Belt Balancer Calculator

Split N belts onto M evenly fed belts, or collect M producers onto N belts, with splitter and merger counts, exact rates, the smallest belt tier per segment and a manifold alternative.

How to read the diagram

The building icon shows a splitter or merger; hover over it for the name. Small arrows show the belt direction, and the belt colour indicates its tier. Each building has three stacked ports per side, shown as short ticks, with a separate connection for each belt. At a simple crossing, the vertical belt curves over the other one. A real branch has no arc. Dashed orange lines are loopbacks; red belts are overloaded. The grid uses 1 m steps and 6 m foundation spacing.

Each input and output has a rate field in the diagram. Enter a value, or leave it on auto to split the flow evenly. Use the dashed "+" below each side to add a port, and the "×" on a port to remove it.

Zoom and fullscreen live in the toolbar above the diagram.

Hover over any belt to see its exact fraction of the total rate. The mechanics behind splitters, mergers and manifolds are explained in Belt balancers and Belts & pipes.
