Card Centering Calculator is the ultimate tool for measuring your card's centering ratios before grading. Whether you collect Pokémon, One Piece, Lorcana, Yu-Gi-Oh!, Magic, baseball, basketball, football, or other trading and sports cards, the app helps you quickly measure centering, compare grading standards, and decide if your card may be worth submitting. Scan or upload a card image to calculate real-time centering ratios, such as 55/45 or 60/40, and instantly compare the highest potential centering grades from major grading companies including PSA, BGS, SGC, CGC, TAG, and ACE. Wondering if your card has centering worthy of a Gem Mint 10? Measure it before you submit. --- Card Scanner With Auto Centering Detection --- Scan or upload your card and let the app automatically detect the card edges and calculate centering ratios. --- Precise Ratio Measurements --- Manually adjust measurement guides on each side of the card for precise centering calculations. Use zoom for ultra-accurate adjustments and fine-tuning. --- Measure in Pixels, Millimeters, or Inches --- Switch from percentages to real measurements. View each border's width in pixels, millimeters, or inches to double-check against calipers or calculate centering your own way. --- Saved Cards --- Save cards to your collection and come back to them later. Add tags, filter your saved cards, and keep track of cards you may want to grade, sell, trade, or review again. --- Perspective Fix Tool --- Correct skewed, angled, bent, or warped card images before measuring. The Perspective Fix tool helps straighten card edges so you can get cleaner and more accurate centering measurements. --- Grade Comparisons --- Instantly see the best possible centering grades from PSA, BGS, CGC, SGC, TAG, and ACE as you adjust your card's ratios. Compare grading companies and see how each company's centering standards may affect your card. --- Front and Back Side Grading --- Measure centering for both the front and back of your card, since grading standards differ between sides. --- Pokémon e-Reader Card Mode --- Measure Expedition, Aquapolis, and Skyridge e-Reader cards correctly. The dot-code strip makes the left and bottom borders wider by design, so e-Reader mode compares the top and right borders the way graders do and saves the setting with each card. --- Grading Standards Reference --- View centering standards from PSA, BGS, CGC, SGC, TAG, and ACE in one convenient reference section. --- Cropping and Image Tools --- Crop card images, upload from your photo library, scan with the camera, or upload a card image from a URL. --- Compatible With All Cards --- Use Card Centering Calculator with TCG cards, sports cards, and other collectible cards, including Pokémon, One Piece, Yu-Gi-Oh!, Lorcana, Magic: The Gathering, baseball, basketball, football, and more. Why Centering Matters: Centering plays a major role in determining a card's grade from professional grading companies. Even if a card is otherwise in excellent condition, poor centering can reduce its grade and impact its value. Card Centering Calculator helps you measure centering ratios before submitting cards for grading, giving you more information when deciding which cards to grade, sell, trade, or keep raw. Note: Card Centering Calculator focuses on measuring centering ratios. Professional grading companies such as PSA, BGS, CGC, SGC, TAG, and ACE also evaluate other factors, including corners, edges, surface wear, scratches, dents, print quality, and overall condition. This app does not assess those additional grading criteria.
