Key Takeaways:
- Fit Matters: Choosing the correct underwear size improves support, comfort, and overall wearability.
- Measure, Don’t Guess: Waist measurements in inches are more reliable than pant sizes when selecting the right fit.
- Material Counts: Certified organic cotton offers soft, breathable comfort without harsh chemicals or unnecessary synthetics.
At NADS, we’ve redefined what men’s underwear should be, clean, conscious, and built for real comfort. With underwear made from certified organic cotton, designed without harsh chemicals, and crafted to minimize microplastics, we don’t follow trends, we set new standards. We're not here to impress with gimmicks or unnecessary tech, we're here to deliver underwear that actually feels good, wears well, and respects your body.
Still, even the best underwear won't feel right if you’re wearing the wrong size. The truth is, most guys don’t give much thought to sizing, until discomfort makes them pay attention. Underwear that's too tight may dig, restrict, and irritate. Too loose, and you're stuck with sagging fabric and constant adjustments. The fix? It’s not complicated, it’s just about knowing your waist size, checking a real size chart (not guessing based on your jeans), and choosing a cut that works for your body and lifestyle.
In this piece, we’ll break down how to choose the right size underwear, how to measure properly, and what to know before you buy, so your next pair actually fits the way it should.
Why The Right Underwear Size Matters
Wearing the right size underwear isn’t just about comfort, it supports your body properly and helps your underwear last longer. Underwear that’s too tight may restrict movement, cause skin irritation, or dig into your waist and thighs. Too loose, and you’re dealing with bunching, slipping, and a lack of support throughout the day.
At NADS, we design underwear that fits like it should: comfortably snug without squeezing, with enough give to move naturally with your body. Choosing the right size helps you get the most out of our boxer shorts and boxer briefs, keeping you focused on your day, not adjusting your waistband.
Relax in comfort with the Boxers Collection. These lightweight and breathable designs are perfect for lounging or daily wear.
How To Measure Yourself For Underwear
Getting the right fit starts with knowing your measurements. You don’t need any special tools, just a soft measuring tape and a few minutes.
Waist Measurement
Wrap the tape measure around your natural waistline, that’s usually just above your hips, where the waistband of your underwear normally sits. Make sure the tape is snug but not tight, and always measure on bare skin for accuracy.
Hip Measurement (Optional But Helpful)
For a more tailored fit, especially with boxer briefs, measuring around the fullest part of your hips may help. This is usually about 7–9 inches below your natural waist, depending on your body type.
Check In Inches
At NADS, our size guide is based on inches, not pants size, because pant sizing can vary wildly from brand to brand. Measuring ensures you’re choosing based on your actual body, not a vague label.
Understanding Underwear Size Charts
Once you have your measurements, it’s time to match them to the right size. Most brands (including us at NADS) offer detailed size charts that convert waist measurements into standard sizes like Small, Medium, Large, etc.
Why You Shouldn’t Guess
A size Medium in one brand may fit like a Small or Large in another. That's why relying on actual inch measurements, not your usual pants size or what “feels right”, helps you land on the most accurate fit.
How NADS Sizes Work
Our boxer shorts and boxer briefs are designed to sit comfortably on your waist without riding up or sliding down. We provide a clear sizing guide on every product page, so you can find your ideal fit based on your waist measurement in inches.
Between Sizes?
If you fall between sizes, consider how you like your underwear to fit. Prefer a looser feel? Size up. Want a snugger, more supported fit? Go with the smaller of the two, our materials are soft, flexible, and designed to move with you.
Boxer Shorts Vs. Boxer Briefs: Which Fit Is Right For You?
Both boxer shorts and boxer briefs offer distinct fits, and which one works best depends on your lifestyle, body type, and personal preference. At NADS, we offer both, with designs focused on comfort, support, and breathability.
Boxer Shorts
These offer a more relaxed fit with extra room in the leg and seat area. They’re ideal for lounging, sleeping, or anyone who prefers a looser feel. Our boxer shorts are cut to avoid bunching while still giving you that open, airy fit.
Boxer Briefs
A snugger, more supportive option that stays close to your body. Boxer briefs are a great choice for daily wear, movement-heavy days, or when you want everything held comfortably in place without shifting.
What To Choose
If you like more freedom and airflow, go for boxer shorts. If you’re after support and a closer fit, boxer briefs may be the better pick. Either way, our certified organic cotton and construction made without harsh chemicals keeps both options breathable and skin-friendly.
Common Sizing Mistakes To Avoid
Even with the best intentions, it’s easy to choose the wrong size. Here are a few common mistakes that may lead to discomfort, and how to avoid them.
Relying On Pants Size
Pants sizes vary from brand to brand and often don’t reflect your actual waist measurement. Always measure with a tape to get a more accurate size.
Ignoring Fabric Stretch
Some men size down, thinking tighter underwear means more support. But that may lead to restriction and irritation. At NADS, our underwear is built to stretch just enough to move with your body, not dig into it.
Not Considering Body Changes
Weight can shift, even slightly. If it’s been a while since you last measured, take a fresh waist measurement before reordering. What fit last year may not be your best fit today.
Skipping The Size Chart
Every brand is different. Always check the size chart instead of assuming your usual size will fit across the board. Ours is designed to help you choose with accuracy.
Choosing Comfortable, Harsh Chemical-Free Underwear
Comfort isn’t just about size, it’s also about what your underwear is made of. Many conventional options use toxic synthetic materials or fabrics treated with harsh chemicals that may irritate the skin, trap heat, or disrupt airflow.
At NADS, we believe what’s against your skin all day should be as safe as possible.
Certified Organic Cotton
Our underwear is made from certified organic cotton, a breathable, skin-friendly material that feels soft without relying on unnecessary additives. It’s grown without harsh chemical pesticides and processed to retain its natural comfort and purity.
Designed For Everyday Comfort
No labels that itch, no waistbands that dig, and no gimmicky features. Just smart design and thoughtful fabric choices. We also aim to use as few microplastics as possible, keeping your skin, and the planet, in mind.
Choosing the right fabric is just as important as choosing the right fit. With the right size and the right material, you’re set up for all-day comfort without compromise.
Final Tips Before You Buy
Finding your perfect underwear fit doesn’t have to be complicated. A few quick checks before you hit “add to cart” may save you from discomfort later.
Double-Check Your Measurements
Even small changes in weight or muscle tone may affect how your underwear fits. Measuring again, especially if it’s been more than a few months, helps ensure you’re buying the right size for how your body is today.
Look At The Size Chart, Not Just The Label
A size label doesn’t tell the full story, especially when sizing standards vary across brands. Always go by actual waist measurements and compare them to the brand’s sizing chart, not the size you think you usually wear.
Know What You Like
Your preferred fit makes a big difference in how comfortable you feel throughout the day. If you value more room and movement, boxer shorts may suit you better; if you prefer a supportive, close-to-body fit, boxer briefs are likely the right call.
Choose Certified Organic Cotton
Certified organic cotton offers breathable softness without the harsh chemicals found in conventional fabrics. Choosing underwear made with safer, more natural materials supports both your comfort and your skin’s long-term health.
Final Thoughts
Choosing the right size underwear doesn’t have to feel like a guessing game. With a simple waist measurement and a few minutes reviewing a size chart, you’re already halfway to a more comfortable, better-fitting pair.
At NADS, we make boxer shorts and boxer briefs designed to feel good, wear well, and without harsh chemicals. Whether you’re updating your drawer or trying something new, the right fit, paired with certified organic cotton, may make all the difference in how you feel every day.

Frequently Asked Questions About The Size Of Underwear I Should Buy
How often should I remeasure my waist for underwear sizing?
It’s a good idea to remeasure every 6–12 months, especially if your weight fluctuates or your activity level changes. Even minor shifts in body composition may affect fit.
Is it normal for different brands to fit differently even if the size is the same?
Yes, sizing can vary widely between brands due to differences in cut, fabric, and design. Always check each brand’s specific size chart.
Can wearing the wrong size underwear affect circulation?
Underwear that’s too tight around the waist or thighs may restrict blood flow over time. Choosing the right size helps support healthy circulation and comfort.
Do I need to size up if I’m between two sizes?
Not necessarily, it depends on your personal fit preference. Some men prefer a snug fit, while others choose a bit more room for ease of movement.
What signs indicate that my underwear is the wrong size?
Bunching, riding up, constant adjusting, red marks on the skin, or sagging fabric are all signs your underwear may not fit properly.
Should I size differently for boxer shorts and boxer briefs?
The size may stay the same, but the feel is different, boxer briefs fit snugger, while boxer shorts are looser. Go with what suits your comfort level and movement needs.
Can the fabric affect how a size fits?
Yes. Some fabrics stretch more than others, and natural materials like certified organic cotton fit more naturally without relying on elastic stretch.
What if I’m buying underwear as a gift, how can I choose the right size?
Try to find out the person’s waist measurement or pants size, then cross-reference it with the brand’s size chart. When in doubt, consider going up a size for comfort.
Why does underwear shrink after washing, even when I follow the care instructions?
Natural fibers like certified organic cotton may tighten slightly after the first wash. Buying the right size helps ensure a comfortable fit even after laundering.
Can I return underwear if it doesn’t fit?
This depends on the brand’s return policy. At NADS, we recommend checking our return and exchange information before purchasing to understand your options.
