Sleeves, boxes and binders calculator for your collection
A BCW “800” box holds about 1,140 unsleeved game cards, a single-row “1000” box about 550 sleeved ones, and a Zipster Regular binder 360 single-sleeved or 324 double-sleeved cards. Enter how many cards you have and how you sleeve them to see how many boxes, binders and sleeve packs you need.
Where the capacities come from
Each figure is the one printed on the manufacturer’s product page, as collected in our sleeves and organizing guides: BCW for boxes, Dragon Shield for Zipster binders and Ultra Pro for 9-pocket binders. For a box of any other brand, the rule from those pages is about 31 unsleeved or 17 sleeved cards per centimetre of inner length.
Box names are not capacities: the “800” box is named for thinner sports cards. Leave some room in every box, as a packed box bends the cards at the ends.
