Q&A - Size of coal bin | Hearth.com Forums Home

 · ard coal has little chance of igniting from any source of combustion nearby, so I would not worry about this. Coal takes up approx 40 cubic feet per ton, so a 4x4x4 would only hold about 1 1/2 tons. As far as construction, plywood or boards placed on upright 2x4 studs makes for a fine bin.
