Enter the wall width, your batten width, and a target spacing, and this board and batten calculator spaces the battens evenly, gives the exact gap, and totals the linear feet of material.
Estimate only — start and end battens are placed at the wall corners; adjust for windows and doors.
This is the same math as fence-post or baluster spacing. We divide the wall width (minus one batten width) by the sum of your desired gap plus a batten width, round to a whole number, and add one so there is a batten hard against each corner. The gap is then recomputed exactly — wall width minus all the batten widths, divided by the number of gaps — so it lands a little off your target but is identical everywhere.
Vertical linear feet is the batten count times the wall height. If you are adding a top and bottom horizontal rail, that adds two wall widths of material. Real accent walls also break at windows and doors, so treat this as the count for a blank wall and adjust sections around openings by eye.
Most accent walls use 12 to 16 inches between battens. Wider gaps read more modern; narrower gaps feel like traditional wainscot. Pick a target and let the tool even it out.
You accept a gap slightly different from your target. The tool fixes the batten count first, then divides the leftover space equally, so every gap matches.
Yes — a batten tight to each end wall frames the pattern. The count here already includes both end battens.
