“L” = Length/span
“H” = max Height/Drop (i.e. down the wall from the ceiling) in cm
“P” = max Projection (i.e. the measurement across the ceiling from the wall) in cm
Quite frankly it is pretty much the same thing. But whilst not an absolute rule, coving is the term that is often applied to a ceiling moulding that is generally uniform in profile, projecting across the ceiling roughly the same distance as the drop down the wall (so it could be 10cm x 10cm for example). Generally speaking, it is simpler in design and is typically (though not always) formed around the traditional quarter-circle ‘C’ profile.
Coving profiles tend to come in different sizes, the most common of which is the 5” (127mm) cove. This measurement often causes confusion – it refers to a straight line drawn across the diagonal from wall to ceiling (not the height or projection of the coving, which – for the 127mm cove – is actually 80mm x 80mm).
Most house builders in the post-war period installed this plain cove because it was simple and effective – and very cheap to make. It is still probably the most common coving in Britain.
Cornice on the other hand often tends to be more ornate and is less uniform dimensionally (though it could potentially still have the same projection and drop). So a piece could be 150mm across the ceiling but only 100mm down the wall (or vice versa). The shape of a cornice can also be very complex indeed, with different curves and flats. There have been numerous designs and patterns reflecting the changing architectural fashions of the time.

Traditional plaster decorative coving and cornice
Plaster (often using lime and hessian backing) is traditionally the manufacturing material. However, the inherent problem with plaster is that it is both extremely heavy and fragile. Problems would occur when hanging this weight from the ceiling. Any subsequent movement in the wall or ceiling often meant unsightly cracks would appear, and – at worse – sections falling off. The 1970’s ‘solution’ was polystyrene which, whilst cheap and easy to install, was visually inferior and proved unpopular.
Modern coving materials
Technology has improved dramatically since then and the industry standard material is now hardened polyurethane. This has the visual beauty of plaster coving but without the inherent disadvantages. It is best described as being like ‘light wood’. A nice clean and sharp edge is achieved by cutting with a standard medium tooth crosscut saw or alternatively an electric mitre or ‘chop’ saw.
Installation benefits of hardened polyurethane/duropolymer mouldings
The lightweight nature of this material means that adhesive is all that is required in order to fit to the wall – no screws are necessary. An undercoat/primer is also already applied so it is ready to be painted with a final finish coat. And the final look? The same as plaster cornice but without any anguish or frustration.
