Source hierarchy
For machine specifications we prefer manufacturers and authorized retailers. For affiliate terms we link to the merchant's own program page when available. Third-party articles are not treated as specification authority.
No hidden machine ranking
The calculators recommend equipment classes or modeled head counts, not “winner” products. Commercial relationships do not change capacity formulas.
AI disclosure
AI tools assisted with research synthesis, drafting, code generation and quality checks for this site. Calculations are rule-based JavaScript, not generative AI. Methodology and source links are published so assumptions can be inspected.
Corrections
If you find an outdated specification, broken source or reproducible calculator defect, email hello@stitchcapacity.com with the page, source and correction.
