Card Protection Fit Finder
Tell us what you're protecting. We check it against the size and thickness ratings each maker publishes for 60 products and sort every one into exact fit, fits with room, unverified, or won't fit.
Results
The maker rates or names it for your setup, and it's the snug size.
Inside the maker's rating, but looser. Your card may shift.
The maker doesn't publish enough to say. We won't guess.
The maker's numbers or stated exclusions rule it out.
How the Finder decides
Every rule uses a published number or statement from the product's maker: a thickness rating ("up to 75pt"), an internal size, a named grading company, or an exclusion such as "designed for unsleeved cards". The rules are fixed code, the same answer every time, with no AI in the loop. Specs were last checked October 15, 2026. The full rule list is in our methodology.
Thickness ratings describe the card, not the card plus a sleeve. When your card is within 5pt of a rating limit we tell you to re-measure.
