Centering Check: TCG Card Tool

Centering Check is your premium pocket-sized tool for measuring card centering with pixel-perfect precision and getting instant grade estimates.

Simply snap a photo or upload a screenshot of an online listing. Instead of worrying about perfect camera angles, our custom AI Auto-Detection Method instantly transforms your image into a flat, bird's-eye view, fixing any perspective distortion automatically. You have complete control to ensure absolute accuracy by manually adjusting the borders, giving you a precise look at the card's true centering in seconds.

Key Features:

✅ Evaluate Online Listings Instantly: Take a screenshot of any online listing and upload it directly. Our AI Auto-Detection Method removes the angle distortion and auto-detects all borders, letting you check if the card has a 10 centering grade before you even buy it.

✅ Ultra Precision Scan: Check every border at full resolution and zoom in up to 8x, for more than twice the precision of a standard scan. Confirm each border pixel by pixel before you decide what to send in for grading.

✅ Batch Ranking: Select multiple photos or shoot cards one after another. Every card is measured, saved to your collection log, and ranked by centering in a single pass, so you find the grading candidates immediately.

✅ Pinch-to-Zoom: Zoom in on your card's edges to make pixel-perfect micro-adjustments before finalizing your measurements.
