PreGrade Ultra uses perspective correction to reduce the impact of camera angle on your centering measurements. **PERSPECTIVE CORRECTION** Other centering apps measure your photo as-is. If your camera is even slightly angled, your measurements can lose accuracy. PreGrade Ultra uses homography-based perspective correction to mathematically flatten your card to its true 63×88mm dimensions before measuring borders — centering analysis powered by computer vision. **PRECISION CENTERING ANALYSIS** - Measure left/right and top/bottom centering ratios - Millimeter-level border measurements - Front and back analysis with separate thresholds - Visual edge detection confirms your guide placement - Detect clockwise and counterclockwise print tilt **7 GRADING COMPANIES** Centering grades from PSA, BGS, CGC, TAG, SGC, ACE, and AGS. Every company has different thresholds — see which grade your card may qualify for at each one, with full threshold breakdowns. **CROSS-GRADE OPPORTUNITIES** Already have a graded card? See which companies may give a higher centering grade. The Understand tab highlights your potential best market-value grade at a glance. **MARKET PRICING** Look up active eBay listings for any Pokémon card. See current asking prices for raw and graded cards across most major grading companies. **BUILT FOR COLLECTORS, NOT ADVERTISERS** No ads. No banner spam. PreGrade Ultra is a tool built by a collector, for collectors. 3 free grading sessions included. Unlock unlimited access with a one-time Pro upgrade. **IMPORTANT:** PreGrade Ultra measures centering only. Card grading involves surface condition, corners, edges, and print quality — factors that cannot be assessed from a photo. Results are estimates and are not guaranteed to match any grading company's official assessment. PreGrade Ultra is not affiliated with, endorsed by, or sponsored by any grading company. Pokémon is a trademark of Nintendo, Creatures Inc., and GAME FREAK Inc. eBay is a trademark of eBay Inc. All company names and grading scales are trademarks of their respective owners.
