Start with the sleeve, then the holder

Select the sleeve class intended for your game. For thick cards, use a maker thickness gauge; choose the smallest published holder capacity at least as large as the measured thickness. Do not force a snug fit.

Worked example

A standard card needs a standard sleeve. A 35 pt card needs a holder rated for at least 35 pt. One point is 0.0254 mm, so 35 pt is 0.889 mm. Sleeve space and holder design still matter: check the maker’s compatibility guidance.
