Size chart

By considering the baby’s age and height, every parent can easily choose the right size clothes. At LiaaBébé, we strive to make sure our clothing sizes are proportional to the baby’s measurements.

Smaller babies should be measured lying down, while bigger babies are best measured standing up. This way, you can select the perfect size.

How to choose the right size sleeping bag?

Please refer to the Size Chart to choose the right size. It is not necessary to buy one size larger, as our goal was to create products that are proportional to size.


Choose your child according to their height:

(the first column is the height, the second is the size of the sleeping bag)

66cm -71 cm (Size 74)

72cm - 78cm (Size 80)

79cm - 84cm (Size 86)

85cm - 90cm (Size 92)

91cm - 97cm (Size 98)

98cm - 103cm (Size 104)

104cm - 110cm (Size 110)

  • Sleeping Bag with Footed Section:

The passé part should be about at the ankle, then you can pull it over the head of the foot, so the bag part (L) will reach about from the shoulder to the ankle.

All 0.5 TOG, 1.5 TOG and 2.5 TOG sleeping bags with gussets , plus the 74 and 80 size Sleeveless Star and Peach Blossom 1.0 TOG Bags

Correct use of the gaiter: folded over the foot at night or folded up (if the child is not using it). If you pull it above the knee, it may cause tension in the material.

We only recommend using the gaiter on our sleeping bags for sizes 74-80. It is not ideal for larger and especially mobile children because it can slip and become uncomfortable.

For larger sizes (86 to 104), we offer bamboo ankle socks that provide comfort and security without restricting movement. These socks are designed to keep little feet warm and allow for freedom of movement, whether in bed or around the house!

  • Sleeping Bags without Footed Section

All 1.0 TOG Sleeveless and Long Sleeve Sleeping Bags, except for the 74 and 80 size Sleeveless Star and Peach Blossom 1.0 TOG Bags

If you are still not sure what size to choose, write to us via chat and we will respond to you very quickly, within a few hours.
