The Sailrite Cushion Calculator is a tool designed to simplify the process of calculating the amount of fabric needed for making cushions. Whether you’re a seasoned upholsterer or a DIY enthusiast, this calculator takes the guesswork out of measurements, ensuring that you have enough material without wastage. It considers the dimensions of your cushion, the seam allowance, and the stretch of your fabric, providing an accurate estimate of the fabric required for your project.
Formula of Sailrite Cushion Calculator
To understand the calculations behind the Sailrite Cushion Calculator, it’s essential to grasp the basic formulas it uses:
Adjusted Length = Length + (2 * Seam Allowance)
Adjusted Width = Width + (2 * Seam Allowance)
Fabric Length = Adjusted Length * (1 + Fabric Stretch)
Fabric Width = Adjusted Width * (1 + Fabric Stretch)
These formulas adjust the length and width of your cushion to include the seam allowance, ensuring that the final product fits perfectly. The fabric stretch percentage is also accounted for, which is critical for materials that might expand or contract during use.
General Terms and Conversions Table
To further assist users, here’s a table of general terms and necessary conversions that might come in handy while using the calculator or working on upholstery projects:
| Term | Definition |
|---|---|
| Length | The longest side of the cushion |
| Width | The shorter side of the cushion, perpendicular to the length |
| Seam Allowance | The extra fabric around the edges, allowing for seams |
| Fabric Stretch | Percentage the fabric can stretch beyond its initial dimensions |
This table serves as a quick reference to understand the basic parameters required by the calculator, making it even more user-friendly.
Example of Sailrite Cushion Calculator
Consider making a cushion with the following dimensions: 18 inches in length, 18 inches in width, with a seam allowance of 0.5 inches and a fabric stretch of 5%. Using the formulas provided, the adjusted measurements and fabric requirements would be calculated as follows. Ensuring that you cut the right amount of fabric for your project.
Most Common FAQs
The standard seam allowance for cushions is about 0.5 inches. But it can vary based on your project requirements or the thickness of the fabric.
Yes, the Sailrite Cushion Calculator is versatile and can be use for a wide range of fabrics. Just ensure to input the correct fabric stretch percentage for accurate results.
If your fabric has no stretch, you can input 0% for the fabric stretch variable. This will adjust the calculations accordingly.
