m = V × fill × n × ρ= 225
Note
Simplified model: these are standard craft estimates based on rectangular layouts, quoted gauge and nominal densities. Real fabric nap, directional prints, shrinkage, pattern matching, yarn lots and supplier SAP values vary, so always make a swatch or test piece and buy a little extra.

Why isn't wax quantity just the container's volume?+
Wax shrinks slightly as it cools and solidifies, so filling a container to its exact volume in liquid wax results in a slightly under-filled candle after curing; container volume needs a small adjustment factor to account for this shrinkage.
Does wax type change how much I need for the same container?+
Yes, different waxes have different densities, so the same volume of soy, paraffin, or coconut wax weighs a different amount; this calculator converts container volume to wax weight using the density of your selected wax type.
How much wax do fragrance oil and dye actually displace?+
Fragrance oil is typically added at 6-10% of wax weight and does add measurable volume, so for scented candles the wax quantity should be reduced slightly, or the container filled a bit less, to leave room for the added fragrance load.
Why does the calculator ask for container volume in fluid ounces or milliliters, not weight?+
You're filling a fixed physical space, so volume is the natural starting measurement; the calculator then converts that volume to a wax weight (in ounces or grams) using density, since wax is normally measured by weight when melting and pouring.
Should I account for the wick and any embeds separately?+
Yes, thick wicks and solid embeds (like dried flowers or crystals) displace some wax volume, so for candles with substantial embeds, reduce the calculated wax slightly or expect a small amount of leftover melted wax after pouring around them.
