5e Inventory sheet

So it looks like this:

The slot sizes

Forget about weights. Clear your mind. This system replaces that with item slots of four different sizes. Tiny, small, medium, and big.

Tiny for things you put in your pouch

Small for things you put in your bag

Medium for things you hang from your belt

Big for things you strap onto your bag

How to use this

List your strength, and ⅓ and ⅔ of it too. Check your encumbrance budget. One check mark tells you three things: your penalty (no penalty, just a little slower, or a lot slower and disadvantage on all strength, dex and con rolls), your current gear weight, and how many circles you can mark. Mark that many circles. You’ve already paid for them with the check mark, so just go ahead. The backpack costs a double circle, mark both. Armor can cost 0, 1, 2, 3 or 4 depending on type. You can turn two medium slots into one small slot + one big slot by filling in the symbol. Fill in your gear in the slots that you’ve gotten by marking circles.

That’s it!

In pouches & sacks: 50 tiny ↔ 1 small, 250 tiny ↔ 1 medium, 450 tiny ↔ 1 big. Outside of “pouch space” it’s one coin per slot. So… get pouches.

The rest should be self-evident so go play! Here is my list of item sizes and the most useful info; and here for an excessive amount of behind-the-scenes rambling & design intent.
