A full size mattress, sometimes called a double size, measures a wonderfully simple 54 inches by 75 inches. That gives you four and a half feet of width and just over six feet of length. Sounds spacious enough, right? Well, here's the fun part — that 54-inch width is the exact same as someone's shoulder-to-shoulder plus a pillow each. So if you plan to share, you might end up locked in an accidental agreement sleep every night. No pressure!
This size is super versatile. It's perfect for solo adults who want real room to stretch out, teenagers upgrading from a twin, or couples living in cozy apartments where every inch counts (pun very much intended).
One thing to keep in mind: while we call it "full," it's actually not fully enough for two grown adults to sleep comfortably. It's like calling a minivan an SUV — technically not wrong, but let's manage expectations here. 😄 Those who mattress share at this size usually end up cuddling (or asking Santa for a bigger bed already).
