Difference Between Cornice and Crown Moulding

If you are a stranger to all things building material, supplies, and tools, then the decision between choosing cornice or crown moulding may be a tad confusing and overwhelming. Especially when a quick Google search leaves you feeling like the words are essentially interchangeable. But while these two architectural details are often believed to be the same thing, here’s what makes them different!

They Are The Same, But Different

It’s true! They are both ornamental trim mouldings used to cover the juncture created when the wall end and a roof, balcony, or ceiling beings. But the difference between cornice and crown moulding is this:

  • Crown mouldings “crown” the surface of something – just like a crown would! You can install crown moulding almost anywhere, in any room. Not only does this add character, but also draws your eyes upwards. This lifts the space, making the structure feel taller and adding that special finishing touch. You can also use crown moulding to cap bookshelves, fireplaces, and cabinets. As such, crown moulding is more adaptive and diverse than cornice.

  • Cornices are essentially a type of crown moulding, but serve the purpose of directing rainwater away from the walls. Rather than only drawing up, they also project outwards. In this sense, crown moulding is strictly an indoor feature, while cornice is mainly found outside buildings. It is rare to use cornice for capping furniture or other interior details. So while cornice can also be designed in a variety of different ways, there is still only one type of cornice. On the other hand, there are many different types of crown moulding.

Whichever you choose, adding either of these options to your building will incorporate function and stunning detail. Both cornice and crown moulding range in styles; from intricately detailed classical looks to sleek modern minimalism. There is sure to be a trim that is right for your home or property.
