Terms of Service

1. Acceptance of Terms

By accessing or using the Kids Shoe Size Calculator ("the Service"), you acknowledge and agree to comply with and be bound by these Terms of Service. If you do not agree to these terms, please discontinue use of the website immediately.

2. Footwear Sizing Disclaimer & Not Medical Advice

Our sizing calculators, developmental age tables, and unit conversion charts are mathematical approximations derived from published footwear manufacturing guidelines (including ISO/TS 19407 and ASTM F2051). Because children's foot anatomy, width, arch height, and individual brand lasts differ significantly:

• Calculated sizes are recommendations, not universal guarantees of perfect shoe fit.
• We strongly recommend measuring your child's physical foot length with a ruler before purchasing footwear.
• Information on this website does not constitute medical, pediatric, or orthotic diagnosis. If your child experiences persistent foot pain, gait anomalies, or blistering, consult a licensed pediatric podiatrist.

3. Intellectual Property Rights

All proprietary algorithms, UI designs, graphics, branding, text copy, and curated conversion tables on this site are protected by copyright and intellectual property laws. You may not scrape, republish, or redistribute our datasets in bulk without prior written permission.

4. Affiliate Links & Commercial Partnerships

This website contains contextual referral links to authorized footwear retailers (such as Amazon and Zappos). Please review our Affiliate Disclosure for full details on how we earn compensation to keep this tool 100% free for families.

5. Limitation of Liability

Under no circumstances shall Kids Shoe Size Calculator, its creators, or contributors be held liable for any direct, indirect, incidental, or consequential damages resulting from sizing discrepancies, shoe return shipping fees, or reliance on information presented on this website.

6. Governing Law & Contact

These Terms are governed by applicable local laws without regard to conflict of law principles. If you have any legal questions regarding our terms, please contact us via our contact page.
