If you’re looking for the appropriate size when shopping children’s swimwear for your child based on their weight, we recommend referring to our sizing charts on each product page. Our sizing information is provided in inches, as we believe it offers a more accurate measurement than relying solely on pounds. By consulting the sizing charts, you can find the best fit for your child’s measurements.
