Check Card Centering on eBay Listings
Measure a card's centering from the listing photos - before you bid:
Why centering matters when you buy a card
Centering is one of the biggest factors in a card's grade. An off-center card grades lower than an otherwise identical copy, and a lower grade means a lower price - whether you are buying a graded card or a raw one you plan to submit.
The catch is that listing photos rarely mention centering, and a card can look fine at a glance while sitting at 60/40. Measuring it yourself from the photos the seller already provided takes under a minute, and it works the same whether you are looking for a clean raw copy or screening grading candidates.
Open the listing's card photo
Open the listing and click the card photo to bring up the full-size view. Larger photos give a better measurement, so always start from the biggest version the listing offers.
Copy the photo's address
Right-click the photo and choose "Copy image address" to put its link on your clipboard. You can also simply drag the photo itself out of the listing instead of copying the address.
Paste it into the tool
Go to the Centering Check homepage and press Ctrl+V (or Cmd+V on a Mac), or drag the photo straight into the upload box. The tool tries to fetch the photo and measure the card for you.
Read and adjust the results
Adjustable borders appear on the card, along with top/bottom and left/right ratios with their estimated PSA, CGC, BGS and TAG centering subgrades.
How to get the best measurement from a listing photo
- Pick the most straight-on photo in the listing.
- Both raw cards and slabbed cards in listing photos work, so you can screen graded copies too.
- Front and back can each be checked: run the back photo separately if the listing shows one.
- Photos need to clearly show all four edges of the card for a precise measurement.
What you get, and what to do next
Every check gives you the left/right and top/bottom ratios plus the estimated centering grade of the card by referring to published grading standards of PSA, CGC, BGS and TAG. To see each company's exact tolerances and what a given ratio is worth, head to the Grading Standards page. Refer to the centering guide if you want to understand how centering measurement works in practice.
