Free card centering tool
Measure your card's centering before you grade.
Compare your card's measured front and back centering against published PSA, BGS and SGC standards.
It's a centering assessment only — not an overall grade prediction, not authentication and not a guarantee of any grading outcome. Corners, edges and surface are up to you to inspect.

Example only · real cards, centering measured with our tool (front and back where shown). Corners, edges and surface not assessed.
Re-entering the TCG world alongside my kids highlighted a common hurdle: making sense of card centering and condition before sending cards off to be slabbed.
