Frequently Asked Questions

Any standard 63×88mm trading card — Pokémon TCG (modern and vintage), Magic: The Gathering, Yu-Gi-Oh!, sports cards, One Piece, Lorcana, and more. If it's a standard-size card, it works.

No — and it's not trying to. This is a pre-check tool. Use it to decide which cards in your collection are worth the cost of sending to PSA / BGS / CGC / TAG. The actual grade is decided by their graders.

Within ~1mm when you align the boxes by hand, and our trained ML model now lands auto-detection close enough that most cards don't need any nudging in either mode. That's the same precision PSA centering tolerances are scored at, so it's sufficient to tell a 50/50 from a 60/40 from a 70/30 reliably.

Yes. Bulk upload is built in — drop a folder of card photos and we'll measure each one in sequence and let you save the keepers to your collection. Built for resellers and store owners pre-grading inventory.

Only if you click Save to add the card to your collection. Otherwise images are processed in-memory and discarded after the analysis returns.

2 free analyses on signup. After that it's a flat subscription — weekly or semi-annual — for unlimited measurements across web and mobile. No per-card credits, no mode-specific pricing. Cancel anytime.

You've got options. Midpoint - Card Centering Tool runs entirely in your browser on desktop or mobile — no install, no plug-ins. Or download the free native app for iPhone (App Store) and Android (Google Play) for a camera-first experience. Your account and saved cards sync across web, iOS, and Android.

Centering ratio (L/R and T/B), exact mm offsets per edge, predicted grades from PSA / BGS / CGC / TAG, a full surface analysis covering edges, corners, print alignment, and holo/foil condition, and the auto-detected card name. Every analysis runs the same pipeline — there is no separate AI/Basic mode anymore.

Yes. Every card you save that has been identified gets a market value, and the Portfolio tab shows the total collection value with a value-weighted 30-day change, refreshed automatically every day from eBay sold-listing data. It goes well beyond a number: record what you paid to see gain/loss per card, mark cards sold to build a realized profit/loss ledger, file cards into binders, track grading submissions, set price alerts, export to CSV, and display values in your own currency. All of it syncs between the mobile app and the web.

Yes. Every saved card can carry a cost basis (what you paid), and when you sell one you mark it sold at the sale price — it moves out of your live portfolio into a realized profit/loss ledger. The Portfolio tab shows your holdings' current value, today's change, gain/loss against what you paid, and your all-time realized P&L from sales. You can also organize cards into binders, track cards you've sent to graders (with fees, so the ROI math stays honest), export everything to CSV, and view values in your own currency. It works the same on the mobile app and the web.

A card centering tool helps collectors and sellers measure the border alignment on trading cards to assess how centered the card design is. Proper centering is important for card grading, as grading services like PSA and BGS evaluate centering as part of a card's overall grade. Tools can be physical templates, rulers, or digital apps like Midpoint, which analyze images to provide centering measurements and ratios.

A card centering checker provides measurements or visual guides to assess whether a card's printed image is evenly positioned within its borders. This helps collectors estimate the potential grade a card might receive. Tools like Midpoint automate this process using digital image analysis for fast and accurate results.

Card grading apps assist users in pre-screening their trading cards before submitting them to professional grading services. These apps can analyze centering, check corners, and sometimes estimate overall grades. Midpoint focuses specifically on centering analysis, giving collectors actionable data for grading decisions.

Sports card centering tools help collectors evaluate how evenly the printed image is positioned within the card's borders. This is important for grading, as poor centering can lower a card's value. Tools like Midpoint provide automated, accurate centering measurements for sports cards using uploaded images.

PSA centering tools help collectors assess whether their cards meet the centering requirements for a given PSA grade. These tools provide centering ratios or percentages, allowing users to pre-screen cards before submission. Midpoint can calculate centering based on PSA's grading guidelines.

Card centering calculators take input measurements of a card's borders and output a centering ratio or percentage. Digital calculators like Midpoint automate this process by analyzing a photo of the card, making it easier and more accurate than manual measurement.

Edge centering tools help collectors evaluate whether the card's artwork is evenly positioned within the card's physical borders. This is crucial for grading, as uneven centering can reduce a card's grade. Tools like Midpoint analyze these distances to provide centering ratios.

Card centering tools work by detecting the borders of a card and comparing the size of the margins on each side. Digital tools like Midpoint allow users to upload a card image, then automatically analyze the image to provide left-right and top-bottom centering ratios. This helps predict how a grading service might evaluate the card's centering.

When you scan a card, Midpoint identifies exactly which card it is (name, set, and collector number) and attaches live market values sourced from real eBay sold listings. You see the raw (ungraded) price by condition plus PSA-graded prices by grade, 30-day trends, 6-month price-history charts, and recent actual sales with links to the listings. Prices refresh daily. Pokémon cards are covered today, with more games coming.

Yes. Lookup is built for exactly this: snap a photo of any card (or upload one on the web) and Midpoint identifies the exact card — name, set, and collector number — and takes you straight to its price page with raw and graded market values, price history, and recent eBay sales. If the photo could match a few different printings, you pick from a short list. You get 2 free lookups, and a subscription makes them unlimited. It's the fastest way to price a binder, a garage-sale find, or a card shop showcase.

Yes. Point the camera at a graded slab and Midpoint reads the label automatically — the grading company (PSA, BGS, CGC, or TAG) and the grade. The price page then highlights the value at that exact grade on the ladder, so a PSA 9 owner sees the PSA 9 price front and center, next to raw and PSA 10 values. That makes it easy to check what a slab is worth before buying or selling, without typing cert numbers into anything.

The best card centering tool offers precise results and a user-friendly experience. Digital apps like Midpoint stand out because they automate the measurement process using image analysis, saving time and reducing human error. Features to look for include support for different card types, clear centering ratios, and compatibility with grading standards.

Accuracy depends on image quality and correct alignment, but digital tools like Midpoint use advanced image analysis to minimize human error. For best results, ensure the card is photographed in good lighting and is not tilted or skewed. These tools are generally more precise than manual methods.

PSA evaluates centering using both visual inspection and precise measurement tools to ensure accuracy in grading. Collectors can use centering tools like Midpoint to pre-screen cards before submission, aligning with PSA's standards for centering.

Most centering tools, including Midpoint, support various trading card types such as sports and Pokémon cards. Accuracy depends on clear, unobstructed images and standard card layouts. Some irregular or heavily designed cards may be more challenging to analyze automatically.

• Physical tools: Place the card in a template or measure borders with a ruler.
• Digital tools: Upload a card image to the app, which analyzes and displays centering ratios.
• Review the results to determine if the card meets grading standards for centering.
• Midpoint lets you upload an image and instantly get centering feedback.

• Measure the left and right (or top and bottom) borders of the card.
• Divide the smaller width by the larger width.
• Multiply by 100 to get the centering percentage.
• Digital tools like Midpoint automate this process from a photo.

Many online centering tools, including Midpoint, are accessible via mobile browsers, allowing you to upload card photos directly from your smartphone. This makes it convenient to assess centering anywhere, without needing special equipment.

• Take a clear, straight photo of your card.
• Visit an online centering tool like Midpoint.

Pokémon card collectors often check centering by measuring the borders with a ruler or template, or by uploading a photo to a digital tool like Midpoint. The tool calculates the centering ratio, helping predict if the card meets grading standards for centering.

Centering is a key factor in trading card grading, and using a centering tool helps collectors estimate whether a card will meet centering criteria for higher grades. Tools like Midpoint provide fast, accurate centering measurements so you can decide which cards to send for grading.

While centering tools like Midpoint provide precise centering ratios, professional grading services also evaluate corners, edges, and surface condition. Use centering tools for the centering aspect, but remember that a full grade depends on additional card attributes.

Centering tools are designed to work with standard-sized trading cards such as baseball, basketball, Pokémon, Magic: The Gathering, and other collectibles. Ensure the card is clearly visible in the image for best results. Midpoint supports a wide range of card types.

Yes. Midpoint combines your card's centering-based grade estimate with real market prices to give a grading-ROI verdict: it highlights your estimated grade on the value ladder (raw vs PSA 9 vs PSA 10) and tells you whether the value jump covers the $25–50 grading fee. Instead of guessing, you see the actual dollar gap between selling raw and grading first.

Online card centering tools are web-based platforms where you can upload images of your trading cards for automated centering analysis. Midpoint is one such tool, providing quick and accurate centering feedback to help collectors make grading decisions.

While some basic centering tools or templates might be free, most accurate digital centering tools charge a fee for their services. Midpoint operates on a paid basis, so you may need to subscribe or pay per use to access advanced analysis and features.

Yes. On any card's price page you can set your line — a target price above or below the current market — and Midpoint watches it for you. When the market value crosses your threshold you get an email and (on mobile) a push notification. Alerts work on raw and graded values, and you control notification preferences in Settings, so you decide what lands in your inbox. It's how collectors catch dips before buying and spikes before selling, without checking prices every day.
