Hoser Math
We built this tool to help you estimate how much of a specific line will fit in your tray. Select your hose and size, then provide your tray dimensions. Let us know the length of each individual line to ensure we provide totals based on that.

Individual Tray Dimensions
Estimated capacity
Lanes: —
Folds per lane: —
Limiting factor: —
Remember, this is just an estimate. We pride our lines on packability because we know #PacksPrettyPullsPretty. This tool is intended to support planning and comparison — not replace physical validation. These results represent a theoretical maximum capacity derived from hose construction dimensions and tray measurements provided. Calculations assume ideal flat packing with uniform bend stacking and no interference from couplings or hardware. Apparatus tolerances and cover clearance should be confirmed prior to final specification decisions.
