what height christmas tree should i buy

It depends on the size of the room and how many decorations you want to put on it. A six-foot tree is a good size for most rooms, but you could go as high as eight or ten feet if you have the space and want a grander statement. If you're going for a minimalist look, a four-foot tree might be sufficient. Just make sure you have enough ornaments and lights to fill it out nicely!
