BellyTCG's centering tool analyses front and back card photos separately, measuring left/right and top/bottom centering ratios. It estimates grades for PSA, BGS, CGC, TAG, and SGC. PSA 10 requires 55/45 centering or better on the front face. BGS Pristine 10 requires 50/50. CGC Gem Mint 10 requires 55/45 front and back.

Back face thresholds are more lenient: PSA 10 allows up to 75/25 on back. Grades are estimates — centering is one of four grading criteria.

Common Questions

What grading companies does BellyTCG estimate for?

The centering report estimates grades for PSA, BGS, CGC, TAG, and SGC — covering both front and back face measurements separately. Each grader uses slightly different thresholds. PSA 10 requires 55/45 front and 75/25 back.

Does it check both front and back of the card?

Yes. You upload separate photos for the front and back face. The report shows measurements and grade estimates for each face independently, plus a combined worst-case estimate shown in the grade tiles.

How accurate are the grade estimates?

The estimates are based on centering ratios only. Grading companies also assess corners, edges, and surface — factors the tool cannot measure from a photo. Use it as a first filter to identify clearly off-center cards before purchase or submission.

Can I share my centering report?

Yes. Every report generates a shareable link and a downloadable composite image — card photos, measurements, grade estimates, and corner crops — with BellyTCG branding. Shared links work without login.
