About Is My Card Centered?

Is My Card Centered? is a set of free browser-based tools for trading card collectors. The goal is to make common photo-based checks and research workflows faster, easier, and more consistent across the main site and related subdomains.

Current Tools

Card Centering Calculator helps estimate centering from a card photo using guide placement, perspective correction, and exportable results.

Card Defect Pre-Screener helps pre-screen a card photo with quick inspection views designed to make possible scratches and other issues easier to review.

Gem Finder helps explore PSA population data and identify gem-rate outliers with more context before overreacting to a single percentage.

What These Tools Are Not

These tools are not official grading services, not authentication tools, and not guarantees of grading outcomes. They are designed to support collector judgment, not replace it.
