Men's Size Guide

Find your perfect fit with our men's size guide. We carry multiple brands, so these charts use the most common waist, chest, weight and height measurements across our underwear and tops to help you shop briefs, trunks, tank tops, shirts and more with confidence.

All measurements show metric first (cm / kg), then imperial (in / lb) below. Sizing may vary slightly by style and brand.

How to Measure

Waist

Wrap a soft measuring tape around your natural waistline, just above your belly button.
Keep the tape parallel to the floor and snug but not tight.
Record the measurement and match it to the Waist column in the underwear chart.

Chest

Stand naturally and wrap the tape around the fullest part of your chest, under your armpits.
Keep the tape level across your back and relaxed, not pulled tight.
Record the measurement and match it to the Chest column in the top chart.

Fit Tips by Style

Underwear

Briefs — Sit at the natural waist with a close, supportive fit. Follow the waist chart directly.

Boxer Briefs — Offer mid-thigh coverage with light compression. Choose your true waist size.

Trunks — Shorter legs than boxer briefs but the same waist fit. Use your regular waist size.

Thongs & G-Strings — Minimal coverage. If you are between sizes, size down for a secure pouch.

Boxer Shorts — Looser, more relaxed fit. If you are between sizes, size up for extra comfort.

Tops

Tank Tops — Usually fitted around the chest and shoulders. Choose the size that matches your chest measurement.

Shirts — Standard fit follows the chest chart. If you prefer a relaxed fit or layer underneath, size up.

Male Bodysuits — Close-fitting one-piece. If your chest and waist measurements fall in different sizes, choose the size that fits your chest and check the waist stretch.

Frequently Asked Questions

What size men's underwear should I buy?

Match your waist measurement to the Waist column in our underwear chart. Each cell shows centimeters first and inches below, so pick the unit you prefer. If your measurement falls between two sizes, consider the style and your preferred fit.

What size men's top should I buy?

Measure the fullest part of your chest and match it to the Chest column in our top chart. If you are between sizes, choose the larger size for a more comfortable fit.

What if my measurements fall between two sizes?

For a snug, supportive fit, choose the smaller size. For a looser, relaxed feel, choose the larger size. When your measurements are inconsistent, always choose the larger size.

Do underwear and top sizes use the same size letter?

Yes, both use S, M, L, XL, XXL, but the measurement columns are different: underwear is based on waist, while tops are based on chest. Always check the correct chart for the garment you are buying.

Do different styles fit differently?

Yes. Compression styles like briefs and trunks fit closer to the body, while boxer shorts are roomier. Tops such as tank tops and bodysuits are more fitted, while casual shirts may be cut looser.

Are these sizes the same for every brand on UndiesForMen?

Most brands we carry follow this waist and chest grading. Minor differences may exist between fabrics or cuts, so always check the style notes on the product page.

Frequently Asked Questions

What is the difference between boxer briefs and boxers?

Boxer briefs offer thigh-length support, while boxers are looser with a relaxed short leg.

What fabrics are used?

Soft cotton, modal, and spandex blends that move with you and wick moisture.

How do I size boxer briefs?

Use your waist measurement against the size chart; a snug but not tight fit is ideal.

How do I care for them?

Wash cold, avoid bleach, and tumble dry low to preserve stretch.
