Card Centering Checker

Read full description

Card Centering Checker is the fastest way to estimate the centering grade of any trading card before you submit it. Built for serious collectors of PokΓ©mon, sports, Magic, and TCG cards who refuse to throw $25–$75 at a grading service hoping for a 10. Snap a photo. Drag 8 alignment bars. Get an instant PSA, BGS, and CGC centering grade β€” all three scales, side by side, calibrated against each company's official tolerances. WHY COLLECTORS LOVE IT β€’ Real grading math β€” not a guess. Calibrated to PSA's 55/45 front, 75/25 back rule, BGS sub-grades, and CGC tolerances. β€’ 8 draggable bars give you pixel-perfect alignment β€” pinch to zoom in tight on the borders. β€’ Front + back support. The worse side determines the grade, just like the real graders. β€’ Beautiful 1080Γ—1080 share images for eBay listings, Reddit, Instagram, and group chats. β€’ Premium PDF reports with QR codes for buyers and PWE trades. β€’ Organized library β€” collections, filters, search, sort by grade. β€’ Build submission lists before you ship to PSA, BGS, or CGC. ONE PAYMENT. YOURS FOREVER. $6.99 once. No subscriptions. No ads. No data harvesting. Every future feature included. PRO UNLOCKS β€’ Unlimited centering checks β€’ Unlimited collections β€’ PSA + BGS + CGC grading scales β€’ Clean share images (no watermark) β€’ Pro-level editor zoom WHAT FREE GETS YOU β€’ 3 collections, 50 saved scans β€’ Full PSA centering grades, free forever β€’ Watermarked share images PRIVACY FIRST Photos never leave your device unless you choose to share them. No accounts. No cloud. No tracking. DISCLAIMER Card Centering Checker provides centering estimates only. Final grades from PSA, BGS, and CGC depend on additional factors including surface, edges, corners, and print quality. Results are an indicator, not a guarantee. Pre-grade like a pro. Stop submitting your bad ones.
