How to Measure Your Daughter
Girls 4–6X covers numeric sizes 4, 5, 6, and the transitional 6X (also written 6/6X) — a size larger than a 6 but smaller than a 7, built for girls who've outgrown a standard 6 but aren't ready for the 7–14 range. Combination sizes like 4/5 and 5/6 also appear from some brands and span two sizes for flexible fit. Because so many brands overlap here, measuring is much more reliable than relying on age alone.
Height: Stand your daughter against a wall with heels flat and barefoot. Measure from the top of the head to the floor.
Weight: Use a home scale. Weight is a useful cross-check for one-piece items (dresses, swimsuits, rompers).
Chest: Measure around the fullest part of the chest, keeping the tape level under the arms. Used for tops, dresses, and swim tops.
Waist: Find the natural waistline — the narrowest part of the torso, usually just above the belly button — and measure there. Used for dresses, bottoms, and swim bottoms.
Hip / Seat: Measure around the fullest part of the hips and seat. Used for pants, skirts, and leggings that need seat room.
Pro tip: If her measurements straddle two sizes, size up — it's much easier to belt, cinch, or roll than to size out of a too-small piece mid-season.
Pro tip: Dresses are often cut long at this age. If her height is at the top of the size range, the dress length will still work; if her height is at the bottom, check the length measurement before ordering.
Pro tip: Some brands in this department run large (Appaman, Mud Pie) and some run small (Limeapple). Check the Brand Notes on the product page before sizing.
