Gap = (wall width − frames × frame width) ÷ (frames + 1), giving equal space at both ends and between frames. First frame center = gap + frame width ÷ 2. Measure from there outward by frame width + gap per frame.

Worked example

Wall 120 in wide, 3 frames of 16 in each. Click Calculate. Gap = (120 − 48) ÷ 4 = 18 in between frames and at both ends. First frame center = 18 + 8 = 26 in from the left edge. Mark, hang, done — perfectly even.
