Roomy means having plenty of space inside, with room to move around comfortably. A roomy car has enough space for passengers to stretch their legs without bumping knees. A roomy backpack can hold all your books, lunch, and gym clothes without being stuffed full.

The word emphasizes comfortable spaciousness rather than just size. A huge empty warehouse is big, but a roomy bedroom feels pleasant because it has space for your bed, desk, and toys while still leaving room to play. When someone says their new jacket is roomy, they mean it fits with extra space, not tight against their body.

You'll often hear roomy describe clothes, vehicles, houses, and containers. A roomy tent gives campers space to stand up and move around, while a cramped tent forces everyone to stay hunched over. The opposite of roomy is cramped or tight: when five people squeeze into a car meant for four, nobody would call it roomy.
