Empty = 0. Otherwise: 1 + floor(14 × average slot fullness). Mixed-size groups assume items within each group can stack together; items with different types or components may need more slots.
Item thresholds
Minimum count for each signal using only 64-stack items in 5 slots.

About Minecraft Comparator Signal Calculator
Calculate Minecraft comparator signals from container fullness or redstone inputs. Find exact item thresholds and test compare and subtract modes.
Frequently asked questions
- How is container signal strength calculated?
- An empty container outputs zero. Otherwise, Java uses one plus the floor of fourteen times average slot fullness. Items count relative to their maximum stack size, so unstackable items fill a slot with one item.
