Collector guide / Direct answer
How can you measure Pokémon card centering and wear?
Flatten the camera perspective first, then measure border ratios and visible whitening while keeping every observation visible beside the suggested result.
Open Grade
THE USEFUL ANSWER
What to look for
MoonTCG uses geometry and image measurements for collector guidance. It deliberately separates that photo-based workflow from the PSA grade label attached to a physical slab in the Vault.
WHY MOONTCG FITS
Perspective correction before centering measurement.
Visible corner and edge wear percentages.
Transparent suggested subgrades and confidence.
Scope and limitations
Camera measurements are not professional grading opinions and cannot inspect hidden damage, authenticity, print defects, or every surface issue.
