55/45 Centering

See exactly what 55/45 centering looks like on a trading card and what grade PSA, BGS, CGC, and SGC will give it. A faint imbalance is visible on close inspection — one border is roughly 22% wider than the other but the difference is subtle.

What 55/45 centering means

A 55/45 ratio means one border is 55% of the combined border width while the opposite border is 45%. In a 3.0mm total border, that splits as 1.65mm vs 1.35mm.

A faint imbalance is visible on close inspection — one border is roughly 22% wider than the other but the difference is subtle.

Real-world example: Modern Topps Chrome and Pokemon TCG cards in this range often qualify for PSA 10 but lose centering sub-grades on BGS.
