Trim My Crib™Ten-foot ceilings and taller: scaling an accent wall so it looks right
Tall walls need bolder spacing and clear divisions. Two pieces of arithmetic make the planning easier.
A pattern that looks perfect on a standard bedroom wall can look fussy and thin when it is stretched up a two-story great room. Taller walls ask for larger elements, wider spacing and a deliberate horizontal division or two. The good news is that most of the planning is simple arithmetic you can do with a tape measure and a calculator.
How do you divide a tall wall?
One long-standing designer’s rule of thumb is to divide a wall’s height into thirds. A rail, a ledge or a change of treatment at one third or two thirds of the height usually looks more settled than one placed exactly halfway, which can cut a wall into two competing halves.
| Wall height | One third up | Two thirds up |
|---|---|---|
| 8 ft (96 in.) | 32 in. | 64 in. |
| 10 ft (120 in.) | 40 in. | 80 in. |
| 12 ft (144 in.) | 48 in. | 96 in. |
| 18 ft (216 in.) | 72 in. | 144 in. |
Simple division worked out for this guide. Adjust to window heads, door tops and furniture.
How do you space battens evenly?
For vertical battens with one at each end of the wall, the space between them is:
gap = (wall width − number of battens × batten width) ÷ (number of battens − 1)
Take a wall 168 inches wide (14 feet) and battens 2.5 inches wide. With 7 battens the gap is (168 − 17.5) ÷ 6 = 25.08 inches. With 9 battens it drops to (168 − 22.5) ÷ 8 = 18.19 inches.
Which looks better depends on height. On a tall wall the wider spacing often reads as calmer and more architectural, while tight spacing on a very tall wall can start to look like a texture rather than a pattern. Measure the wall at the floor, the middle and the top; if the numbers differ, the layout has to absorb the difference somewhere, usually at the ends.
Do the boards need to be bigger, too?
Often, yes. A batten or slat that looks substantial at eye level in a bedroom can disappear at 16 feet. A quick test is to tape strips of painter’s tape in the candidate widths onto the wall and look from across the room, and from the far side of the kitchen in an open plan.
What about picture-frame molding on a tall wall?
Use fewer, larger frames rather than more, smaller ones, and line their edges up with something already in the room: the top of a door, the sill of a window or the height of a kitchen island. Alignment is what makes a tall wall look designed rather than decorated.
Who needs a ladder plan?
Anyone working above about 10 feet. Tall great-room walls need proper scaffolding or ladders rated for the job and someone else in the room. If you are hiring the work, ask how the tall sections will be reached safely.
