Centering — The Invisible Value Killer
A card's centering can be the difference between a PSA 10 and a PSA 8, and the price difference can be thousands of dollars. Here's how to understand, measure, and evaluate centering.
What Is Card Centering and Why It Matters
Centering refers to how evenly a card's artwork and borders are aligned within the card's physical dimensions. A perfectly centered card has equal border widths on the left and right sides, and equal border widths on the top and bottom. In practice, almost no card is perfectly centered — printing and cutting processes introduce slight offsets that create uneven borders. Centering matters enormously because it's one of four primary criteria grading companies use to evaluate condition (along with corners, edges, and surface), and it's often the deciding factor between grade tiers. A card with perfect corners, edges, and surface can still receive a PSA 8 or lower if the centering is skewed enough. The financial impact is dramatic: a card that would be worth $500 at PSA 10 (60/40 or better centering) might drop to $200 at PSA 9 (65/35) and $80 at PSA 8 (80/20) — all because of border alignment that most people wouldn't notice at arm's length. Understanding centering is essential for anyone considering professional grading or buying raw cards at premium prices.
How Grading Companies Evaluate Centering
PSA evaluates centering on both the front and back of the card, using slightly different thresholds for each side. For a PSA 10 (Gem Mint), front centering must be 60/40 or better and back centering must be 60/40 or better. For PSA 9 (Mint), front centering must be 65/35 or better and back centering 75/25 or better. PSA 8 (Near Mint-Mint 8) allows front centering up to 75/25 and back centering up to 80/20. Below PSA 8, centering becomes less relevant because other condition issues typically dominate the grade. CGC uses a similar but not identical scale — CGC 10 (Pristine) is even stricter than PSA 10, requiring 50/50 centering on the front. BGS (Beckett) evaluates centering as one of four sub-grades (along with corners, edges, and surface) and uses a 10-point scale for each, with the overall grade being the lowest of the four sub-grades — meaning off-center cards cannot achieve BGS 10 regardless of how perfect the other three categories are. When buying raw cards for potential grading submission, measure centering before purchasing to avoid spending grading fees on cards that can't achieve your target grade.
How to Measure and Evaluate Centering at Home
You don't need professional equipment to evaluate centering — a ruler or digital calipers and good lighting are sufficient. Start by placing the card face-up on a flat, well-lit surface. Measure the left and right border widths to the nearest 0.5mm and calculate the ratio: (wider side) / (narrower side + wider side). If the left border is 3mm and the right border is 2mm, the ratio is 3/(3+2) = 60% — exactly at the PSA 10 threshold. Repeat for top/bottom borders. For the back, flip the card and repeat the same measurements. A digital centering tool or centering overlay (printable templates available online) can speed up this process by letting you visually compare the card against known ratios. When evaluating cards for purchase, photos often exaggerate or minimize centering depending on the camera angle — always ask the seller for a straight-on photo taken parallel to the card surface, not at an angle. Some online marketplaces and Pokex list centering information for high-value cards, taking the guesswork out of pre-submission evaluation. If you're considering submitting multiple cards for grading, pre-screen all of them for centering first — eliminating off-center cards before submission can save hundreds of dollars in non-refundable grading fees.
Часто задаваемые вопросы
01 Can off-center cards be fixed?
No. Centering is determined by the factory cutting process and cannot be altered without trimming the card, which is illegal in graded collecting and detectable by grading companies. Trimmed cards receive a 'trimmed' designation that eliminates most of their value. Always buy the best-centered raw card you can find rather than hoping to improve centering later.
02 Does back centering matter as much as front centering?
For grading, both front and back centering matter, but front centering is more visible and more commonly checked by buyers. For PSA, the back centering threshold is more lenient (60/40 for PSA 10, 75/25 for PSA 9). For CGC 10 (Pristine), back centering must also be 50/50, making it the strictest grader for both sides.
03 Why are some Pokémon cards naturally off-center?
Printing and cutting are mechanical processes with inherent variation. The large sheets of cards are printed and then cut into individual cards using industrial guillotine cutters that can shift slightly between cuts. Vintage cards from the WotC era are notoriously variable in centering because quality control was less strict. Modern cards have better centering on average, but even current sets have 5–10% of cards that grade below PSA 9 due to centering alone.
04 What does 60/40 centering look like?
A 60/40 center split means one border is 60% of the total border space and the other is 40%. Visually, this looks like a slight but noticeable asymmetry — the artwork appears shifted slightly toward one side. It's subtle enough that many casual collectors don't notice it, but obvious enough that an experienced grader or collector can spot it immediately on inspection.
