How to Measure a Room For Moulding

How to measure for moulding.

  • Measure the length of each wall, taking into account openings for windows and doors.

  • Remember to add ten percent to the sum total for mitering.

  • Moulding is available in a variety of lengths. Use longer lengths of moulding in larger rooms so that fewer cuts will be required.

How to Select the Right Size Moulding

While your choice of moulding style is a personal one, the size of the room and the height of the ceiling in the room play an important role in making moulding decisions. Lowe’s suggests you consider the following recommendations as a minimum size range to use based in particular to ceiling height.
