Understanding Centering
Centering is one of several key factors in card grading — alongside corners, edges, and surface condition. It measures how evenly the card's printed design is positioned within the card's borders. While a great centering score alone won't guarantee a top grade, a poor one can hold your card back.
A perfectly centered card has equal borders on all sides — expressed as 50/50. Centering is measured in two directions:
- Left/Right (L/R): Horizontal centering of the design
- Top/Bottom (T/B): Vertical centering of the design
The ratio is always expressed as the smaller border / larger border. For example, 60/40 means the smaller border is 60% of the larger border's width — which is actually written as the percentage split between both sides.
L/R and T/B borders should be equal for a perfect 50/50
