Example Data Table
| Scenario | Workload | Fabric | Wrinkles | Power | Details | Estimated Total |
|---|---|---|---|---|---|---|
| Garden shirts refresh | 6 items × 0.5 m² | Cotton | Medium | 1600 W | 6 | ~34 min |
| Heavy work apron + canvas cover | 2.6 m² total | Canvas | Heavy | 2200 W | 10 | ~49 min |
| Poly blend quick pass | 4 items × 0.45 m² | Polyester | Light | 1400 W | 4 | ~18 min |

Formula Used
The calculator estimates ironing time from an effective ironing rate (minutes per area). First, total fabric area is calculated from item count or a direct area entry.
| Total area | Area = pieces × avg_area (items) or Area = input_area (area) |
| Effective minutes per m² |
min_per_m² = base × wrinkle × detail × quality × rework ÷ (power × steam × skill × batch)
|
| Work time | work_minutes = Area × min_per_m² |
| Break time | break_minutes = floor(work_minutes / 20) × 2 (Auto), or Manual value |
| Total time | total_minutes = setup + work_minutes + break_minutes + cooldown |
Factors are tuned for planning, not lab measurement. Use them to compare scenarios and pick settings.
How to Use This Calculator
- Pick a workload method. Choose “By items” for garments, or “By fabric area” for covers and sheets.
- Enter your workload. Add item count and average area, or enter total area directly.
- Set fabric and wrinkles. These drive the base time and wrinkle multiplier.
- Adjust equipment and technique. Power, steam, skill, and batching reduce time.
- Add setup, breaks, and cleanup. This makes the estimate closer to real sessions.
- Calculate and export. Use the buttons to download your latest result as CSV or PDF.
