Centered Cardboard

Centered Cardboard helps you pre-grade trading cards by making centering and alignment quick, consistent, and easy to understand.

Use your camera or import photos to check a card’s position with clear, visual tools built for accuracy:

• Live centering feedback with color-coded ratio indicators so you can instantly spot great, medium, or poor centering
• Skewed Measuring to help measure rotated inner borders more accurately
• Exact Distances for precise inner-to-outer border spacing
• Gyro leveling crosshair to keep your camera level for more reliable results
• Gyro calibration button to level the camera to any surface
• Outline guide overlays to frame your card cleanly and reduce guesswork
• Photo filters to boost contrast and make edges and guides easier to see in any lighting
• Up to 100× zoom for precise positioning and fine adjustments
• Flexible image input: capture with the camera or upload from your Photos/Files
• Side-by-side exports to share front and back results in one clean image
• Cardboard History library to save, search, and revisit your exported cards locally
• One-tap sharing so you can save or send results instantly
