Guides
Each guide answers one fit or storage question, using the numbers manufacturers publish. Where they publish nothing, we say so.
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.
Storage
Card storage boxes by capacity, and what each one holds
The number on the box assumes a certain card. Here's what each count actually means, and which boxes take top loaders.
Graded slabs
Graded card storage and display, by grading company
Slabs differ by grading company, so a slab product is only an exact fit for the companies its maker names.
