Trading Card Size & Trimming Check
Trading Card Size & Trimming Check
Pick your card type, enter its measured width and height, and this trimming check compares them to the known dimensions for that issue — an undersized card can be a sign of trimming. It covers every major issue from today's standard size back to 1880s tobacco. Everything runs in your browser; nothing is uploaded. For the full dimension chart of every set, see the Definitive Trading Card Size Guide. Measuring centering instead? Use the Card Centering Calculator.
Measure the card's outer width and height with a ruler or calipers, then enter them below.
A size match doesn't rule out alteration, and an undersized card isn't always trimmed (cards vary, and measuring error is common). Treat this as one signal alongside an edge, corner and surface inspection.
About this tool. Dimensions are cross-verified against PSA CardFacts and standard hobby references; a few issues with documented source disagreement are flagged in the size guide. The trimming check is an independent aid — not affiliated with, endorsed by, or operated by PSA, SGC, BGS/Beckett or any grading company — and it is not a price or value guide. An undersized measurement is one clue, not proof of trimming.
