JellyCalc is a planning and design app for jelly-roll rug makers.

It combines accurate fabric calculations with JellyCalc Designer, an interactive visual designer, so you can plan and design your rug with confidence.

🧮 JellyCalc Calculator

Calculate fabric and strip consumption for your jelly-roll rug based on size and layout. Adjust dimensions and instantly see how your requirements change.
