Nike Swim Size Chart

Swimwear can be a challenge to buy online, because fit really matters here. You want a swimsuit that stays put in front of a firehose and perfectly flatters your shape. Never fear; our Nike size charts are here to help.

If you already know your standard women's, girls' or boys' US swimsuit size, check out our women's, girls' or boys' size conversion charts to find the equivalent Nike size. The boys' and girls' size conversion charts also allow for approximate sizing by height and age.

For more precise sizing, follow our measuring guide for men's clothing or our measuring guide for women's clothing to measure your bust/chest, waist, hip, and torso. Then compare your body measurements to the tables below to find your perfect Nike swimwear size. We have measurement charts for women's one-piece swimsuits, women's separates (such as board shorts and bikinis), men's trunks and shirts, men's briefs, boys' swimwear, and girls' swimwear. Make sure to consult the specific chart you want!

When you've found your size, visit our Nike swim collection to shop for high performance men's, women's, and children's Nike swimwear from Outdoor Equipped today!
