How does a card centering tool work?
A card centering tool measures the distances between a card's edges and its printed borders to calculate centering percentages.
Card centering tools work by detecting the borders of a card and comparing the size of the margins on each side. Digital tools like Midpoint allow users to upload a card image, then automatically analyze the image to provide left-right and top-bottom centering ratios. This helps predict how a grading service might evaluate the card's centering.
