Understanding HGA Centering Standards and Tolerances

HGA (Hybrid Grading Approach) uses computer-assisted analysis to assess card centering on both the front and back. To achieve top grades, cards must have even borders. Always confirm HGA's current published standards and measure your card's exact centering with Midpoint before submitting.

How HGA Grades Centering

HGA evaluates centering as one of the key subgrades, using a 1-10 scale. Both the front and back of the card are analyzed, and computer-assisted tools help ensure accuracy. Even borders are required for the highest centering grades. HGA's exact centering ratio requirements can change, so always reference their latest published guidelines before submitting cards.

Front and Back Centering Requirements

Top centering grades require nearly even borders on all sides, both front and back.
Cards with visible centering shifts may receive lower subgrades, even if other aspects are strong.
HGA may have different tolerances for front and back centering, so review their current standards before submission.

How to Measure Your Card's Centering

To know how your card might perform on HGA's centering subgrade, measure its exact centering percentages. The Midpoint app (available on iOS and Android) detects the borders from a photo and calculates precise front and back centering ratios (like 55/45). This helps you compare your card's centering with HGA's published standards before submitting.

Other Factors in HGA Grading

While centering is important, HGA also considers corners, edges, and surface condition for the overall grade. Even with perfect centering, flaws in these areas can lower a card's grade. Always inspect all aspects of your card before sending it in for grading.
