What to measure before ordering
- Identify what you are replacing.
A slab is the door panel. A prehung unit includes a frame. Record whether you need a slab or a complete unit, and check exactly what the selected product includes.
- Measure the opening and the frame.
Record the width and height in several places, plus the wall or jamb depth. Keep rough-opening measurements separate from the existing door's dimensions. Include the units with every measurement.
- Confirm the swing and the exact model.
Note which side the hinges sit on, the side you are viewing from, and whether the door swings toward or away from you. Confirm handing terminology and required clearances against the manufacturer's documentation for the selected SKU.
These notes are a planning aid. Product names, photos and shared descriptions do not confirm fit. Check the selected SKU, manufacturer specifications and installer measurements before ordering.

Sunlit Craftsmanship in Natural Knotty Alder
This barn door infuses interiors with a relaxed, curated sophistication—the knotty alder’s organic grain pairs beautifully with the crisp geometry of four glass lites. I love the way the clear panes visually expand a room, creating a luminous passage that feels airy and intentional. Stain it in a warm honey or deep espresso and style with matte black hardware for a tailored contrast. It’s a chic essential that elevates everyday living with artisanal warmth.
