The math behind it
Wainscoting height = ceiling height x share of the wall
Frame area = wainscoting height – baseboard – top rail
Wall above = ceiling height – wainscoting height
A worked example

- Top rail width: 3.5 in
What we got
- Wainscoting height: 48 in
- Height of the frame area: 39 in
- Wall left above: 72 in
- One-third rule height: 40 in
- Center of the top rail: 46.25 in
- Share of the wall covered: 40 %
Tips from the job site
- Avoid a height that cuts a window in half. Line the top rail up with the sill.
- Avoid putting the top rail at the same height as the middle of the wall. A clear one-third or one-quarter looks better.
- In rooms with high ceilings, go taller than 36 in so the wainscoting looks in scale.
Common questions
What is the standard height for wainscoting?
Most wainscoting is 32 to 36 in tall. For tall ceilings, the one-third rule gives a better balance.
What is the one-third rule?
The wainscoting takes up one third of the wall height. On an 8 ft wall that is 32 in.
Does the height include the baseboard?
Yes. The height runs from the floor to the top of the top rail.
