Centering Check · Submission Pre-Screen
Card Centering Tool
Upload a clear, flat photo of the front of your card. We'll estimate left/right and top/bottom centering so you can sanity-check it before paying to grade. This is a pre-screen — not a guaranteed grade prediction.
Upload front image
Best results: bare card (no sleeve), shot straight-on, on a contrasting background, filling most of the frame.
Before you upload
- You confirm you have the right to use this image and that it is not unlawful, infringing, or abusive content.
- Centering analysis is assistive only. It is not a grade prediction and does not replace the judgment of PSA, BGS, SGC, or CGC.
- Analysis runs in your browser. The raw image is not uploaded to GradeYield servers or stored by us — only the resulting score and label are saved if you explicitly attach the analysis to a card.
See our Terms and Privacy Policy for the full upload terms.
How to read this
The green dashed box is the detected outer card edge. The solid indigo box is the detected inner design border. PSA centering is measured between those two — closer to 50/50 is better.
Image quality, angle, sleeves, and full-bleed designs (Topps Chrome refractors, etc.) all affect accuracy. Treat this as a sanity check, not a grading guarantee.
Pre-screen guidance only. Not a grade prediction. PSA, BGS, SGC, and CGC use subjective standards we cannot replicate. Learn more.
