Centering, Corners, Edges, Surface: Check Your Card Like a Grader
Every grader, on every card, from any era, scores the same four things. Learn to check them yourself with a phone light and a steady hand, and you'll know roughly where you stand before you spend a cent on a submission.

The four Pokemon card grading criteria are centering, corners, edges and surface — the same four factors PSA, CGC and TAG each score to arrive at a card's overall grade on a 1-to-10 scale. A card only grades as well as its weakest of the four, so a single damaged corner can cap an otherwise pristine card.
A self-check tells you the range, not the number
Checking your own card at home will not produce an official grade. It's not meant to. What it does is rule out the obvious failures before you commit a non-refundable fee and weeks of turnaround to finding out something you could have seen yourself with a light and a steady hand. Think of it as a pass/fail screen for the worst problems, not a replacement for the grader's actual scoring.
The four criteria, explained
- Centering
- How evenly the printed image sits within the card's border, measured on both axes, front and back. Off-center printing is the most common reason a card misses a top grade.
- Corners
- Sharpness at all four corners. Whitening, fraying or rounding from handling shows up here first, especially on a card that's been sleeved and re-sleeved a lot.
- Edges
- The condition of the card's outer border along all four sides, between the corners. Whitening along an edge from a rough shuffle or a tight sleeve is common and easy to miss under normal light.
- Surface
- Scratches, print lines, indentations and, on holos, foil scuffing across the face of the card. Surface issues are usually the hardest of the four to spot without raking light.
How to check each one at home
-
Centering: measure both axes, both sides
Lay the card flat and compare the border width on the left vs. right, then top vs. bottom, on the front. Flip it and repeat on the back — a card centered on the front is often off-center on the back, and graders check both.
-
Corners: look under a bright, angled light
Tilt the card so light rakes across each corner. Whitening shows as a pale line right at the tip. Check all four; damage often concentrates on the corner that got handled or drawn from most.
-
Edges: run your eye slowly along all four sides
Look for whitening or small chips between the corners, not just at them. A rough sleeve or a tight toploader is a common cause, and it's easy to miss at a glance.
-
Surface: use raking light, not overhead light
Hold the card at an angle under a lamp so light skims across the surface rather than hitting it straight on. Scratches and indentations that are invisible under normal light show up clearly this way.

Write down what you find before you decide
Note the worst issue you saw, not the average. That's the number that will end up limiting the grade.
Why the worst factor decides the grade
A card doesn't get averaged across the four criteria. A card with perfect corners, edges and surface but visibly off-center printing still caps out at whatever centering allows — it doesn't get credit for the other three being flawless. That's why identifying your card's single worst factor matters more than admiring the three that look great.
This is exactly why vintage and modern cards fail for different reasons in practice: vintage WOTC-era cards usually get capped by centering from the era's offset printing, while modern cards are more often capped by handling damage to corners or surface, since factory printing is tighter. The full breakdown of that split is in our modern vs. vintage grading comparison, and the vintage-specific detail is in our vintage grading guide.
Should you submit this card?
Use your self-check to decide, not to predict an exact number.
- No visible issues on any of the four? Worth exploring a submission, especially if the card's real market value supports the fee.
- One clear problem, like an off corner? Expect that to be the limiting factor, and price your expectations against a mid-grade comp, not a Gem Mint one.
- Multiple visible issues? A grading fee is unlikely to pay off here. our sell-or-grade framework can help you decide whether to sell it raw instead.
- Not sure if the card's worth the fee either way? Check its real current market price first, before condition even enters the decision.
FAQ
What are the four Pokemon card grading criteria?
Centering, corners, edges and surface. These are the same four factors PSA, CGC and TAG each evaluate to arrive at an overall numeric grade.
How do I check centering on a Pokemon card myself?
Compare the border width left-to-right and top-to-bottom on the front, then flip the card and check the back the same way. Both sides matter, and a card can look centered on one side and not the other.
Does a card get an average score across the four criteria?
No. The weakest of the four factors typically limits the overall grade, so one bad corner can cap a card even if everything else looks flawless.
What's the best way to check for surface scratches at home?
Use raking light — tilt the card under a lamp so light skims across the surface at an angle instead of hitting it straight on. Scratches and indentations that are invisible under normal overhead light usually show up this way.
Will checking my card at home tell me the exact grade I'll get?
No. A self-check rules out obvious failures and tells you the rough range, not the precise number a grader will assign. It's a screening step before you commit to a fee, not a substitute for the actual review.
