The Ultimate Guide to Period Panties for Teens: Sizing and Styles

Starting your period is a big milestone, and having the right protection can make all the difference. Period panties for teens are a game-changer—they're comfortable, reusable, and provide reliable leakproof protection that lets teens go about their day with confidence. But with so many styles and sizes available, how do you choose the perfect pair?

In this guide, we'll walk you through everything you need to know about teen period panty sizing, the best styles for different activities, and what features to look for. Whether your teen is just starting her period or needs backup protection for sports and school, we've got you covered.

Why Period Panties Are Perfect for Teens

Period panties look and feel like regular underwear, but they feature built-in absorbent layers that trap menstrual flow. This makes them an ideal choice for teens who want a simple, no-fuss option that doesn't require inserting a cup or disc. They're also great for overnight protection or as backup when using a menstrual cup or disc.

For teens, comfort and discretion are key. Period panties are available in a variety of styles—from bikinis to boyshorts—so they can pick what feels most comfortable. Plus, they're reusable, which makes them an eco-friendly and cost-effective choice for families.

• Leakproof layers provide peace of mind during school, sports, and sleep.
• Reusable design saves money and reduces waste compared to disposables.
• No insertion required—perfect for teens who are new to period care.

How to Find the Right Size for Teens

Getting the right fit is crucial for both comfort and leak protection. Teen bodies change rapidly, so it's important to measure regularly. Use a soft measuring tape to measure the waist and hips, then compare with the brand's size chart. Most period panties are designed to fit like regular underwear, so if your teen wears a size 7 in girls' or a small in women's, she'll likely wear a small or medium in period panties.

If you're between sizes, it's usually better to size up for a more comfortable fit, especially if the teen is still growing. Many brands, including Saalt, offer size guides specifically for teens. Also, consider the absorbency level—heavier flow days may require a more absorbent style, but the fit should remain snug without being too tight.

• Measure waist and hips every few months during growth spurts.
• When in doubt, size up for a comfier fit.
• Check the brand's size chart for teen-specific guidance.

Popular Styles for Teens

Teens have different preferences when it comes to underwear styles, so it's great that period panties come in so many options. Bikini styles, like the Seamless Bikini — Non-Leakproof, are a fantastic everyday choice—they offer a smooth, invisible look under clothes and are perfect for school or hanging out with friends. For a sporty option, boyshorts provide extra coverage and are ideal for active days.

If your teen prefers a more minimal feel, a thong like the Leakproof Lace Thong might be appealing, though some teens may find thongs less comfortable for everyday wear. High-waist styles, such as the Seamless High Waist — Non-Leakproof, offer extra tummy coverage and a trendy look. The key is to let your teen choose what feels best for her body.

• Bikinis: great for everyday wear and under jeans.
• Boyshorts: extra coverage for sports and lounging.
• High-waist: stylish and supportive for all-day wear.

Leakproof Features to Consider

The main purpose of period panties is to prevent leaks, so look for features like moisture-wicking fabric, absorbent layers, and leakproof barriers. Saalt's Leakproof Seamless Bikini offers built-in protection that keeps you dry and comfortable, even on heavy days. For teens who are active, the Heavy Day Workout 3-Pack is designed to handle intense movement and higher flow, making it a great investment for sports practices or long school days.

Another thing to consider is the fabric. Cotton is breathable and gentle on sensitive skin, making it a popular choice for teens. The Leakproof Cotton Lace Trim Thong combines the softness of cotton with lace for a cute, comfortable option. Always check the care instructions—most period panties can be washed and reused for years.

• Look for moisture-wicking and absorbent layers.
• Choose cotton for breathability and comfort.
• Consider a multi-pack for convenience and value.

Tips for First-Time Users

If your teen is new to period panties, start by having her wear them on a light day or as backup with a tampon or cup. This helps her get used to the feel and understand how they work. It's also a good idea to have a few pairs on hand so she can change as needed throughout the day.

Explain that period panties are not meant to be worn all day without changing—just like regular underwear, they should be changed daily or more often if needed. With proper care, they'll stay in great condition for many cycles.
