Every item in Old School RuneScape has weight, which can affect a user in their gameplay. Players can see the total weight of the items they have equipped (measured in kilograms) or are carrying in their inventory on the Equipment Stats screen. Many items weigh with decimals, but the Equipment Stats screen will round down to the nearest kilogram. For example, a rune platebody weighs 9.979 kg, but will be displayed as 9 kg.

The rate at which energy depletes while running scales linearly between 0 kg and 64 kg weight, where having 0 kg weight will deplete a player's run energy at the normal rate and having 64 kg weight will deplete a player's run energy at exactly twice the normal rate. Having a weight outside the range of 0 kg to 64 kg has no additional effect.[1] A player's Agility level contributes to how quickly run energy is restored, but does not affect the rate at which a player's run energy is depleted.

Some activities in Old School RuneScape require players to not weigh more than a certain amount. Example: diving off Port Khazard during and after Recipe for Disaster (Freeing Pirate Pete subquest); walking on the bridge in Temple of Ikov.

Stackable items such as runes, coins, and other items do not have a weight. Some items also reduce weight instead of adding, which is very useful for quests or activities that require a lot of running.

Weight reducing items[edit | edit source]

Item Weight (kg)
Spotted cape.png Spotted cape -2.267
Spottier cape.png Spottier cape -4.535
Agility cape.png Agility cape -4.0
Boots of lightness.png Boots of lightness -4.535
Penance gloves.png Penance gloves -4.535
Graceful hood.png Graceful hood -3.0
Graceful top.png Graceful top -5.0
Graceful cape.png Graceful cape -4.0
Graceful legs.png Graceful legs -6.0
Graceful gloves.png Graceful gloves -3.0
Graceful boots.png Graceful boots -4.0
Pufferfish.png Pufferfish -0.5

Currently, wearing the combination of a spottier cape, boots of lightness, penance gloves, graceful hood, graceful top and graceful legs allows the player to have weight as low as -27.605 kg; With a full inventory of pufferfish this is lowered to -41.605 kg, this is the minimum amount of weight currently possible. All weight reducing items are wearables and have to be worn to 'activate' the weight reduction, with the exception of pufferfish.

Greatest weight[edit | edit source]

The current greatest weight possible a player can weigh at any given time is 1,024.525 kg. Items required to wear in order to reach this weight are:

Slot Item Weight (kg)
Headwear Gold helmet 31.751
Cape Diving apparatus 10
Neckwear Seal of passage 4.535
Ammunition God blessings 0.51
Weapon Barrelchest anchor/Dinh's bulwark 30[d 1]
Shield - 0
Body Granite body 22.679
Legs Granite legs 15.875
Hands Skeletal gloves/Spined gloves 3.175
Boots Guardian boots 7
Ring Granite ring (i)/Granite ring 3
Inventory 28× Barrel of coal tar (or any variation) 28×32 (896)
Total 1,024.525
  1. ^ The Barrelchest anchor and Dinh's bulwark are two-handed weapons, therefore the Shield slot will be empty. They can also be substituted with Crate with zanik. It weighs 2 kg more, making the absolute maximum possible weight 1,026.525, but is only available during Death to the Dorgeshuun.

Weighing[edit | edit source]

Since some items' weights which have fractions are rounded off in the Equipment Stats screen, it's hard to tell the real weight. However, there are some weights to help find out the precise weight of an item.

Item 1 Item 2 Weight (kg)
Bones.png Bones Bread.png Bread 0.500
Shrimps.png Shrimps Cake tin.png Cake tin 0.100
Tomato.png Tomato Burnt shrimp.png Burnt shrimp 0.080
Vial of water.png Vial of water(m) Egg.png Egg 0.020
Brass key.png Brass key Lockpick.png Lockpick(m) 0.010
Wool.png Wool Uncut sapphire.png Uncut sapphire 0.003
Mith grapple.png Mith grapple(m) Al kharid flyer.png Al kharid flyer 0.001

Trivia[edit | edit source]

  • In RuneScript, the game's compiler accepts other units of measuring weight, using pounds (lb), ounces (oz) and grams (g).[2] Many items are assigned weights in different units within RuneScript, but are automatically converted to kilograms in-game. For example, the gold helmet is assigned a weight of 70 lbs, but it is converted to 31.751 kg in-game.
    • In addition, stackable items also have assigned weights, but they are overridden by the game's code to be 0 kg. For example, coins have an assigned weight of 2 grams (0.002 kg).
