Shutters are still very common in Southern, farmhouse, and traditional-style homes, especially those in warm climates who can benefit from the increased efficiency. While modern homes and designs tend to shy away from shutters, shutters are a timeless design style that will likely be around for decades to come. 

Not all windows are suitable for shutters, as certain styles can prevent them from functioning correctly. It's best to avoid installing shutters on bay windows, picture windows, dormer windows, and double-mulled windows. Shutters are better suited for large, full-size standard windows or French doors.

Additionally, consider the room's lighting needs. Since shutters effectively block light, they are an excellent choice for rooms where you want more darkness and privacy, such as a master bedroom or a main living room. For window types that are not ideal for functional shutters, some homeowners choose to install fixed (non-functional) shutters to maintain a consistent look across the home.

Wood is the most classic shutter material. Common options include pine, cedar, or brasswood. MDF shutters are also a more affordable option that retains the timeless, classic look. Composite shutters, mainly vinyl and aluminum shutters, have also become more popular over the years. You may also find steel shutters, sometimes referred to as security shutters, used on the exterior. Shutters also come in various colors and finishes, adding another layer of design flexibility.
