Whether you’re working with Pokémon, One Piece, Lorcana, or sports cards like baseball, basketball, and football, the app provides real-time centering measurements (e.g., 55/45 or 60/40) and displays the highest potential grades from major grading companies, including PSA, BGS, SGC, CGC, and TAG.

Key Features


— Card Scanner With Auto Centering Detection

Scan or upload your card, and let AI automatically calculate its centering ratios.

Instantly see the best possible grades from PSA, BGS, CGC, SGC, and TAG as you adjust centering ratios, helping you choose the grading company that will give your card the highest grade based on centering.


— Front & Back Side Grading

Measure centering for both the front and back of your card, as different grading standards often apply to each side.

An all-in-one handbook for the official centering standards from PSA, BGS, CGC, SGC, and TAG.


— Advanced Settings & Customizations

Tailor auto-detection settings, grading preferences, colors, and more to suit your specific needs.


— Off-Center Visualization Guide

Select any centering ratio (e.g., 65/35 or 75/25) and view a visual representation of an off-centered card. This feature helps you quickly assess and exclude poorly centered cards without needing to scan each one.


— Compatible With All Cards

From TCG cards like Pokémon, One Piece, Yu-Gi-Oh!, Lorcana, and Magic: The Gathering to sports cards like baseball, basketball, and football, this app works with any card type you need to grade.

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.

Love it

But how do you purchase the premium version I don’t see the option in the app only tip jar option. If u could direct me on how to obtain the premium I would love to purchase it thank you


UPDATE: after having paid the $4 (worth every cent) it’s perfect for guessing ur centering of the card,would highly suggest getting platform to take 0degree tilt perfect flat pictures to make sure ur centering is good. Otherwise it’s the best app in the market for centering in 20days I’ll comeback to update since I did use this app to get the centering on a Moonbreon which is in grading at the moment.

Developer Response ,

Hey hhr2009! You can purchase premium on the "more" tab. Feel free to reach out to me through the app if you need any additional assistance! Thanks! 🙏🏻

Best App, Best Dev

The app is great. It’s simple, intuitive and very powerful. Paying for pro is worth it in my opinion. It has all the big time graders and it automatically updates the possible grade as you’re checking the centering. Even if you stick with the free version it’s really helpful and has a section for grading methodology.


The dev is very responsive and quick with updates. One of the best app experiences I’ve had on iOS hands down. Will be recommending this app to all my fellow collectors.

Thanks Witecastle! I really appreciate your review!

Great pre-grading tool

I was searching for a quick and accurate way to measure the centering of my Pokémon cards before submitting them to PSA, and this app has been perfect for that. It makes it much easier to distinguish between subtle differences like 55/45 and 60/40 centering. The developer has also been incredibly responsive to feedback and open to suggestions, which gives me confidence that the app will keep improving. Looking forward to future updates!

Developer Response ,

Thanks for your review TacomaLynne! I'm glad the app is helping with your Pokemon pre-grading. 🙂
