Spacing a door is tricky since you need to leave enough of a gap for the door to move freely and not get stuck when the slab and frame contract and expand in dry and humid conditions. The ideal gap between a doorframe and slab is 1/8 of an inch. If the gap is any larger, the door will feel drafty. But if the gap is any smaller, the slab can get stuck due to weather changes.

To build a standard size, six-panel door yourself, you’ll need four 2-foot by 6-foot boards, one 2-foot by 8-foot or 2-foot by 10-foot board, and a sheet of 3/4-inch, paint-grade plywood. The 2-foot by 6-foot boards will serve as your stiles, top rail, and horizontal and vertical mullions, and the wider board will serve as the bottom rail, which is usually wider than the other horizontal pieces. The plywood will serve as the panels, but you’ll need around five 1-foot by 6-foot boards to make your own panels if you want to stain the door rather than paint it.

The best material for a patio door depends on several factors, including your budget, local climate, and priorities like style, security, and maintenance. Wood offers a classic, high-end look but requires regular upkeep. Vinyl is a popular choice as it's affordable, energy-efficient, and low-maintenance, making it a durable option for active households. Fiberglass is another durable material that stands up well to heavy use. For superior security, steel is a low-maintenance option, though with fewer design choices. Finally, lightweight aluminum makes doors easy to open and close, which is ideal for homes with children. The right choice balances durability, aesthetics, ease of use, and the amount of maintenance you're willing to perform.

You can use wood, metal, or plastic as a door shim, but keep in mind that wood will rot easier than the other two materials. Your local hardware store should have at least one type in stock. Alternatively, you can trim a piece of cardboard to fit underneath your door hinge and work as a temporary, makeshift door shim.
