What to check

My Pikachu 58/102 with the 25th anniversary stamp, front

1 · Front

Front borders

Measure from the card edge to the yellow frame. On full arts, use the line where the border meets the art.

The back of my Gengar Prime, blue border

2 · Back

The back counts

PSA allows about 75/25 on the back for a 10. A blue border that is clearly thicker on one side can cost the grade.

3 · Photo

Shoot it flat

Phone parallel to the card, even light, plain background. Take it out of the sleeve to kill the glare.

Get a measurement you can trust

Take a straight photo

Lay the card flat and hold your phone right above it. Plain background, even light, no glare.

Tap Auto-align

It finds the card edge and the printed frame, and places all 8 lines for you. Then give them a quick look.

Drag slowly for fine moves

Move your finger slowly and the line moves at 1/4 speed. It stays put when you lift your finger.

Lines snap to edges

Drag a line near an edge and it sticks on it, like a magnet. Keep moving to pull it off.

Green means sure

After Auto-align, any line it is not sure about turns amber or red. Tap Check and it takes you right to it.

Pinch to zoom

Pinch or double-tap the photo to get close to an edge. Drag with one finger to look around.

Check all 4 corners

Tap Check corners to see every corner up close. Each line should sit right on its edge.

Nudge 1 pixel, undo anytime

Tap a line, then use the arrows to move it one pixel. Made a mistake? Tap undo.

Card far away or tilted?

Tap Crop and put the 4 dots on the card's corners. It crops and straightens the photo at full resolution.

FAQ

What centering does a Pokémon card need for a PSA 10?+

PSA publishes about 55/45 on the front and 75/25 on the back for a Gem Mint 10. BGS 10 and CGC Pristine are stricter. See the centering standards guide.

How do I check centering on a full art Pokémon card?+

Place the outer guides on the card edges and the inner guides where the thin border ends and the artwork starts. If Auto-align is not sure, it lets you place the cyan guides by hand. Use the loupe to check each line.

Does it work on Japanese Pokémon cards?+

Yes. The method is the same for English, Japanese and other languages. Measure front and back separately.

Should I check centering before buying a single?+

Yes. Ask the seller for straight-on photos of the front and back and run them here. Centering is the one flaw you can judge well from a photo.

Are my photos uploaded?+

No. The tool runs in your browser. Your photos and reports never leave your device.

Is this an official grade?+

No. It is a digital estimate to help you decide. Corners, edges and surface count too, and the final grade always comes from the grading company.
