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
