Architectural Elements
Crown Molding
Crown molding is decorative trim installed at the junction of walls and ceilings, softening the transition between these surfaces while adding architectural refinement. Dating back to ancient Greek and Roman architecture, crown molding has remained a hallmark of quality interior finishing for millennia.
The visual impact of crown molding comes from its profile—the specific combination of curves, angles, and flat sections that catch light and create shadow lines. Profiles range from simple coves to elaborate, multi-piece assemblies. Properly installed crown molding makes ceilings appear higher and rooms more polished.

Works Well With These Styles
Placement & Usage Tips
Standard rooms (8-9 foot ceilings) suit 4-6 inch crown. Taller ceilings can handle larger profiles. Paint crown the same color as ceiling to emphasize height, or match walls to highlight the detail.
💡 Pro Tip
Crown molding installation requires precise angle cuts—inside and outside corners are tricky. If DIYing, consider using corner blocks that eliminate complex miter cuts, or lightweight foam crown that cuts with a miter box.
