FacebookHow much does a litre of epoxy resin weigh
Quick answer
The weight of one litre of epoxy resin typically ranges from 1.05 to 1.15 kilograms, depending on the specific formulation and density. This precise measurement is essential for calculating material requirements, cost estimations, and mixing ratios, especially in woodworking, deep pour, jewellery, and casting applications.
Accurately calculate epoxy resin weight for every project
Accurate measurements are vital when working with epoxy resin. Whether planning a river table, jewellery, art, or large casting project, knowing exactly how much a litre of epoxy resin weighs is crucial for perfect results and budgeting. This guide is for makers, professionals, and hobbyists looking to match resin quantities to project size, prevent wastage, and achieve precise mixing every time.
Understanding Epoxy Resin Weight by Volume
The density of most commercial epoxy resins falls between 1.05 and 1.15 kg per litre. This means that 1 litre of resin will usually weigh around 1.1kg. However, minor differences arise depending on resin type, additives, and manufacturer formulation. This information is indispensable for converting litres to kilograms for accurate measuring, especially when mixing by weight as many epoxy suppliers, including ResinPro, recommend. Deep pour epoxies may be slightly denser compared to jewellery or surface-coating variants, but all ResinPro epoxies will approximate this weight range, supporting reliable project planning and purchasing.
Measuring Epoxy Resin: Litres vs Kilograms
Epoxy resins are typically supplied by weight but often measured by volume. Most ResinPro formulas have a density of about 1.1kg per litre, so 1 litre generally equals 1.1kg. Accurately converting between litres and kilograms helps you measure, mix, and order exactly what you need for your project—eliminating excess and ensuring consistent results regardless of project scale.
“Trasparente” – Multipurpose Clear Epoxy Resin for Casting – Up to 2cm
This professional-grade clear epoxy resin is formulated for detailed castings, including art and small to medium table projects. With a density typical of premium epoxies (around 1.10kg/litre), it’s excellent for those wanting clarity and consistency in their work. Its self-levelling nature and high scratch resistance make it a favourite for both beginners and experts working on surfaces, decorative pieces, and restoration projects.
With easy mixing and integrated UV protection, “Trasparente” – Multipurpose Clear Epoxy Resin for Casting – Up to 2cm is ideal where precise volume-to-weight conversion is essential for success.
“Icrystal” – Clear Epoxy Resin – Odourless Formula – Up to 1.5cm
For surface coatings and creative projects like jewellery or table tops, “Icrystal” offers perfect transparency and an odourless working experience. Its density, still close to 1.1kg/litre, aids users switching between volume and weight measurements, particularly in small to mid-sized pours. The 2:1 mixing ratio ensures simplicity, and the product’s odourless feature makes it accessible for home and studio use alike.
Opt for the “Icrystal” – Clear Epoxy Resin – Odourless Formula – Up to 1.5cm for projects needing immaculate surfaces and reliable results.
“One-2-One” – Epoxy Resin for Handcraft, 1:1 Mixing Ratio
Designed for handcraft and jewellery, this medium viscosity resin stands out for its 1:1 mixing by volume – quick to measure and exceptionally user-friendly. Its weight per litre, around 1.10kg, is also straightforward for those making small castings or surface coatings where accurate batch sizes eliminate waste. The non-toxic formulation makes it suitable even for those crafting at home or in confined spaces.

How Resin Weight Affects Your Project Planning
Knowing the weight per litre of epoxy resin assists in batch calculations, optimising material orders, and correct mixing – especially when scaling up for large pieces. It prevents costly mistakes, ensures you purchase enough for your requirements, and matches the manufacturer’s recommended ratios for best curing results. Always check product-specific datasheets if available, and consider using a scale for accuracy rather than relying on visual volume alone.
Tips for Mixing and Weighing Resin
Use digital scales for the most accurate measurement—especially when working with weight-based mixing ratios. Always account for the combined density of resin and hardener to avoid errors. Refer to manufacturer guidance for each epoxy variant for the most precise conversion. For perfect results, measure twice before mixing.

Frequently Asked Questions
How do I convert litres to kilograms for epoxy resin?
Multiply the number of litres by the resin's density (usually about 1.1kg per litre) to get the weight in kilograms.
Does epoxy resin density vary between products?
Yes, minor variations exist, but most resins fall between 1.05 and 1.15kg per litre depending on formula and additives.
Why is it important to know the weight of epoxy resin per litre?
Knowing the weight ensures exact mixing ratios, prevents waste, and helps estimate how much resin is needed for a specific job.
How much does a deep pour epoxy resin weigh per litre?
Deep pour epoxy resins generally weigh about 1.1kg per litre, similar to surface and jewellery resins.
Should I measure epoxy resin by weight or volume?
Check the manufacturer’s recommendation, but weighing by scale is often more accurate, especially for large projects.
What's the best way to estimate how much resin I need?
Calculate your project’s volume and convert to weight using density. Always allow a small margin for overfill.
Why do suppliers sell epoxy resin by weight if it's measured by volume?
Epoxy and hardener densities differ, and weight-based sales allow for accurate formulation and transport.
