Card Centering Guide
Measure card centering before you submit, sell, or buy
Is My Card Centered? is a free, guide-based card centering tool for Pokemon cards, sports cards, and other TCGs with measurable borders. Upload or capture a card photo, correct perspective when needed, place the guides, and compare the visible left/right and top/bottom border balance.
Use the result as one part of a hands-on card review—not as a promised grade. Corners, edges, surface, printing, authenticity, the source photo, and grader judgment can all affect a final outcome.
What is card centering?
Card centering describes how evenly the printed design sits between opposite physical edges. A collector usually checks two axes: left versus right and top versus bottom. Equal visible borders are close to 50/50; a wider border on one side moves that axis toward a ratio such as 55/45 or 60/40.
A ratio makes a visual difference easier to describe, but it is only as reliable as the boundaries chosen. Place guides on the true card edge and a repeatable printed-border edge rather than a sleeve, shadow, glare line, or artwork detail.
How to use this card centering tool
- Upload a card image or capture one with your camera.
- Crop away extra background, or use perspective correction when the photographed card is visibly angled.
- Align the Outer guides to the physical card edges and the Inner guides to a repeatable printed-border boundary.
- Open the Result section to review both the left/right and top/bottom estimates.
- Recheck the guides and reject the photo when its edges do not support a clear measurement.
For a cleaner starting image, photograph the card straight on, keep all four edges visible, use even lighting, and avoid a sleeve or holder that hides the edge. See the photo setup guide for a fuller evidence checklist.
Understanding the centering result
- 50/50 means the two visible borders on that axis measure equally.
- 55/45 means one border takes about 55% of their combined width and the opposite border about 45%.
- 60/40 means the wider border takes about 60% of the pair and the narrower border about 40%.
Read each axis separately and keep its direction: 60/40 left-to-right is different from 40/60. The centering ratio guide shows the formula, worked examples through 70/30, and the measurement limits behind the estimate.
Common card centering questions
- Can I check Pokemon, sports, and other TCG cards? Yes, when the card has visible physical edges and a repeatable printed boundary on the axis being measured.
- Is the centering tool free? Yes. The photo measurement workflow and manual calculator are available without an account.
- Does a centering ratio determine the final grade? No. Centering is one grading consideration, and the tool does not authenticate a card or guarantee a PSA, BGS, TAG, CGC, or other grading outcome.
- Does the site save my card photo? Centering images are processed in your browser. Anonymous measurement metadata may be logged, but centering logs do not include the uploaded image, filename, card name, account identifier, or a persistent user identifier.
Choose the right centering workflow
Use the Centering Guide for detailed measurement methods and ratio interpretation. If you already have ruler, caliper, scan, or image-editor measurements, use the Manual Centering Calculator instead of aligning a photo. The Learning Center keeps those resources separate from broader condition and submission questions.
