What is K-tan Size?

K-tan sizes are a common sizing system used for baby clothing in many countries. The sizes are based on the baby's chest circumference, which is measured around the baby's chest at the level of the nipples.

The K-tan sizing system typically includes sizes from 0 to 6, with each size representing a specific range of chest circumferences. For example:

Size 0: 40-44 cm (16-17 inches)
Size 1: 45-49 cm (18-19 inches)
Size 2: 50-54 cm (20-21 inches)
Size 3: 55-59 cm (22-23 inches)
Size 4: 60-64 cm (24-25 inches)
Size 5: 65-69 cm (26-27 inches)
Size 6: 70-74 cm (28-29 inches)

K-tan sizes are often used for onesies, sleepers, and other basic baby clothing items. They provide a good fit for most babies and are widely available in stores.

How to Measure Baby for K-tan

Measuring your baby for K-tan size is straightforward:

Find the baby's chest circumference by measuring around the chest at the level of the nipples
Use a soft measuring tape or flexible measuring tool
Ensure the tape is snug but not tight - it should fit comfortably without pulling
Record the measurement in centimeters or inches

Tip: Measure your baby in the same position they'll wear the clothing. This helps ensure the best fit.

Once you have the chest circumference measurement, you can use our calculator to determine the appropriate K-tan size.
