How much cornice do I need, and what size should I get?
Our cornices are all produced and distributed in 2.4m lengths. For ease of use, we have added the below table to calculate how many lengths you would require. We would recommend adding 10% to account for cutting etc.
You can calculate the meterage required by adding the length of each wall of your room. Example: A 4m x 6m room would require 20m of cornice (4 + 4 + 6 + 6).
| Meters to be covered | Lengths (including 10% overage) |

How much adhesive do I need?
You would also need to estimate the amount of adhesive required to install cornice.
Generally, the medium (60mm – 80mm) cornice would require 2 300g tubes of adhesive per 10m, and larger profiles (80mm – 100mm) might require up to 3.
How cornice is measured, and choosing your size
Cornice dimensions are generally based on the measurement of the cornice coverage down the wall (drop) and along the ceiling (projection).
When we refer to a 100mm cornice (or 100 x 100mm) it would be a profile that would measure 100mm down the wall and 100mm along the ceiling once installed.
Below is an illustration of this using the profile of our popular Brighton cornice.

Most of our range will be available as 80mm or 100mm variants, however we have the ability to customise to other popular sizes, including 75mm, 130mm, 150mm etc.
As a rough guide, we would recommend an 60 – 80mm profile for ceiling heights from 2.4m to 2.7m and 100mm for 2.7m to 3m. When you get to 3m and over, you would be looking at 130mm and upward.
