Card Caliper Autor: frighten

Card Caliper helps collectors inspect left/right and top/bottom card centering without downloading photos or sending them to another service.

Right-click a trading-card image and choose Card Caliper. The extension opens a focused measurement view with adjustable outer-card and inner-print guides, centering percentages, zoom and pan controls, image rotation, an optional grid, and configurable guide styling.

Card Caliper can estimate the outer card edge and printed border locally. Automatic results are a starting point, not a professional grade; every guide remains manually adjustable for glare, sleeves, holders, perspective, and unusual card designs.
