Formula breakdown
Formula
V = l × w × d × (1 + allowance) ; m = V × ρ= 600
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 not just fill the mould and see how much resin I used?+
Calculating volume in advance avoids mixing resin twice (which risks a visible layer line if the first pour cures before the second) and avoids wasting mixed resin, which cannot be put back once activated and starts curing immediately.
How do I calculate volume for an irregular-shaped mould?+
For irregular shapes, the most reliable method is to fill the mould with water first, measure that water volume, then convert it to resin volume, since calculating irregular geometry mathematically is error-prone; this calculator handles the standard geometric shapes directly.
Why does resin mixing ratio matter for the total volume, not just the final product?+
Most epoxy resins mix at a fixed ratio by volume or weight (like 1:1 or 2:1 resin to hardener), and getting the total volume right upfront lets you measure out the correct proportion of each component rather than guessing and risking an under-cured or tacky result.
Does resin volume equal the final cured volume?+
Nearly, but not exactly: most resins shrink very slightly during cure (typically under 2%), and some mixed resin is inevitably lost to the sides of the mixing cup, so it's standard practice to mix 5-10% more than the calculated mould volume.
How do I handle a mould with multiple cavities?+
Calculate the volume of a single cavity, then multiply by the number of cavities, rather than trying to estimate the whole mould's volume at once, since cavity shapes are often more complex than the mould's outer dimensions suggest.
