed
 * And so on...
