Carrying capacity

All items in DDO have weight. The amount of weight a character can hold at maximum is represented by a bar at the bottom of the inventory screen labeled Load. As the bar slowly fills from Load: Light to Load: Medium, and Load: Heavy the character's speed and ability to perform certain actions is hindered. This hindrance, along with the limit to the unhindered load one is carrying, is often informally referred to as encumbrance.

The higher the strength, the more a character can carry. Note this is not based on the strength modifier, but the actual value, so increasing your strength to an odd number does increase your carrying capacity even though your strength modifier remains the same.

The amount a character can carry (weight wise) is governed not only by strength, but also by size. Halflings and Gnomes have 3/4 the maximum carrying capacity of other races with the same strength.

This lists the confirmed carrying capacities based on strength. It also has at what point you reach Medium Encumbrance and Heavy Encumbrance (aka Burdened)

• Load: Light (0% to 33.33% load)
  • You incur no penalties.
• Load: Medium (33.34% to 66.66% load)
  • Reduces run speed by 5%
  • Caps your maximum dexterity bonus at 3
  • Gives you a -3 armor check penalty
  • Monk characters become uncentered.
• Load: Heavy (66.67% to 100% load)
  • Reduces Run speed by 12%
  • Caps your maximum dexterity bonus at 1
  • Gives you a -6 armor check penalty
  • Prevents the use of Evasion
  • You are given the Heavy Encumbrance/Burdened status ("You're burdened.").
• Load: Other (more than 100% load)
  • Reduces Run speed by 31%
  • Caps your maximum dexterity bonus at 1
  • Gives you a -6 armor check penalty.
  • You are given the Overloaded status ("You're overloaded!").
