Why Centering Matters

Centering is one of the most important factors in a card's professional grade. Even a card in perfect condition can receive a lower grade and lose significant value due to poor centering. Card Centering Calculator Pro helps you measure centering ratios accurately, so you can make informed decisions before spending money on grading submissions.

Who Should Use Card Centering Calculator Pro

Collectors: Make sure your cards meet grading standards before submitting, saving time and money.

Sellers & Traders: Verify centering to maximize the value of your cards before listing or trading.

Buyers: Assess centering on potential purchases to avoid investing in cards that won't grade well.

Note: Card Centering Calculator Pro measures centering ratios only. Professional grading companies like PSA, BGS, CGC, SGC, TAG, and ACE also evaluate edges, corners, surface scratches, and overall condition. This app does not assess those additional factors.
