ResinBatch helps resin makers plan mixed-mold batches, tabletop coatings and deep-pour cavity quantities in metric or US units. Its separate ratio calculator splits a known weight or volume using the corresponding product-specified ratio.

The four calculators run in your browser without an account. Keep a printable plan or CSV batch sheet and use the free measurement worksheets and pour logs. Saved mold-batch projects stay on your device.

Geometry estimates do not determine safe pour depth, batch size or cure behavior. Follow the instructions for your exact resin.
