## Description

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

Use your camera or import photos to examine cards with clear visual tools designed for accuracy:

• Live centering feedback with color-coded ratios  
• Grading score estimates based on leading grading-company standards  
• Corner Grading for recording all four front and back corners  
• Tilted Measuring for cards with rotated inner borders  
• True Distance measurements for exact border spacing  
• Adjustable outline guides for accurate card alignment  
• Gyro crosshair and calibration tools for level camera positioning  
• Photo filters that improve edge visibility in difficult lighting  
• Up to 100× zoom for precise positioning and fine adjustments  
• Camera, Photos, and Files image support  
• Separate or combined front and back scores  
• Side-by-side exports for sharing both sides in one image  
• Cardboard History for saving, searching, editing, and revisiting exports locally  
• One-tap sharing for quickly saving or sending results  

Centered Cardboard gives collectors a clear, repeatable way to inspect cards before submitting them for grading.
