About CardCenter Pro

A free centering tool, built by a collector, for collectors who want to know before they pay to grade.

Why it exists

Grading a card costs money and takes weeks, and plenty of collectors have paid to learn that a card was never a 10 candidate because it was cut off-center. Centering is the one grading factor you can measure precisely at home, but doing it with a ruler is slow and imprecise. CardCenter Pro turns a phone photo into an accurate measurement in seconds.

What it does

• Measures left/right and top/bottom centering on the front and back of any trading card: Pokémon, Yu-Gi-Oh!, One Piece, Magic, sports and more.
• Finds the card edges and the printed frame automatically with Auto-align, then lets you fine-tune every line with a loupe.
• Compares the result with the published centering tolerances of PSA, BGS and CGC.
• Exports a PNG report you can share with buyers or keep with your submission notes.

Private by design

Everything runs inside your browser. Your photos are never uploaded, stored or seen by anyone, and there are no accounts to create. Close the tab and your photo is gone. Read the privacy policy for details.

What it isn't

CardCenter Pro is not a grading company and is not affiliated with PSA, Beckett, CGC or any card publisher. Its results are estimates to help you decide, not grades. Grading companies also judge corners, edges and surface, and they make the final call. See our terms and disclaimer.

How it's funded

The tool is free and supported by advertising. Ads never have access to your photos, because your photos never leave your device.
