Estimated quantity12 battens (add one for the end)

Formula & assumptionsceiling(wall_width_inches / panel_coverage_width_inches)

Assumes one horizontal run of equal-width panels using effective coverage width. It does not account for openings, panel height, pattern matching, or extra waste.

Overview

Vertical battens spaced 16 in apart under a horizontal top rail, built from flat MDF boards. Farmhouse, craftsman and mudroom walls.

Why in bathrooms need a plan

Vertical battens spaced 16 in apart under a horizontal top rail, built from flat MDF boards. Use polystyrene molding; it does not absorb water.

Building the board and batten pattern

Fix the top rail level first, then hang the battens from it at 16 in spacing. Start from the center of the wall so the end gaps match.

Questions

How many battens for a 15 ft wall?

13 battens at 16 in spacing, plus a top rail across the 15 ft run.

How high should the chair rail be in a living room?

About one third of the ceiling height: 32 in on an 8 ft ceiling, 36 in on 9 ft and 40 in on 10 ft. Center the layout on the sofa or TV rather than the wall when furniture is off-center.
