GAOMON King Size Bed Frame with Headboard: Frame vs. Mattress
80.9″ × 76″ frame, 39.4″ tall (as published - includes the headboard if this bed has one), per the manufacturer. Fits, tight (W +0″ / L +0.9″ vs. standard)
This checks each frame's own published length and width against a standard mattress of the size it's sold for - Twin, Queen or King - using the industry-standard US mattress dimensions, not a figure GAOMON publishes. It is not a check against your room; see the worked example below for that. "Height" is each frame's single published figure, which includes the headboard where one exists - proven by the one headboard-less frame in this range (a 6 in low-profile Queen), whose own published height is exactly its frame height with nothing else added.
