The ideal height for wainscoting depends on your ceiling height and personal preference. A common guideline is the “rule of thirds,” where wainscoting is installed to cover one-third of the wall height. For example, in a room with 9-foot ceilings, wainscoting would typically be around 3 feet tall. However, for a more dramatic look, especially in rooms with higher ceilings, it can extend to 5 or 6 feet. Consulting with a Toronto trim carpentry contractor can help you determine the best height based on your home’s proportions and design goals.
