DIY Interior Trim Project

Looking for a great weekend DIY project that will add value to your home? Consider installing wood trim in your new home next weekend. Here are some great general tips and guidelines to follow for your next DIY weekend trim project.


  • Tape measure
  • Utility Knife
  • Hammer
  • Miter Saw
  • Miter Box
  • Black Plane
  • Nail Set
  • Stud Finder (Recommended)

Common trim types include:

Crown molding, installed at the ceiling and chair rail installed at the height a chair would hit it (preventing wall scuffs). Judges paneling is also very popular.  Trim is often painted with an interior semi-gloss finish paint

Step 1:

Start by measuring the perimeter of the room. This will come in handy when you are determining how much material you will need.

Step 2:

Next choose the type of trim you want and purchase the material. NOTE: Buy more trim than your measurements call for. This will allow for scrap ends plus any errors in measurement and any errors when cutting.

Step 3:

Next, start by measuring and cutting trim to reach from corner to corner. If you need to use more than one piece of trim to complete the full length of the wall, make sure to cut each piece of trim about 1/16 inch longer than your measurement. The trim might bow a little when you put it into position but this will create a tighter joint between the two pieces of trim when you nail it into place. Use as many nails as needed to close any gaps between the trim and the wall. NOTE: Make sure to drive nails into the studs whenever possible. (An electronic stud finder can help you with this)

Step 4:

INSIDE CORNERS – First cope the end of the second piece of trim, leaving the first piece of trim long. Next, start by fitting the coped end of the second piece of trim with the end of the first piece of trim. Then, measure, cut, and nail into place. NOTE: Remember the 1/16 inch rule of thumb.

Step 5:

OUTSIDE CORNERS – To miter outside corners, start by fitting the coped end of the trim first. Then mark the miter location with the piece in place. You may have to adjust the miter angles a little for a good fit. NOTE: A good rule of thumb is to make test cuts in scrap trim to insure acquires. Also remember that corners are rarely perfectly square.
