Also be sure to measure the bed frame, if you already have one. This will also need to fit within the headboard. The general rule when measuring the height of the headboard is this: measure half way up the wall of the room where the headboard will be placed against. Your headboard should never exceed this height! Try to find a headboard that either reaches half way or down to a few inches below that point. This will prevent the headboard from "crowding" and overpowering the room.
Create a nautical decor - deep blue and white which are reminiscent of the seas make for an inspiring nautical decor combination for the master bedroom. Use this colour combination for the linen, the furnishings, the upholstery and even for the wallpaper. An inspired idea would be to use the combination in stripes for the ceiling instead of in the wallpaper.
