Card Centering Calculator
Upload a card photo cropped to its edges, then drag the four guides to the inner frame. You get the left/right and top/bottom centering ratios and an estimated centering grade. Centering is one of four grading factors, so this is a centering estimate, not an official grade.
Crop the photo to the card's outer edges first, then drag the red guides onto the inner frame border.
