Plan box panelling or battens: how many panels, how wide and how far apart.
How this works
Panels are spaced with the same gap between each box and at both ends, so panel width = (wall width – gap x (panels + 1)) / panels. A dado rail looks right at about one third of the wall height (90 to 100 cm on a 240 cm wall). Moulding is sold in 2.4 m lengths and we add 10% for mitres.
