Understanding the Basics of Card Centering Analyzer

A centering ratio quantifies how evenly the printed image sits between opposite card borders. Calculate it as (smaller border ÷ total of both borders) × 100, then display it as X/Y (for example, 55/45). Card centering analyzers let you upload or scan card images; their AI or manual guides detect the edges and compute left/right and top/bottom ratios. For collectors preferring rulers, see our step-by-step guide for collectors.

FAQ

What does 60/40 mean?
One border is 60% of the total side length, the opposite border is 40%.
Do I need both front and back images?
Front-only gives a partial view; dual-side analysis offers a complete assessment.
Why do different tools give different ratios?
Variations in detection algorithms and manual-adjust options lead to slight differences.
Can I use a phone camera?
Yes—phone capture is fully supported and often more convenient for quick scans.
What if my card has faint borders?
Use higher image quality or manual guide correction if low-contrast edges reduce accuracy.
