Understanding 55/45 Centering: Meaning, Grading, and Value

A 55/45 centering ratio means the borders on one side of your card are 55% and 45% on the opposite side - slightly off-center but within top grading standards for most companies.

What Does 55/45 Centering Mean?

Centering describes how evenly the printed image sits within the borders of a trading card. A 55/45 centering ratio means one border is roughly 55% the width and the opposite border is about 45%. This slight off-centering is typically only noticeable under close inspection and is considered excellent for most grading standards.

Is 55/45 Centering Good?

Yes, 55/45 is considered a strong centering ratio. For most grading companies, this falls within the tolerance for gem mint grades on the front of the card. Specifically, PSA allows up to 55/45 centering on the front for a PSA 10 (GEM-MT) grade. Other grading companies have similar or slightly different standards, so always check their current published guidelines.

What Grades Does 55/45 Centering Allow?

For PSA, 55/45 centering on the front can qualify for a PSA 10, their highest standard, assuming corners, edges, and surface are also gem mint.
Other graders like BGS, CGC, SGC, and TAG have similar front centering tolerances for their top grade, but requirements can change, so confirm with each company's latest standards.
The back centering is judged separately and usually allows for more off-centering than the front.

How to Measure Your Card’s Centering

Determining if your card meets the 55/45 standard requires precise measurement. The Midpoint app (available for iOS and Android) can analyze a photo of your card to calculate the exact front and back centering percentages. This helps you make informed decisions before submitting your card for grading.

Other Factors That Affect Grading

While centering is important, it is only one aspect of grading. Corners, edges, and surface condition are also critical for achieving top grades. Even with perfect centering, flaws in these other areas can lower your card’s overall grade.
