What size top loader do I need?

The short answer

For a standard 2.5” × 3.5” card up to 35pt, a standard 3” × 4” top loader is the size both Ultra PRO and Vault X rate for it. For anything thicker, measure the card and buy the smallest rating at or above your measurement.

Sizes the makers publish

Vault X publishes the same 70 × 98 mm inside size for every rating; the rating changes the depth. Ultra PRO publishes the 3” × 4” outside size and the card size (2-1/2” × 3-1/2”).

Why the smallest size that fits

A rating is the thickest card the holder takes. A 35pt card in a 130pt top loader is inside the rating, but has 95pt of spare depth and can slide around. The Fit Finder calls that “fits, with room”. The smallest rating at or above your card is the snug fit, which is what the makers’ size ladders are for.

When to re-measure

If your card is within about 5pt of a rating, measure again. Ratings describe the card itself. A soft sleeve adds film that the rating does not count, and makers don’t express sleeve film in points.

Above 130pt

Top loaders in our catalog stop at 130pt. For thicker cards, magnetic holders go higher: Ultra PRO publishes ONE-TOUCH sizes up to 360pt. See magnetic card holder sizes.
