Polarn O. Pyret Size Guide
Polarn O. Pyret is a Swedish children's clothing brand renowned for high-quality, durable garments designed to grow with your child. The brand is celebrated for its generous sizing, particularly in length, with pieces typically running large compared to mainstream retailers. Polarn O. Pyret specialises in organic cotton basics, layering pieces, outerwear, and footwear that prioritise comfort, sustainability, and longevity. The fit is characteristically long through the body and sleeves with a slim profile, making it ideal for tall or naturally slender children. Many parents choose Polarn O. Pyret for the quality and the ability to pass items down through siblings.
How to Measure
- Chest: Measure around the fullest part of the chest, keeping the tape measure parallel to the ground and snug but not tight.
- Waist: Measure around the natural waist (the narrowest part), again keeping the tape horizontal and comfortable.
- Length: For tops and dresses, measure from the shoulder seam down to the desired hem length. For trousers, measure the inside seam from the crotch to the ankle.
- Sleeve Length: Measure from the back of the neck, across the shoulder, and down the arm to the wrist with the arm bent slightly.
- Foot Length: Have your child stand barefoot on a piece of paper. Mark the heel and longest toe, then measure the distance in centimetres.
- Age vs. Size: Note that Polarn O. Pyret ages (e.g. "age 2") indicate the upper limit; a child aged 2 years old should typically wear the "2 years" size, but may fit into "3 years" if tall or if you prefer room for growth.

Product-Specific Guidance
Organic Cotton T-Shirts & Basics: Polarn O. Pyret basics are made from certified organic cotton and are cut generously in the body and sleeves. If your child is between sizes, choose the smaller size, as the fabric has excellent stretch and durability. These garments hold their shape beautifully through multiple washes.
Layering Pieces & Jumpers: Long-sleeved layering items and jumpers are notably long through the torso and arms. This is intentional, allowing children to layer without excess fabric at the wrists or hem. Expect at least one size larger than comparable high-street brands; a child who wears age 3 in most brands may comfortably fit age 2–3 in Polarn O. Pyret.
Outerwear & Jackets: Polarn O. Pyret's windproof and waterproof jackets feature innovative Flexisize technology, which uses buttonhole elastic on the inside of the sleeves. This allows the jacket to expand by up to 1.5 sizes as your child grows. Purchase your child's current size and adjust the sleeve length using the markings on the elastic. The jacket comes fully expanded and should be shortened to the indicated size. Two adjustment points per sleeve ensure a perfect fit throughout your child's growth.
Trousers & Leggings: Polarn O. Pyret trousers and leggings are particularly long and slim-fitting. They are ideal for tall, slender children. The waistbands are designed for a snug fit without being restrictive. If your child is on the smaller side or typically wears clothes that fit wider through the hips, consider sizing up to ensure comfort around the thighs and seat.
Footwear: Polarn O. Pyret shoes and boots are well-made and durable. Always measure your child's foot length in centimetres and refer to the size chart above. Swedish sizing means the shoes are cut slightly wider through the forefoot than some Asian or American brands. Allow approximately 1 cm of growth room at the toe.
Sizing Tips
- Polarn O. Pyret runs large: Children typically fit one full size smaller than the age label suggests. A 3-year-old often wears age 2, and a 5-year-old may wear age 4. This is especially true for outerwear.
- Tall and slim fit: The brand excels for tall or naturally lean children. If your child is average height but wider-set, you may find pieces too long. Conversely, if your child is very tall and slim, Polarn O. Pyret offers exceptional length.
- Organic cotton quality: Items made from certified organic cotton are durable and improve with washing. Do not size down based on fit alone; the fabric softens and conforms to your child's body over time.
- Growth room: Because of the generous sizing, Polarn O. Pyret garments provide significant room for growth. Purchasing one size larger than your child currently wears will extend the lifespan by 6–12 months, making it excellent value despite the premium price.
- Flexisize jackets: If buying an outerwear jacket, consider the Flexisize range. The expandable sleeves mean a single jacket can serve your child for 2–3 years, making the investment worthwhile.
- Wash and care: Always follow the care label. Most Polarn O. Pyret items are machine-washable at 40°C. Organic cotton items may shrink very slightly on first wash; this is normal and the fabric will relax during wear.
- Leg length on trousers: Polarn O. Pyret trousers are notably long. Measure your child's inside leg and compare carefully to the product length. Many parents choose to have hems taken up; alternatively, folded hems or cuff-style bottoms work well for growing children.
