Have you ever thought why there is so much fuss about interior trims? Although they are important decorative elements today, they still serve functional purposes. Just notice where we all install interior mouldings: around doors and windows, at the upper section of the wall, and at the lower part of the wall. We actually frame our ceiling and all other structural elements in the room (doors, openings, windows etc.).

So, why do we all pay attention to interior trims?

Since they hide the joints created between ceilings & walls, window frames & walls, floors & walls etc. they must be made of the right material and purchased at the right size. If not, you might deal with moisture issues, mold etc. If the size is not right, they won’t cover the gap created between surfaces.

Speaking of interior molding size…

…gives us one more reason for focusing on what we buy. Whether we like or not, interior trims play a decorative role too. That’s why there are so many window & door casing, baseboard, and crown molding profiles. Even if the seam between the window jamb and the wall is tiny, you might choose a large trim. The size is always associated with the size of the room and the height of the ceiling.

A slim window casing in a high and rather large room with very big windows will look poor and insignificant. You don’t want that. Interior trims are installed for functional reasons but must make a statement too.

What’s even most important with interior molding is the balance they bring in the room. Their size will either provide the right proportions to bring harmony or change the structural impact of the space in a negative way.

Think of the crown molding & baseboard combination

When you install crown molding and baseboards, pay attention to their size. Even if they are not identical, they must be similar. And their size must be proportional to the size of the room and the ceiling’s height. The larger the room and the taller the ceiling, the wider moldings should be. But the two of them must be a perfect pair in terms of size and style.

The best interior trim choices

  • The marriage between crown moulding and baseboard is the best ever. With or without wainscoting panels splitting the wall, these two trims make the perfect pair.
  • Another way to use interior trim is over the kitchen cabinets or bedroom closets. Sometimes, they go all the way to the ceiling. But if they don’t, they simply create what we call a “cabinet soffit”, which is unattractive and often dark. You can give some character to this dowdy space by installing a ceiling trim. If there is enough space, you can install cove crown molding along with cove lighting. Such solutions are also great over bookcases or bathroom cabinets.
  • Sometimes, a section of the wall is protruding. That’s where we often install picture rails. If you have a protruding wall, you can still install crown moulding to close the unattractive gap and create a soft transition from one part of the wall to the next.
  • Doors and openings are also trimmed – just like windows. A nice trim will frame them to give some character and create a visual interest to each entry point within the house.

Our advice for the best interior trim installation: don’t overdo it!

Too much trim will kill your interior design efforts! Remember what we said about slim trims in large rooms and about scale & proportion? That’s one way of looking at it. It takes balance when you make trim choices not only in terms of trim size but also how much trim you use in each room. If you trim the windows, columns, doors, openings, the ceiling, and the walls, you will end up with a stuffy room that won’t let the eye rest. And that’s not a good thing.

The eye must be able to find some naked spaces to rest and get attracted by the next trim in the row. You can install baseboards and ceiling molding. You can even install a shaker or beadboard in between. Or you can lose the wall panel and make door & window casing the focal points. If there is a ceiling medallion, you might want a similar crown molding design. But in this case, don’t install any more ornate trims in the room.

Remember: You need to keep a good balance in regard to the interior trims & ceiling height, the size of all interior trims in one room, and how you trim a room. If you pay attention to this trio, you will get a beautiful and friendly room, and so your efforts will be rewarded.
