Card Centering Calculator

TCG & Sports Card Grading Tool

Card Centering Calculator is the ultimate tool for trading card game (TCG) and sports card collectors who plan to get their cards graded. Whether you’re working with Pokémon, Yu-Gi-Oh!, Magic: The Gathering, or sports cards like baseball and basketball, Card Centering Calculator lets you accurately measure your card’s centering ratios in real-time (e.g., 55/45 or 60/40), while displaying the best possible grades it could receive from major grading companies like PSA, BGS, and CGC. Is your card worthy of a 10?

Key Features:

Precise Ratio Measurements Every card has a unique design, so Card Centering Calculator allows you to manually place measurement guides for each side. You can zoom in for precise adjustments, ensuring accurate centering ratios.

Grade Comparisons See the best possible grade from PSA, BGS, and CGC as you adjust the centering ratios, allowing you to compare and decide which grading company will give your card the highest grade based on centering alone.

Front & Back Side Grading The app distinguishes between front and back side grading, as different grading standards apply to each side.

Grading Standards View the official grading criteria from PSA, BGS, and CGC, so you can understand how each company evaluates card centering based on their unique standards.

Off-Center Visualization Guide Our visual guide lets you select any centering ratio (e.g., 65/35 or 75/25) to see what an off-centered card looks like. This helps you quickly assess and eliminate off-centered cards without the need to scan and measure each one.

Compatible with All Cards Whether it’s TCG cards like Pokémon, Magic: The Gathering, and Yu-Gi-Oh!, or sports cards such as baseball, basketball, and football, Card Centering Calculator works with any card type you need to grade.


Why Centering Matters

  • Centering is a critical factor in determining a card’s grade from professional grading companies like PSA, BGS, and CGC. Even if a card is in mint condition, poor centering can significantly lower its grade and value. With Card Centering Calculator, you can accurately measure your card’s centering, helping you decide if it’s worth submitting for professional grading.


Who Should Use Card Centering Calculator

  • Card Collectors: Ensure that your trading or sports card collection meets professional grading standards by checking centering, helping you preserve and potentially increase your card’s value.

  • Sellers & Traders: Verify your card’s centering before selling or trading to maximize its worth and appeal to buyers.

  • Buyers: Quickly assess the centering of potential purchases to avoid investing in off-centered cards that could lower their value or grading potential.


Note: Card Centering Calculator focuses solely on measuring the centering ratios of your card. Please note that professional card grading companies like PSA, BGS, and CGC evaluate additional factors beyond centering, including edge wear, surface scratches, dents, dings, and overall card condition. This app does not assess or provide feedback on these other grading criteria.
