Basic bunk beds - 3 bunks. Here are some design options for 3 bunk beds. If you have a 9ft (274cm) ceiling then you can fit 3 bunks in with the bottom bunk on the floor. Adults using these bunk beds would risk a few banged heads but they'd be fine for up to 9 year olds (based on average sitting height).
Twin sized mattresses are typically 38 to 39 inches in width. For headboard design, it's typical to add at least 6 inches to the width, making it 44 or 45 inches; the extra 3 inches on each side gives the mattress a bit of wiggle room to move. Headboard height is subjective, but typical height is about 24 inches above the top of the mattress. If your mattress is of typical height, the overall height of the headboard from the floor to the top should be at least 36 inches. Add another 6 to 12 inches to the height if desired for aesthetics.
