Fabric Yardage Calculator

📖 Overview

Calculate fabric needs for upholstery drapery or sewing projects using layout-aware inputs.

Pattern repeat handling rounds cuts so motifs align across panels.

Waste factor covers shrinkage mistakes and test cuts before final assembly.

Final output reports both metric and yard units for smoother ordering.

Use these default and higher-pressure example inputs to explore how sensitive this calculator is before using your real numbers.

This calculator applies a direct math model based on the inputs above.

💡This calculator is scenario-based. Better input quality leads to better decision quality.

Use this tool when you need a fast decision during active planning or execution.
Use this before committing money, time, or tradeoffs that are hard to reverse.
Use this to compare options using the same assumptions across scenarios.

Results can be misleading if key inputs are missing, stale, or unrealistic.
Very small or very large values may amplify rounding effects and interpretation risk.
If assumptions change mid-decision, recalculate before acting.

💡 Validate units before comparing scenarios.

💡 Run multiple values to understand sensitivity.

💡 Use outputs as estimates, not guarantees.

❓ Is this output exact?

It is a fast estimate based on provided inputs and model assumptions.

❓ Can I compare different scenarios?

Yes, this tool is designed for quick side-by-side checks.
