| Style | Height | Effect |
|---|---|---|
| Classic wainscot | 32–38" (⅓ wall) | Traditional, aligns with chair rail |
| Tall wainscot | 42–48" | Entry halls, mudrooms; protects and grounds |
| Two-thirds wall | ~60" (⅔ wall) | The designer favorite; adds height and drama |
| Full wall | Floor to ceiling | Modern, architectural; pairs with a picture-rail cap |
16–24 inches between battens; 18 is the classic start. Wider reads modern, tighter reads cottage. Equal gaps matter more than the exact number.
One-third of the wall (32–38") for classic wainscot, two-thirds (~60") for drama, or full height for a modern room. Avoid the exact half-wall line.
1×3 (2.5") battens suit most walls; 1×2 is delicate, 1×4 is bold. Rails are typically 1×4, with an optional 1×2 top ledge.
gap = (wall − battens × batten width) ÷ (battens − 1), with a batten at each end. Pick the count whose gap lands nearest your target. That's exactly what this calculator does.
Primed MDF for painted walls; pine or poplar where corners take abuse; PVC in wet rooms. Skim or panel textured walls first so the field reads crisp.
