The classical order
/Proportions matter! Choosing the proper moldings for your project can make the difference between a project that feels right or one where “something’s not quite right.” While they’re open to interpretation, there are rules regarding how we use mouldings, which profiles we choose, what sizes of each, and the layers that we use to build them up. There are about a dozen different interpretations of the classical order from architecture texts over the last couple of centuries, but a few things stand out as constants.
There are a few books that I would recommend if you’re interested in moulding design and proportions. I’ll update the article as time allows to expand this list, but I would start with C. Howard Walker’s The Theory of Mouldings (Linked for your convenience)
To hit the high points on moulding profiles and proportions quickly, there are a few rules
The higher the ceilings, the larger the mouldings (and their projections)
Don’t repeat mouldings! Motifs, but never the same moulding in the same proportion.
The types of mouldings, their placement, and proportion to one another are derived from the classical order which was rooted in a moulding’s structural nature!
Columns taper at the top
Crown mouldings were originally structural to distribute the weight of the beams above
Profiled edges weren’t just ornamental; they actually reduced wear and increased longevity
Fluting and reeding are actually derived from bundled reeds that served as pillars in early structures
Eaves, sills, gable roofs, they all are intended to direct water away from the structure’s foundation
When you start looking for mouldings that are out of proportion, you’ll see them everywhere! But, rest assured, we don’t lead you astray. A that’s why we’ll never recommend a 12” crown moulding for your 8’ ceilings.
