You may have some idea of the Cornice you want for a room already, however its not always straight forward, many houses have had all of the Cornices removed possibly to ceiling damage and the owner may not have had the budget to reinstate them leaving no guidance for the new owner.
You could research the build date of your house online, once you have an idea you can use our Cornice period categories, however there can be some overlap in period styles which don't conform to the period datings as trends changed gradually. So for the best guidance we advise if possible asking a neighbour if you could view their Cornices,
The height of your ceiling and the room size
dictates the size of the Cornice required, to help with this all of our stock Cornices have this guide on there page to help you choose correctly.
PLAIN OR ENRICHED
We feel this is a question of personal taste, you also don't have to use an enriched Cornice because there was one there before and vice versa as long as the Period is correct. Another point worth making is that enriched Corniecs are generally more expensive to supply & install than plain Cornices.
