FYI: "Tournament-legal cards have a width x height measurement of 2.5x3.5, or 63.588.9mm. When it comes to the thickness, non-foil cards are about 0.012, or 0.305mm, thick. Foil cards, on their end, are a bit thicker as they have an extra layer on top of the card that creates that shiny, holographic look. When it comes to the corners of Magic cards, theyre rounded at a radius of about 0.125, or 3mm."
