Trim & Crown Moulding Styles
September 18, 2022

In the world of trim, crown moulding is a cut above the other mouldings and trims of the carpentry world. Even compared to door casings, chair rails, and baseboards, it cuts an impressive profile with pleasing curves and sophisticated angles. It also elevates a room's stature, pulling the eye upwards to the ceiling and echoing design motifs seen in other mouldings to create a cohesive and polished look for the space.
Crown moulding has been used as far back as the ancient Greeks, who created the profiles and the standards of proportion that we still use some 2,500 years later. The preferred material has for a much more malleable and relatively lighter-weight plaster or wood, rather than the original heavy stone. Wood and plaster are still the top choices for most traditional craftsman, homeowners can now choose moldings made from foam and flexible polyurethane, which are installed with greater ease than the Greeks, or even our grandfathers could have ever imagined—no chisel, trowel, or nails required.
At its essence, crown consists of an elongated S profile atop a cove. Adding trim beneath the cove, as shown, creates a cornice, though the entire assemblage is often referred to as crown.

What Size Should It Be?
​Keep these rules of thumb in mind when selecting crown for your house.
Consider the room's purpose. Traditionally, crown was incorporated into impressive cornices in public rooms, such as entry foyers, dining rooms, and parlors. The size would remain consistent from one first-floor entertaining space to the next. By contrast, smaller, less elaborate crown was generally used for private spaces—a powder room or bedroom.
Play off the existing trim. Look to your baseboards and door and window casing to determine the right scale. An appropriately sized cornice is either the same height as, or slightly smaller than, the baseboard.
Measure the ceiling height. Ceiling height is the ultimate arbiter of size, according to architect Richard Sammons, coauthor of Get Your House Right. For standard 8-foot-high ceilings, the crown/cornice height should be 2½ to 6 inches; for 9-foot ceilings, 3 to 7½ inches, and for 10-foot ceilings, 3½ to 8 inches.
What Style Should I get?
Keep these rules of thumb in mind when selecting crown for your house.
Consider your existing decor and consider your own personality. If you are someone who likes really flashy decoratoins than you might want to get more exotic trim work.

If the res of the house is really plain, you might run the risk of over-doing it with the trim. But you can always upgrade the rest of your house to match.
