Use this when you need to quantify a care-related measurement or cost before deciding what to do with a specific garment.
What this tool is actually telling you
Care calculations are descriptive. ISO 3758:2023 and GINETEX care information concern permitted textile-care treatments; the calculator does not override a product-specific instruction.
The result depends on the assumptions you enter. Treat it as decision support rather than a universal rule.
Inputs that make the answer stronger
- Use the same garment dimension before and after when calculating change.
- For temperatures or care actions, check the garment label before acting.
Worked example
If a garment length changes from 70 cm to 67.2 cm, the decrease is 2.8 cm, or 4% of the original length. That does not mean every dimension shrank by 4%.
How to use the result for a real decision
Use the number to understand the change, then follow the garment’s care label and material/construction context before attempting further treatment.
Why the answer changes when your assumptions change
Wardrobe economics depend on future behavior: how often you wear the item, how long you keep it, care costs and whether it competes with similar pieces.
Sources and verification
Wardrobe economics use transparent arithmetic from the assumptions you enter; there is no external universal target for an ideal wardrobe.
Questions people ask
Can shrinkage differ by direction?
Yes. Length and width can change by different amounts, so measure each important dimension separately.
Does a temperature conversion change the care instruction?
No. It only expresses the same temperature in another unit.
