Card Inspection Guide

Measure card centering before you submit, sell, or buy

Is My Card Centered? is an independent inspection workspace for collectors who want a clearer read on trading-card centering and grading risk before making a decision. The Centering tool lets you upload or capture a card photo, correct perspective when needed, place outer and inner guides, and review left/right plus top/bottom ratios from the visible card borders.

The tool is built for practical pre-submission review, not for promising a grade. Centering is only one part of condition, and grading outcomes can also depend on corners, edges, surface quality, printing, authentication review, grader judgment, and the quality of the photo you inspect.

What card centering means

Centering compares the printed border on opposite sides of a card. A perfectly balanced card is close to 50/50 left-to-right and 50/50 top-to-bottom. If one side has a wider border, the ratio moves away from center, such as 55/45 or 60/40.

Those ratios are useful because they turn a visual impression into a measurement you can compare across photos. They still depend on whether the guides are placed on the true card edge and printed border, which is why manual adjustment remains important.

Why photo quality changes the result

A tilted photo, cropped corner, dark sleeve edge, glare line, or thick background shadow can make the visible border look different from the card itself. Perspective correction helps, but it cannot recover details that are missing or hidden in the photo.

For the best read, photograph the card straight on, keep all four edges visible, use even lighting, and avoid sleeves or holders when they obscure the real edge. If a photo is uncertain, treat the result as a risk signal rather than a final answer.

What the app can and cannot predict

The app can estimate visible centering ratios, help you compare front and back photos, and make it easier to spot when a card deserves closer review. It cannot authenticate a card, see defects outside the photo, account for every grading-company standard, or guarantee any PSA, BGS, TAG, CGC, or other grading outcome.

Use the result alongside hands-on inspection, current grading-company instructions, and your own risk tolerance before submitting or buying a card.

Privacy-safe centering logs

The Centering workflow processes uploaded images in your browser for measurement. Completed centering checks may save anonymous measurement metadata, such as image dimensions, guide positions, detection confidence, feature use, and final ratios, to improve guide placement and measurement quality.

Those centering measurement logs do not include uploaded card images, filenames, card names, account identifiers, or persistent user identifiers.
