Trading card protection, measured

Know what fits before you buy.

Which top loader takes a 75pt patch card? Will a magnetic holder take a sleeved card? Does your binder fit top loaders? We answer from the sizes and ratings manufacturers publish, and we say plainly when they don't.

How fit works

  1. Measure in points

    Card thickness is sold in points: 1pt is 0.001". A base card is often around 20pt; relics and patches run much thicker.

  2. Match the rating

    Holders are rated by the thickest card they take. The smallest rating at or above your card is the snug fit.

  3. Check the whole stack

    Sleeve, then holder, then binder or box. Each layer has its own published limits, and the Finder checks all of them.

Guides

Answers to the fit questions collectors ask

All guides

Rigid protection

What size top loader do I need?

Measure the card, then buy the smallest rating at or above it. Here is how the published sizes line up.

Rigid protection

Magnetic card holder sizes, 25pt to 360pt

Magnetic holders are sold by point rating like top loaders, but the sleeve rules differ by brand.

Binders and pages

Binders that fit top loaders

A regular binder pocket is sized for a sleeved card, not a 3" × 4" top loader. These binders are built for the top loader.

Sleeves

Penny sleeves vs perfect-fit sleeves, and when to double-sleeve

Penny sleeves are the everyday first layer. Perfect-fit sleeves are inner sleeves for double-sleeving. They solve different problems.

Basics

How to measure card thickness in points

Every holder size is a point rating. Here is what a point is and how to measure your card without guessing.

Storage

How to store trading cards long term

Long-term storage is three decisions. What touches the card, what keeps it flat, and what keeps the stack dry and dark.
