What is Scale?
The size of motifs relative to the rapport and to the end use. Children's wear uses 2-4 cm motifs; adult apparel uses 4-10 cm; home textiles use 8-25 cm; statement upholstery uses 25-50 cm.
In detail
Scale matters because the eye reads pattern differently at different distances. A 1 cm ditsy floral looks tasteful on a man's shirt at conversational distance but disappears on a curtain at viewing distance of 2 meters. Production scale norms by category: children's wear 2-4 cm; adult apparel 4-10 cm; home textiles 8-25 cm; large statement pieces (drapery, upholstery) 25-50 cm. Always test full-scale on actual fabric — a flat-screen view at 100% misleads about how the pattern reads on a garment. Scale also interacts with repeat type: smaller scales tolerate block repeats well (the eye does not pick up the grid); larger scales benefit from half-drop or toss to break up the rhythm.
Example
The same peony motif at 4 different scales: 2 cm (ditsy children's wear), 6 cm (women's apparel), 15 cm (curtains), 35 cm (statement throw pillow). Each scale needs a different rapport size: 30 cm, 45 cm, 80 cm, 120 cm respectively.
