Density factors on their own tell you nothing. Pick the container you actually pour into and see what each wax works out to — weight, fragrance, burn time and cost.
One price is applied to every wax on purpose, so the cost row shows how much wax each one uses rather than what your supplier charges for it.
The container default. Forgiving to pour, frosts a little, holds up to about 10%.
The strongest hot throw and a glass-smooth finish. No frosting.
Hard enough to stand alone in a mould. Carries added fragrance poorly.
Across the 3 waxes you have selected, the amount you need varies by only 9 g — about 5% — while what they can hold varies by 6 percentage points of fragrance and the temperature they want to be poured at spans 17 °C. Density is not the decision. Fragrance capacity, finish, cost and the process each one needs are.
Burn time assumes one wick at 6 g/hr for 64–76 mm (2.5–3 in), held constant across every wax because the wick drives burn rate far more than the wax does.

Candle Making Quick Reference
Every column is the same arithmetic run with a different wax constant. Wax weight is the vessel volume times the fill level times that wax's density factor. Fragrance is that wax's own typical load applied to the result, because a single percentage across all of them would misrepresent every one. Burn time divides the wax weight by a consumption rate taken from the container's diameter — held constant across the columns on purpose, since the wick drives burn rate far more than the wax does. What the table tends to show is that the waxes differ much less in quantity than the marketing suggests, and that the real differences are in throw, finish and cost.
