Q: What pyjama size does a 5-year-old girl need?

A typical 5-year-old girl may wear size 5T or size 5 depending on her measurements and build. 5T suits girls in the roughly 107 to 112 cm height range who still carry toddler proportions through the seat and belly. Size 5 suits the same height range but with a longer inseam and no extra diaper ease. Measure height, chest, and waist before choosing, since age is only a starting point. If she's between sizes or growing quickly, size up.

Q: What is the difference between 4T and size 4 in girls' pyjamas?

4T is a toddler size, with a shorter inseam, extra room through the seat and belly, and no defined waist, built for children in training pants or diapers. Size 4 is the first numeric size, with longer sleeves and legs, more structure through the waist, and no diaper ease. Both cover roughly the same height range, 99 to 106 cm, but their body shapes differ. The right choice depends on her proportions. Always check the product's own listed measurements.

Q: How do I measure my daughter for pyjamas?

Always measure directly on the body, never over clothing, using a soft measuring tape. Height: barefoot, standing straight against a wall, crown to heel, in centimetres. Chest: tape around the fullest part, horizontal and flat under the arms, not pulled tight. Waist: around the natural waistline just above the navel, comfortably snug. Hips: around the fullest part of the seat, tape horizontal, particularly important for girls from size 8 onward. Compare all figures to this page's chart.

Q: Should I size up when buying girls' pyjamas?

Sizing up one from her age is a widely used guideline when buying children's pyjamas, especially if you're unsure. For girls in active growth phases, common between ages 4 to 6 and again around 9 to 12, sizing up buys three to four extra months of wear. Snug-fit cotton styles have less stretch and should be chosen by measurements rather than an automatic size up. Relaxed and fleece styles carry more ease, so sizing up by one stays comfortable.

Q: What pyjama size is right for girls aged 8 to 10?

Girls aged 8 to 10 typically wear size 8 to 10, corresponding to heights of roughly 128 to 140 cm. Growth rates vary significantly at this age, so two girls the same age can differ by a full size. From size 8 onward, hips become a meaningful measurement, so measure hips alongside height and chest. Size 8 generally suits girls around 128 to 133 cm, while size 10 suits those around 134 to 140 cm. Check each product's notes too.

Our girls' pyjama size guide helps you find the right fit before you order, covering sizes from toddler 2T through size 16. JuniorKids has dressed Canadian girls for over 30 years, and measuring first in centimetres means fewer exchanges.

How to Measure Your Daughter for Pyjamas

Always measure directly on the body, never over clothing. Five measurements matter for girls. Height: barefoot, standing straight, crown to heel. Chest: around the fullest part, tape flat under the arms, arms relaxed. Waist: just above the navel, snug but not tight. Hips: around the fullest part of the seat, tape horizontal. Inseam: crotch to ankle. Record everything in centimetres. Hips grow in importance from around age 8 to 10, once chest and hips stop tracking together.

Girls' Pyjama Size Chart by Age and Height

Toddler sizes 2T to 5T suit ages roughly 2 to 5, heights around 84 to 110 cm, with extra room through the seat and shorter sleeves. Numeric sizes 4 to 16 suit ages roughly 4 to 16, heights around 104 to 160 cm, with longer inseams and a defined waist. Hips are tracked as a measurement from size 8 onward. When chest and hips point to different sizes on this chart, size up to the larger for comfort and movement.

Toddler vs. Kids' Pyjama Sizing for Girls

T-sizes are built for toddlers: shorter inseams and sleeves, extra room through the seat and belly, no defined waist. Numeric sizes introduce longer proportions and waist shaping, tracking hips from size 8 onward. A girl measuring 99 to 106 cm may wear either 4T or size 4, depending on whether she still needs training-pant ease. Sleeves creeping above the wrist while the waist still fits signals numeric sizing is overdue. Sizing up one from her age is a useful baseline.

Understanding Canadian Girls' Pyjama Sizing Labels

Canadian girls' pyjamas use two parallel systems: toddler sizes 2T to 5T, and numeric sizes 4 through 16. The number on the tag is an age-based guide only, and a size 6 from one brand can differ by several centimetres from another. European sizing, marked in cm such as 92 or 98, refers directly to the child's height. Quebec parents often see both systems side by side. Brand cut also varies, so always check each product's own fit notes.

How Girls' Pyjamas Should Fit

Pyjamas should allow free movement in every direction, arms raised, legs bent, without pulling tight or riding up. Sleeves should reach the wrist with a little ease, and pant legs should reach the ankle without bunching. Two-piece sets are sized as a unit, so a chest-to-hip mismatch can create a fit conflict. When chest and hips fall in different sizes, prioritize the larger measurement. Snug-fit cotton follows the size chart closely, while relaxed or flannel styles carry more ease.

When to Size Up — Signs She Has Outgrown Her Pyjamas

Sleeves ending above the wrist and pant legs ending above the ankle are the earliest signals she's outgrown her pyjamas. A waistband pulled to its tightest setting, or leaving a red mark, tells the same story. Girls with early growth spurts, common between ages 8 and 12, can shift a full size every few months. A top lifting away from the waistband when arms are raised signals a length issue even when the chest fits. Size up when in doubt.
