What changes when…
Baseline comparison
Save a baseline, then change your inputs. The difference is current minus baseline. Saved values stay in this browser.
| Result | Baseline | Current | Difference |

Use the result
Check the closure and piping plan before cutting. Mark top and bottom orientation for directional fabric.
Assumptions that matter
- This is a cut list, not a fabric nesting or yardage guarantee.
- Zippers, piping, pattern matching and fabric stretch need separate treatment.
- The finished dimensions are chosen by you; foam compression is not modeled.
- A continuous band generally needs joins and a closure design.
Common questions
How is the result calculated?
The formula reference shows every equation and defines the input variables. Whole-item results explicitly round to whole quantities where needed.
How should I use the example?
The initial numbers are a worked example. Replace them with measurements from your own project before making a plan. Three calculated scenarios appear on the examples page.
Can I compare two plans?
Yes. Save a baseline, change one or more inputs, and compare the result table. The chart changes only one input at a time.
Does this upload my measurements?
No. Calculations run in this browser. Saving a baseline uses local browser storage; the scenario-link button includes entered numbers in a URL fragment you choose to share.
