At RealCraft, we also help advise our customers on choosing a door and the right hardware. To select the perfect barn door, start by measuring your doorway to determine what size barn door you’ll need. We recommend that the door overlaps the opening by at least one inch all the way around. Next, select your barn door style and wood species. Then choose the finish you prefer and, finally, determine whether you’d like your barn door finished and assembled by our team or if you’d like to finish and assemble it yourself. RealCraft Sliding Barn Doors are easy to assemble and include all the parts you will need.
