Why Centering Matters
Centering plays a vital role in determining a card’s grade from professional grading companies. Even if a card is in mint condition, poor centering can drastically reduce its grade and value. With Card Centering Calculator, you can precisely measure centering ratios, ensuring you make informed decisions about submitting cards for professional grading.
Who Should Use Card Centering Calculator
1. Card Collectors: Ensure your trading or sports cards meet professional grading standards, preserving and potentially increasing their value.
2. Sellers & Traders: Verify centering to maximize the worth and appeal of your cards before selling or trading.
3. Buyers: Quickly assess centering on potential purchases to avoid investing in off-centered cards that might lower their grading potential.
Note: Card Centering Calculator focuses exclusively on measuring centering ratios. Keep in mind that professional grading companies like PSA, BGS, CGC, SGC, and TAG also evaluate other factors, including edge wear, surface scratches, dents, dings, and overall condition. This app does not assess these additional grading criteria.

Ratings and Reviews
Works as intended now!
The dev finally got back to me and sorted the issues! Released a new update and now the app finally works as intended!🙂 Thanks Eric!
(Initial Review) Every time I try to measure a card, it will reset when I’m in the last 2 lines to move + when you rotate the image, it doesn’t stay in place either and just goes back to being how it was originally (tilted).
I haven’t actually managed to scan/measure a card once yet and I paid for the app too😭
No reply after sending an email either!
Developer Response ,
Thank you for your feedback! I did reply to your email a few times but didn’t hear back—I hope my messages didn’t get lost in spam.
I wanted to let you know that version 1.9 was released today (March 3rd) and includes a fix for the issue where the centering lines reset unexpectedly. This bug was triggered when all five grading companies were displayed at once and only affected certain devices with narrower screens.
I’m constantly working to improve the app and truly appreciate your feedback. If you have any other suggestions or run into any issues, please let me know—I’d love to make this a 5-star experience for you! You can update your review or just respond to my emails, whatever is easiest!
Good luck with your grading!
