How far apart should board and batten be?

Most board and batten walls use gaps between 8 and 16 inches. There is no single right answer. The best gap depends on the room size, the ceiling height and how bold you want the wall to look.

This page starts in "gap I want" mode. Type the gap you like and the tool picks the batten count that comes closest, then makes every gap equal. If it has to move your gap, the result says by how much.

Units

Or type it in the feet box in one go, like 12'6 1/2.

Batten width

A 1x3 board is 2 1/2 in wide, a 1x4 is 3 1/2 in.

    Marks from the left

    Measure from the left edge of the wall. Make a pencil mark at each center, then set each batten on its mark.

      Center to center is the distance from the middle of one batten to the middle of the next. This tool counts battens and rails only. It does not count the wide boards or panels behind them. With no end battens, the gap at each end of the wall equals every other gap. Short offcuts from 10 and 12 foot boards work well for small trim pieces.

      Gap you ask for and what you get on a 12 ft wall (1x3 battens, end battens)

      The tool rounds to a whole number of battens, so the real gap is close to your target but not the same.

      Rules of thumb

      Tall ceilings take wider gaps. Small rooms take narrower gaps. Wide battens look right with wider gaps, and thin battens look right with narrow ones. Formal rooms such as a dining room or an entry hold up well with 8 to 10 inches. Living rooms and bedrooms often use 12 to 16.

      Test it on the wall

      Cut a few offcuts to the batten width and lay them on the wall with painter tape. Step back to the middle of the room. If the pattern looks too busy, widen the gap. If the wall looks empty, narrow it. Ten minutes of testing beats an hour of redoing nailed battens.

      Questions

      Is 12 inches a good gap for board and batten?

      Yes. It is the most common starting point. It reads as balanced in most rooms.

      Does the gap change if I use wider battens?

      The gap you choose stays the same, but the count drops, because each wider batten takes more of the wall.
