Centering Pre-Grader

Capture or upload a straight-on photo, mark the card’s outer corners to straighten it, then fit the box to the inner frame. You get left/right and top/bottom centering ratios and the best PSA grade the centering alone would allow. Everything runs in your browser.

Guide only. This tool estimates centering from a photo and is affected by lighting, angle and lens distortion. It does not judge corners, edges or surface, which also decide a grade. Treat the result as a rough indication — PokeHive accepts no responsibility for any errors or decisions made on the basis of it. The only way to get an accurate, authoritative grade is to submit the card for in-person grading with PSA, BGS or CGC. See how card grading works.

Guide only. Estimate from your alignment — centering is one of four PSA sub-grades (corners, edges, surface too), and the reading is affected by lighting and camera angle. PokeHive takes no responsibility for errors. Only an in-person submission to PSA / BGS / CGC gives an accurate grade. Not affiliated with PSA.

Frequently asked

Does PokeHive give an official card grade?
No. The Pre-Grader only estimates centring from a photo and shows the highest PSA grade that centring alone would allow. Corners, edges and surface also decide a grade, and only an in-person submission to PSA, BGS or CGC is authoritative.
Does my photo get uploaded anywhere?
No. The image is processed entirely in your browser — nothing is sent to a server unless you separately choose to save a card photo to your collection.
What makes a good scan?
A straight-on shot that fills the frame, on a plain contrasting background, in even light with no glare, at least ~1000px wide. Camera angle and lighting are the biggest sources of error.
Why does my Mint-looking card only show PSA 8 or 9?
Centring caps the grade. If the border is off to one side, the card can't reach PSA 10 no matter how clean the corners and surface are. Under a loupe, small centring and corner issues show up that the eye misses.
