The fit guide

Will yours fit? Here's the whole answer.

One spec, one desk-drawer test, and the exact measurements for the cups and cans people actually bring. Every number below is sourced — nothing is guessed.

Container bases 2 to 3 inches across settle in fully. The flexible fins accept slightly wider bases up to 3.15 inches — a snug fit that seats with a push. Under 2 inches sits too loose; over 3.15 doesn't seat.

The 10-second version

Skip the calipers — the sticky note already has the answer.

your cup's base
lands in here
  1. Grab a sticky note. The classic square is exactly 3 inches on a side — a fact about sticky notes, and it happens to land right at the ceiling of what fits.
  2. Stand your cup on it before you pick the chisel back up. Set it on the note, not balanced on the rim. A tapered tumbler or a flared cup lies about its true size — the bottom is the only measurement that counts.
  3. Read the note. Base sits inside the square? It fits. Hangs over the edge? Too wide. A tiny puck lost in the middle — under 2 inches? Too narrow.

No calipers, no spec sheet, no guessing at the store. One sticky note off the pad, one glance, with the cup you actually bring out to the shop.

The handle rule

Classic handled coffee mugs don't fit at any base size — the handle sits exactly where a fin needs to grip. Handle-less mugs and camp cups inside the range are fine. (Tall tumblers with high handles, like the Stanley Quencher, are fine too — their handles sit far above the fins.) Espresso cups sit under the 2-inch floor: too loose.

Where these numbers come from

One rule covers the whole shop: a container base 2 to 3 inches across settles in. Every verdict below follows from it.
