Fit answers

Every page below runs the same default stress test: 100 cards, double-sleeved (a Dragon Shield Matte outer over a KMC Perfect Fit inner), checked against one specific deck box. It's close to the toughest common case, so a box that clears it clears almost anything lighter.

Across all 60 boxes we've run through it, 28 fit cleanly, 16 land Tight, and 16 don't fit at all. That last number looks worse than it is. Line the failures up against each box's own stated capacity and every one of them is a box rated for fewer than 100 cards to begin with, a 40+, a 60+, three different 80+ models, being tested against a stack it was never built to hold. Ask a box actually rated 100+ or larger the same question, in almost every brand, and the answer is Fits or Tight. Never No.

The one place brand genuinely changes the outcome rather than just capacity: Gamegenic's XL Convertible line, where a 100+ label doesn't guarantee comfortable room because the manufacturer's own number already assumes extra-thick inner sleeves. The brand notes below dig into that and the other patterns worth knowing before you buy.

If you just want a shortlist, start with the three ranked pages. Everything else is organized by brand with the verdict shown next to every link, so you can see at a glance whether your box actually clears 100 double-sleeved cards or how far short it lands.
