Aquarium volume, footprint & surface-area calculator

Calculate volume, footprint and surface area in metric or US customary units, then compare the geometry signals that matter to stocking plans.

Why the same volume can stock differently

Two aquariums can hold a similar amount of water while providing very different horizontal swimming distance, bottom territory and air-water surface. StockingLab therefore carries the dimensions into the full planning model.
