دليل مقاسات بيجامات الأطفال: كيف تختار المقاس المناسب

Quick answer

Buy kids pyjamas by height first, then chest, and add 2–4 cm of growth room rather than sizing up a full size. Measure your child in thin clothing with a soft tape, keep the tape snug but not tight, and write the numbers down before you open a size chart. If your child sits between two sizes, choose the larger one for woven satin and the smaller one for stretchy TENCEL™.

Measure height and chest in three minutes

Stand your child against a wall without shoes, heels together, and mark the top of the head with a pencil. That number is your primary size driver. Then wrap a soft tape around the fullest part of the chest, under the arms, keeping it level all the way around. For younger children, also measure the natural waist (the crease when they bend sideways) because elastic waistbands sit differently on different body shapes.

Take measurements in the evening rather than first thing in the morning, and always over thin clothing or underwear. If your child is wriggling, measure twice and average the two numbers. Write height, chest and waist on a note in your phone so you can compare against any size chart without re-measuring.

• Height: shoes off, heels to wall, eyes forward
• Chest: fullest point, tape level, arms relaxed
• Waist: natural crease, not the top of the hip bone
• Inseam: from crotch to ankle bone for longer-leg styles

How much growth room is actually right

A common mistake is sizing up a full size to make pyjamas last longer. That usually backfires: shoulders slide, sleeves cover the hands, and the waistband sits too low to stay put overnight. Aim for 2–4 cm of ease in the chest and about 5 cm in height. That is roughly one season of growth for most primary-school-aged children.

If your child is between sizes, the fabric decides. Woven satin has almost no give, so go up. Knitted TENCEL™ and modal blends stretch slightly and drape, so you can stay with the smaller size if the chest measurement is within 2 cm of the chart. For a pyjama set for children who toss and turn, slightly more room in the leg is more comfortable than a tight cuff.

Fabric changes the fit more than the size label

Two pyjama sets in the same size can feel completely different depending on the weave. Satin is smooth and structured, which means it holds its shape but has minimal stretch. TENCEL™ Lyocell and Lenzing Modal knits are softer and more forgiving, so they follow the body rather than fighting it. If your child is sensitive to seams or tags, a smoother knit is usually the easier wear.

Fabric also affects how long a set stays wearable. Satin keeps its silhouette wash after wash, so a slightly larger size still looks neat. Knits relax a little with wear, which is another reason not to oversize them. Wash both according to the care label, and avoid hot dryers, which shrink fibres and undo your careful sizing.

Check the sleepwear safety basics before you buy

Fit is only half the decision. Snug-fitting pyjamas are safer than loose, flowing styles because there is less fabric to catch. Look for a close fit at the wrist and ankle, and avoid long dangling ties or oversized sleeves for children who move a lot in bed. If the set has piping or trim, check that it lies flat and does not rub.

Also confirm the return policy before you cut tags. Some final-sale pieces cannot be exchanged, so measure carefully first and keep the tags on until you have done a try-on. If you are buying as a gift, note the size you chose so the recipient can swap confidently.

Decision rules for choosing a kids pyjama size

• Start with height, not age: Age labels vary between brands. Use measured height as your first filter, then check chest against the chart. If height and chest point to different sizes, follow the chest for comfort and the height for length.
• Add 2–4 cm, not a whole size: A full size up usually means slipping shoulders and a waistband that will not stay put overnight. Aim for one season of growth room, not two.
• Let fabric decide between sizes: Satin has minimal stretch; TENCEL™ and modal knits are softer and more forgiving. Between sizes in satin: size up. Between sizes in TENCEL™: stay with the smaller size.
• Confirm the return policy before cutting tags: Final-sale pieces cannot be returned or exchanged, so a try-on with tags on is essential. Measure, try on, then wash.

Two kids sets and what their sizing means for you

• Gigi Kids Long Pyjama - White *Final Sale*: The Gigi Kids Long Pyjama is a checked satin set designed with the same detailing as the women's Gigi range, and it is marked Final Sale. Satin has little stretch, so measure the chest carefully and size up if your child is between sizes. Because it is final sale, check the size chart before removing tags.
• Petra Tencel™ Kids Pyjama Set - Navy with White Piping *Final Sale*: The Petra TENCEL™ Kids Pyjama Set is crafted from 100% Lenzing Modal and TENCEL™ certified sustainable botanical fibres, and it is marked Final Sale. The knit drape gives slightly more forgiveness than satin, so a child within 2 cm of the chart can usually stay in their usual size. Final sale means no returns, so confirm measurements first.
• Eva Lounge Tencel™ Pyjama Set - Navy with White Piping: The Eva Lounge Tencel™ Pyjama Set is made from 100% certified TENCEL™ Lyocell in navy with white piping, with a silk-like drape. If you want a matching adult-and-child look, the same TENCEL™ feel runs through the range, so you can size each person independently using the same height-first method.

Who each approach suits

Best for

• Parents buying a first kids pyjama set who want a fit that lasts a full season
• Children who sleep hot and need a breathable TENCEL™ or modal knit
• Gift buyers who need a reliable size without the child present

Not for

• Shoppers who want to size up two years for hand-me-down value, since oversized satin slips and bunches
• Anyone unwilling to measure, because final-sale kids sets cannot be exchanged
