Can a twin mattress fit through any door?

Virtually yes. A twin on its side is only 8–12" thick and 38" tall — this clears any standard door (24–36" wide, 80" tall). The only challenge is the 75" length in tight hallways.

What is the difference between twin and twin XL?

A twin is 38" × 75". A twin XL is 38" × 80" (5 inches longer). Both fit through standard doors equally well, but the XL may be slightly harder on tight staircase landings.

Can I fold a twin mattress to move it?

Foam twin mattresses can be folded in half or rolled without damage. Innerspring twins should not be folded but are light enough (40–50 lbs) to carry on their side through any doorway.
