Most BCW cardboard boxes are only large enough to hold standard 2½ x 3½–inch cards or cards in sleeves. However, several boxes have wider rows to accommodate cards in protective holders such as semi-rigids, toploaders, one-screws, magnetics, or other holders or cases. Other BCW boxes are designed to hold graded cards or tall cards. A few boxes have both wide rows and increased height.

If you are trying to decide which BCW boxes are right for your collection, the list below shows the sizes. If you store cards in protective holders, you’ll need a box with WIDE rows. If you have graded cards, other tall cards, or you have four-screw card holders, get a box labeled GRADED.
