What is a card centering tool?
A card centering tool is a device or app used to measure how evenly a trading card's borders are aligned to estimate its visual centering.
A card centering tool helps collectors and sellers measure the border alignment on trading cards to assess how centered the card design is. Proper centering is important for card grading, as grading services like PSA and BGS evaluate centering as part of a card's overall grade. Tools can be physical templates, rulers, or digital apps like Midpoint, which analyze images to provide centering measurements and ratios.
