Stand at your door measure the room from your left to your right, that is the width of your room. Then measure from the door to the back wall that is the length of your room. Standard height is 8 feet, shouldn't be an issue with a bed unless you have bunk beds in an upper floor room with a funny roof angle or a converted attic.
So I'm getting a new bed for my room (obviously) And I wanted to measure my room to see if it would fit well, but I'm not sure which order the product dimensions go in... I'm getting it over summer so I need a fast answer, if you know please bother to answer, Thx!!
