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.

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.
