Measure yourself properly the first time
Fit starts with numbers. We'll walk you through the measurements that matter—chest, waist, inseam, shoulder, and sleeve—so you can shop with confidence and stop guessing.
5 min read · IrisMost men wear the wrong size because they've never actually measured themselves. They guess based on what they've always bought, or they rely on a single brand's fit. That ends today.
All you need is a soft measuring tape (the kind tailors use), a mirror, and five minutes. We're going to get you five numbers that unlock better shopping decisions forever.
Measure in the clothes you'll actually wear—not naked, not in a heavy sweater.
Step one · 1 minute
Get the right tool
You need a soft fabric measuring tape, not a metal one. They're cheap (under $5) and essential for accuracy. If you don't have one, a piece of string works in a pinch—just mark it and measure against a ruler afterward. Avoid measuring over heavy layers; a t-shirt is ideal.
Keep the tape snug but not tight. You're measuring where fabric will sit, not cutting off circulation.
Step two · 2 minutes
Measure your chest
Stand straight in front of a mirror. Wrap the tape around the fullest part of your chest, keeping it parallel to the ground. Don't pull tight—the tape should sit flat and comfortable, like a shirt would. Take the measurement where the tape overlaps. This number is your chest measurement and the foundation for shirt and jacket sizing.
Breathe normally. If you suck in your stomach, the number is useless.
Step three · 2 minutes
Measure your waist
Measure at your natural waist—where your pants typically sit, not your belly button. Keep the tape parallel to the ground and snug but comfortable. This is the number you'll use for pants, shorts, and some jacket fits. Many men measure too low here; stick to where your actual waistband lands.
If you're between sizes, round up slightly. Waistbands stretch over time.
Step four · 2 minutes
Measure your inseam
This one's trickier solo. Wear the shoes you'll actually wear with pants. Stand straight and measure from the inside of your ankle bone up to your groin. If you have a friend, they can help from behind. Alternatively, measure a pair of pants that fit you well from the inside seam at the ankle to the crotch seam. This number determines your pants length.
Inseam varies wildly by shoe heel height and personal preference. A 30-inch inseam might hit differently in loafers versus sneakers.
Step five · 2 minutes
Measure your shoulders and sleeves
For shoulders, measure across the back from shoulder point to shoulder point (where the sleeve naturally ends). For sleeves, measure from the center back of your neck, across the shoulder, down to your wrist bone with your arm relaxed at your side. These numbers matter for jackets and dress shirts. Many men ignore sleeve length and regret it.
Sleeve length is personal. Some prefer a quarter-inch of wrist showing; others like it covered. Measure what you prefer.
Step six · 1 minute
Write it down and save it
Create a simple note on your phone with your five measurements: chest, waist, inseam, shoulder, and sleeve. Include the date. Revisit it annually or whenever your body changes. This becomes your personal fit reference—bring it when you shop in person, and use it when ordering online.
Screenshot it. Email it to yourself. You'll reference this more than you think.
How to know you've measured correctly
Your measurements should feel comfortable and honest. If a number seems wildly different from what you expected, remeasure—but don't adjust the tape to match your ego. The goal is accuracy, not flattery.
Questions at the mirror.
What if I'm between sizes?
Go with the larger size for comfort, especially in chest and waist. Tailoring down is easier than letting out. For inseam, round to the nearest half-inch.
Do I measure over a shirt or naked?
Measure over a fitted t-shirt—the kind you'd actually wear under clothes. This gives you real-world numbers that account for layering.
How often should I remeasure?
Annually or whenever your weight or fitness changes noticeably. Bodies shift; your measurements should reflect that.
Why do my measurements differ from store sizes?
Brands size inconsistently. Your measurements are universal; store sizes are not. Always check a brand's size chart against your actual numbers.
