Quick Answer

To choose the right card holder size, match the holder's point (pt) thickness to your card's exact thickness—most standard TCG cards fit a 35pt holder, but thicker cards or those with sleeves may need a larger size.

Why Size Matters for Card Protection

Using the wrong holder size can leave your cards loose (risking scratches) or force them in too tightly (bending edges). A properly sized magnetic holder like the Ultra PRO One-Touch Edge secures the card without pressure, preserving its condition for display or storage.

35pt vs. Other Sizes: What's the Difference?

The 'pt' measurement refers to the interior depth of the holder in points (1 pt = 0.001 inch). A 35pt holder fits standard unsleeved trading cards like Magic: The Gathering, Pokémon, and Lorcana. Thicker cards—such as those with toploaders, multiple layers, or special foil finishes—may require 55pt, 75pt, or even 100pt holders.

Step-by-Step Guide to Choosing the Right Size

  1. Measure Your Card's Thickness: Use a caliper or a thickness gauge to measure your card in millimeters. Standard TCG cards (like Magic: The Gathering) are about 0.36mm thick, fitting a 35pt (0.89mm) holder. For sleeved cards, add the sleeve thickness (usually 0.1-0.2mm). Common mistake: Assuming all cards are the same thickness—foil or etched cards can be slightly thicker.
  2. Check the Holder's Point Rating: Look at the product description for the point (pt) size. A 35pt holder works for most unsleeved cards. If you plan to use a sleeve, choose a 55pt or larger holder to avoid compression. Checkpoint: Verify that the holder's pt rating is slightly larger than your card's measured thickness.
  3. Test the Fit Before Committing: Place the card gently into the holder. It should slide in without force and lie flat. Close the magnetic lid; if the card shifts or the lid doesn't close flush, the size is wrong. Common mistake: Forcing a card into a tight holder can bend corners or damage the surface.
