Coving vs Cornice – What’s the Difference?

If you’ve been looking at ways to finish the junction between your walls and ceilings, you’ve probably come across two common terms: coving and cornice. At first glance, they seem to mean the same thing — and in everyday use, people often use them interchangeably. But in plastering and interior design, there is a subtle difference between the two.

In this guide, I’ll explain exactly what sets plaster coving apart from plaster cornice, share a little history, and help you decide which might be the right choice for your home.

What is plaster cornice?

Cornice is a broader term that refers to more decorative mouldings at the junction of wall and ceiling. Historically, in classical architecture, the cornice was the projecting moulding that crowned a building.

Inside the home, plaster cornice tends to include much more detail than plain coving. It might feature patterns such as leaves, flowers, rope twists, dentils, or the well-known egg-and-dart design. Cornice mouldings often project further from the wall and ceiling, making them stand out as a statement feature.

You’ll often see plaster cornice in:

• Period homes such as Georgian, Victorian, or Edwardian properties

• Rooms with high ceilings, where ornate details feel proportionate

• Homes where the owner wants to add traditional character and elegance

Key differences between coving and cornice

Although the terms are close, here’s a simple breakdown:

• Shape: Coving tends to be curved and simple, while cornice often has complex, angular, or patterned profiles.

• Decoration: Coving is plain and symmetrical; cornice is decorative and detailed.

• Impact: Coving softens a room, cornice makes a statement.

• Suitability: Coving fits modern homes, cornice suits period properties.

Think of coving as the understated option and cornice as the ornate one.

Why choose plaster instead of alternatives?

Both coving and cornice are available in different materials — plaster, polyurethane, and polystyrene among them. However, plaster has several advantages:

• Authenticity: Nothing matches the crisp detail of traditional plaster mouldings.

• Durability: Plaster is strong and long-lasting compared to lightweight alternatives.

• Repairable: Damaged plaster mouldings can often be repaired seamlessly.

• Period-correct: In listed or heritage properties, plaster is the only appropriate choice.

If you want the finish to look high quality and last for decades, plaster remains the gold standard.

How to decide which is right for your home

When choosing between coving and cornice, consider:

• Style of your property – Is it a modern build or a period home?

• Ceiling height – Decorative cornice works best in rooms with higher ceilings.

• Your taste – Do you prefer understated elegance or detailed ornament?

• Budget – Plain coving is often more cost-effective than intricate cornice.
