Brand Threads Size Guide
At Brand Threads, we believe that the perfect fit is the foundation of comfort and confidence. Specialising in premium infant and toddler apparel, our sizing philosophy is built upon precision, durability, and the unique growth patterns of young children. We understand that dressing a newborn requires a different level of accuracy than outfitting a toddler, which is why our guides are meticulously detailed. Whether you are searching for the softest organic cotton onesies for a newborn or robust playwear for a growing toddler, our sizing systems are designed to minimise guesswork, ensuring that every garment provides the necessary room for movement while maintaining a snug, safe, and comfortable fit. Our collections are curated to accommodate rapid growth spurts, providing parents with the peace of mind that their little ones are dressed in clothing that is both functional and beautifully fitted.
How to Measure
To ensure the most accurate selection from our collections, please follow these measurement steps. For infants, we recommend focusing on height and weight, whereas for older children and adults, physical dimensions are key.
- For Infants & Newborns: Use a soft measuring tape to determine the baby's length from the top of the head to the heel. Accurate weight measurement is equally vital for ensuring the correct snugness of our newborn range.
- For Toddlers & Kids: Measure the circumference of the chest at the widest point, just under the armpits. For trousers, measure the waist at the narrowest part of the torso.
- For Footwear: Place the foot flat on a piece of paper and trace the outline. Measure the distance from the heel to the longest toe in centimetres to match our EU-based sizing precision. 'For Height (EU Sizing): For all European-standard items, measure the child's total height from head to toe in centimetres.
- Evening Measurements: We recommend measuring feet in the evening, as feet tend to swell slightly throughout the day, ensuring your footwear choice is never too restrictive.

Product-Specific Guidance
To ensure the longevity of your Brand Threads garments, please consider the following category-specific advice:
- Infant Essentials: Our newborn and preemie ranges are crafted from ultra-soft, breathable cotton. Because these items are designed for frequent changes, we recommend checking the weight guide closely to ensure a comfortable, non-restrictive fit around the waist and limbs.
- Toddler Playwear: For our 12m to 3-year collections, we prioritise durability. If your child is between sizes or particularly active, we suggest selecting the larger size to accommodate movement and potential growth spurts.
- Kids' Outerwear: Our jackets and heavier knits are designed for layering. When selecting sizes for children aged 4—12, consider the thickness of the layers they will wear underneath.
- Footwear: Our shoes are built on precise lasts. For athletic styles, ensure there is approximately 0.5cm to 1cm of space at the toe to allow for natural foot expansion during activity.
Sizing Tips
- Prioritise Weight for Newborns: For the first six months, a baby's weight is a more reliable indicator of fit than age alone.
- Use Height for EU Precision: When shopping our European-standard lines, always refer to the child's height in centimetres for the most accurate fit.
- Account for Growth: Children grow rapidly; when in doubt, particularly for trousers and jumpers, always opt for the larger size.
- Measure in the Evening: Always measure feet in the evening to account for natural swelling, ensuring footwear is never too tight.
- Consider Fabric Stretch: Our cotton knits offer moderate stretch, but structured denim or heavy outerwear will require a more precise measurement of the waist and chest.
- Check the 'Last': For footwear, remember that different shoe shapes (lasts) can affect width; if your child has a wider foot, consider sizing up.
- Layering Allowance: When selecting sizes for older children's tops, remember to account for the bulk of thermal layers or sweatshirts underneath.
