How to Use the Sailrite® Foam Calculator

Item # X-HT-300572

Knowing how much foam you need for your cushion project is step one to a successful DIY. Luckily, we've made it easy for you. The Sailrite® Foam Nesting Calculator helps you determine how many sheets of foam you need to order for your cushions. We sell foam in various sheet sizes, so the Foam Calculator will help you map out how to cut the foam in order to maximize efficiency, reduce foam waste, and save you money. The Sailrite Foam Calculator is the only nesting foam calculator in the world — and it's a free resource available to everyone. Let's learn more about this incredibly useful tool and why you should use it for your cushion projects. At the end of this blog, watch the demo video to learn more about the calculator and how to use it.

Learn how to use our Foam Calculator.

When using the calculator, the first step is to select which type of foam you need for your project. You can choose from High or Medium Density Polyurethane Foam, Dry Fast Foam or Closed Cell Foam. If you're not sure which type of foam you need for your project, you can sort on the Sailrite website by the "Foam Use" facet and select from popular foam projects, including cockpit cushions, pontoon seats, automotive seating, home decor cushions, patio cushions and more. We also have a great blog "Which Foam Should I Use?" (#300059XHT) with a flowchart that helps you determine the right foam for your DIY.

Once you've selected your foam type, you'll be prompted to input your cushion dimensions. You can add as many cushions as you need. Drag the cushion shapes around the grid that represents the foam sheet, fitting and nesting them together. Even if you have an irregularly shaped cushion — such as a keystone v berth cushion in a boat cabin — as well as several rectangular cushions, the calculator lets you rotate, flip or slice a cushion in half to fit the pieces on the foam sheet grid as efficiently as possible. Once you have your cushion shapes placed as efficiently as possible, you'll know what size of foam sheet to order.
