True to height. Our pieces are cut with room to move, so most families size by height first and only size up when a child is at the top of a height band or between two sizes. Leggings and joggers stretch; tops fit closer, so check chest measurements for those.

Measure height standing against a wall without shoes, from floor to the top of the head. Chest goes around the fullest part under the arms, waist at the natural waistline, hips at the widest point, tape snug but not tight. Measure every three to four months; children grow faster than the retail calendar.
