Understanding Sports Cards Centering: What It Is, Why It Matters, and How to Measure

What Does Good Centering Look Like on Sports Cards?

Good centering means the card’s image and borders are as evenly spaced as possible on all four sides. The goal is for the printed content to be visually centered. Modern cards from Topps, Panini, Upper Deck, and others can still have off-center printing or cutting, even with advanced manufacturing. Chrome and refractor cards make centering issues and edge wear more visible. Always inspect both the front and back centering, as both are graded.

Why Centering Matters for Grading

Centering is a key subgrade for all major grading companies, including PSA, BGS, CGC, SGC, and TAG. Poor centering can significantly lower your card’s overall grade, even if the corners, edges, and surface are flawless. Each grader has specific, published standards for what centering qualifies for each grade level. These standards can change, so always check the latest requirements from your chosen grader before submitting.

How to Measure Card Centering

• Visually inspect borders on all four sides for evenness.
• Measure the thickness of each border (top, bottom, left, right) to compare ratios.
• Use a digital tool like the Midpoint app (iOS and Android) to analyze a photo of your card. The app detects inner and outer borders and calculates exact front and back centering percentages (for example, 55/45).

Knowing your card’s exact centering ratio before submission helps you make informed grading decisions. Remember, centering is only one aspect of grading - corners, edges, and surface condition also impact the final grade.

Tips for Evaluating Centering Before Submission

• Check both front and back centering, as both are graded.
• Be aware that some print runs have consistent centering flaws.
• Always confirm the latest published centering standards from your grading company.
• Measure your card’s centering in the Midpoint app for a precise assessment before sending it in.
