Terms of Service

Last updated: July 15, 2026

Please read these Terms of Service ("Terms") carefully before using checkringsize.com (the "Service"), operated by Check Ring Size ("we", "us", or "our"). By accessing or using the Service, you agree to be bound by these Terms. If you do not agree with any part of these Terms, you must not use the Service.

1. Acceptance of Terms

By accessing, browsing, or using the Check Ring Size website and its tools, you acknowledge that you have read, understood, and agree to be legally bound by these Terms of Service and our Privacy Policy. These Terms apply to all visitors, users, and others who access or use the Service. If you are using the Service on behalf of an organization, you represent and warrant that you have the authority to bind that organization to these Terms.

2. Description of Service

Check Ring Size provides a free, browser-based ring sizing tool that allows users to estimate their ring size using screen calibration technology. The tool uses a physical reference object (such as a credit card or ID card) to calibrate your screen's pixel density, then measures your finger dimensions to calculate an approximate ring size in multiple international standards (US, UK, EU, JP, Indian).

The Service also provides educational content including ring size charts, measurement guides, conversion tables, and informational blog articles related to ring sizing and jewelry.

3. No Professional or Medical Advice

The ring sizing tool and all content provided on this website are for general informational and educational purposes only. The measurements and size estimations provided by our tool are approximations and should not be considered as a substitute for professional measurement by a qualified jeweler.

While we strive for accuracy through our credit card calibration system, numerous factors can affect measurement results, including but not limited to: variations in screen hardware and display technology, screen protectors or tempered glass overlays, device orientation and tilt, user finger placement accuracy, temperature-related finger swelling, and individual finger shape variations. Always consult a professional jeweler for an exact measurement before making expensive jewelry purchases.
