I have a king mattress and ordered the king headboard. The headboard doesnt align with the bedrails, its a bit short to utilize the the screws for each side. We were still able to use by pushing the bed into the legs against the wall. Not ideal but it worked and saved hassle of returning. Measured before ordering so I am not sure why this happened. The color is darker and dustier just as stated in other reviews. Very pretty but will limit color choices of future bedding.
