CenterMint: Card Centering

Check your card's centering before you send it for grading.

CenterMint helps collectors measure the left/right and top/bottom border ratios of trading cards and sports cards. Photograph a card or import an image, inspect the suggested outer and inner frames, then confirm or adjust the edges before reading the result.

SEE WHAT YOU ARE MEASURING
• Inspect the card edge and printed inner border directly on the photo.
• Adjust individual edges with a magnifier and fine controls.
• Compare centering ratios with the reference thresholds in the app.
• Keep front and back scans together in a searchable local collection.
• Share a centering image with your measurements.

PRO TOOLS FOR YOUR COLLECTION
An optional CenterMint Pro purchase unlocks detailed reports, batch image and CSV exports, saved editing presets and an ad-free experience. Available plans and local prices are shown in the app. Subscription plans renew automatically until canceled; manage them in your Apple account settings.

Card analysis runs on your device. No account is required. Card photos and measurements are not automatically uploaded. Sharing and exporting are actions you choose.

The app supports English, Japanese, Korean, Vietnamese, Simplified Chinese and Traditional Chinese.

Detection suggestions need review. Lighting, sleeves, perspective and card design can affect the detected frame. Full-art cards may not have a measurable printed inner border. CenterMint estimates centering only, not surface, corners, edges, authenticity or a professional grade. It is an independent tool and is not affiliated with Pokémon, PSA, Beckett or CGC.
