THE NUMBERS, EXPLAINED
How to use this calculator.
Single linear rail or combined uninterrupted equivalent, identical garment widths, gap only between adjacent garments. Separate rails must be evaluated separately.
Start with your inputs
Enter usable rail length (cm), garment width (cm), gap between garments (cm), garments to dry. Keep amounts in the units shown on each field. The example is a starting point, not a recommended value.
| Input | Example value |
|---|---|
| Usable rail length (cm) | 300 |
| Garment width (cm) | 40 |
| Gap between garments (cm) | 10 |
| Garments to dry | 8 |
A worked example
With the example inputs above, garment capacity is 6. Change the inputs to explore your own scenario.
| Result | Example answer |
|---|---|
| Garment capacity | 6 |
| Overflow garments | 2 |
| Rail used by fitted load (cm) | 290 |
How this is calculated
Garment capacity
Fit repeated garment widths plus gaps, allowing no gap after the last garment.
Overflow garments
Subtract rail capacity from garment count, floored at zero.
Rail used by fitted load (cm)
Multiply fitted garments by width plus gap and remove the final gap.
Symbols and units
- a
- Usable rail length (cm)
- b
- Garment width (cm)
- c
- Gap between garments (cm)
- d
- Garments to dry
Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.
Assumptions and limits
Single linear rail or combined uninterrupted equivalent, identical garment widths, gap only between adjacent garments. Separate rails must be evaluated separately.
Calculations use the values you enter. Blank or invalid inputs show an error instead of silently substituting zero. Results are displayed to useful precision; calculations retain the underlying numeric precision.
Questions about this tool
What does the result tell me?
Garment capacity; Overflow garments; Rail used by fitted load (cm). The result applies to the method and inputs described above. Check the units and assumptions before using it in a decision.
Why might another calculator differ?
Differences in units, rounding, timing or model definitions can produce different answers. Compare the input definitions and the method, rather than only the final number. For this tool: Single linear rail or combined uninterrupted equivalent, identical garment widths, gap only between adjacent garments. Separate rails must be evaluated separately.
Are my inputs stored or sent to AI?
Calculations on this page happen in your browser. The separate AI question finder sends its submitted conversation to OpenAI; these calculator fields are not sent. Favourites and recent tool names are stored locally. A shared link contains the inputs you choose to include.
