I've made another reference sheet for AD&D, this time it's a chart of the encumbrance values for all items in the game, along with armor bulk and encumbrance levels. You can find it here.
Not much to say about this one. I've just put together information on encumbrance that is normally spread at different places over the DMG and PHB. Note however that the rule for carrying capacity for containers is my interpretation.
I say that a container holds twenty times its own encumbrance value. I've made that rule to fit the example given in the DMG Appendix O, and also the values given by some of the old AD&D character sheets.
The latter put the capacity of a backpack at 300, but I believe the example in Appendix O sums up to 325. So I've decided on a capacity of 400 for the backpack, which, as in OD&D, is the same as that of a large sack.
