Aden + Anais Size Guide
Aden + Anais specialises in soft, breathable cotton muslin wraps, swaddles, blankets, and clothing for newborns and infants. The brand is renowned for its gentle, natural fabrics and practical designs that prioritise comfort and ease of use for both baby and parent. Sizing across Aden + Anais products is typically offered in age-based categories (newborn, 0–3 months, 3–6 months, 6–12 months, 12–24 months) rather than traditional numerical sizes, reflecting the rapid growth phases of infants. All products are designed to fit generously to allow for layering and movement, with particular attention to soft seams and non-irritating construction.
How to Measure
- For infant clothing, measure your baby's chest by wrapping a soft measuring tape gently around the fullest part of the chest, keeping the tape parallel to the ground.
- Measure your baby's length from the top of the head to the soles of the feet while the baby is lying flat on a firm surface. A measuring mat or length rod is ideal for accuracy.
- Note your baby's current age in months and cross-reference with the age-based sizing categories provided.
- Always allow for growth; Aden + Anais wraps and clothing are intentionally cut generously, so sizing up by one age bracket is often appropriate for extended wear.
- When measuring for muslin wraps and blankets, take note of the product dimensions (typically given in centimetres) rather than fitted sizing, as these items are measured by length and width rather than infant measurements.
- Refer to the specific product label or hang tag for exact dimensions and recommended age ranges, as sizing can vary between different product lines within the brand.

Product-Specific Guidance
Muslin Wraps & Swaddles
Aden + Anais muslin wraps are the cornerstone of the brand's offering. The classic 120 × 120 cm square wrap is versatile enough for newborns through toddlerhood. For parents who anticipate frequent use or prefer larger formats for pram draping and play mat coverage, the 150 × 150 cm version offers extended dimensions without a significant weight increase. Muslin wraps are intentionally oversized to allow for secure swaddling across growth phases; a newborn wrap will comfortably serve a 6-month-old. The lightweight, breathable cotton construction makes these suitable for year-round use.
Swaddle Clothing & Sleepwear
Aden + Anais swaddle clothing (including sleep sacks and lightweight sleep bags) is sized by age rather than numerically. Choose based on your infant's current age bracket and anticipated growth. The brand's signature soft cotton ensures skin-friendly construction; if your baby has sensitive skin or eczema-prone tendencies, these garments are often recommended by healthcare professionals. Sizing up one age category is common if you intend the garment to serve across an extended period (e.g., purchasing 3–6 month sizing for a newborn with the expectation of wear through 6 months).
Bodysuits & Tops
Short-sleeved and long-sleeved bodysuits follow the same age-based sizing convention. These are designed to layer beneath heavier clothing or worn alone in warmer months. The generous cut allows for nappy changes without removing the garment entirely. Bodysuits typically feature snap fasteners at the shoulder and nappy area for quick changes.
Blankets & Dream Blankets
Dream blankets are lightweight quilted blankets smaller than traditional muslin wraps, ideal for floor play, pram use, and travel. Their reduced dimensions (approximately 75–90 cm × 100–120 cm) make them portable whilst still providing adequate coverage. These are particularly useful as transition items when infants outgrow traditional swaddling.
Footwear & Booties
Aden + Anais booties and soft shoes are sized by age category (newborn, 0–3 months, 3–6 months, 6–12 months). These are designed with soft, non-slip soles and flexible uppers that accommodate rapid foot growth. Measure your baby's foot length in centimetres and cross-reference with the age category; do not size up aggressively in footwear, as loose-fitting booties may slip off or pose a safety risk.
Sizing Tips
- Age-based sizing is approximate. Individual infant growth varies widely. Babies born prematurely or those with lower birth weights may fit newborn sizing for an extended period, whilst larger infants may skip directly to 0–3 month sizing. Always verify chest and length measurements against the chart.
- Aden + Anais wraps are generously cut by design. A 120 × 120 cm muslin wrap will serve from newborn through toddlerhood. There is no need to purchase multiple sizes unless you prefer to have several wraps on rotation for laundering.
- Layer with growth in mind. Because wraps and blankets are unsized, they naturally accommodate growth. Purchase one or two sizes and rely on layering with additional blankets or garments as your baby grows rather than replacing wraps frequently.
- Consider climate and seasonality. Muslin wraps are lightweight and breathable, ideal for warm weather and indoor use. In colder months, pair them with heavier quilts or blankets. The brand offers seasonal collections (e.g., thicker quilts in autumn/winter) to suit regional climates.
- Check product labels for care instructions before sizing. Aden + Anais products may shrink slightly with washing. Review the manufacturer's care label and expected shrinkage (typically minimal with gentle washing) when deciding whether to size up.
- Soft seams and tagless construction are standard. Aden + Anais prioritises sensitive skin with flat seams and printed (rather than woven) labels. Sizing loosely is unnecessary for comfort; choose the size closest to your baby's current measurements.
- Purchase muslin wrap sets strategically. A set of three or four 120 × 120 cm wraps in different prints/colours is practical for most households. This allows for continuous rotation whilst others are in the wash, reducing the need for frequent laundering.
- Footwear sizing is snug by design. Aden + Anais booties and soft shoes are meant to stay on; do not size up to accommodate growth, as loose footwear may slip off. Instead, replace as your baby's foot length increases by 0.5 cm or more.
