When it comes to looking sharp in a mens suit, the key lies in the fit. Even the most luxurious fabric and on-trend style can fall flat if the fit isn’t spot on. That’s why knowing how to measure yourself for a suit is an absolute game-changer. Whether you’re shopping off-the-rack or going bespoke, accurate measurements ensure your suit complements your physique and personal style. Here’s a step-by-step guide to help you get it right.
Tools You’ll Need
Before diving into the measurements, make sure you’ve got the following:
-
A soft tape measure (the kind tailors use)
-
A full-length mirror
-
A friend to help, if possible (it’s tricky to do some of these alone)
-
A notepad or your phone to record the measurements
Step-by-Step Guide to Suit Measurements
1. Measure Your Chest at the Widest Part
-
Stand upright with your arms relaxed at your sides.
-
Wrap the tape measure around the fullest part of your chest, typically just under the armpits and across the shoulder blades.
-
Ensure the tape is snug but not tight. You should be able to slip one finger underneath.
-
Record the measurement in inches or centimetres.
Tip: For a modern fit, you may subtract half an inch, but for a more relaxed fit, stick to the exact number.
2. Record Your Natural Waist Size
-
Find your natural waist by bending sideways; the crease is your natural waistline.
-
Wrap the tape around this point, keeping it parallel to the ground.
-
Don’t suck in your stomach—you want a realistic measurement.
-
Jot down the number.
Why it matters: Your waist measurement determines how your trousers will sit, ensuring comfort and a clean silhouette.
3. Measure Your Hips at the Broadest Point
-
Stand with your feet together.
-
Wrap the tape measure around the widest part of your hips and buttocks.
-
Keep the tape level and snug, without pulling it too tight.
-
Note the measurement.
Tip: This step is crucial for slim-fit trousers, as they taper through the hips and thighs.
4. Note Your Shoulder Width
-
Stand straight and relaxed.
-
Measure from the edge of one shoulder to the edge of the other, passing over the base of your neck.
-
Make sure the tape follows the curve of your shoulders.
-
Record the measurement.
Why it matters: This determines how well the jacket’s shoulders will align with yours. An ill-fitting shoulder can make even the most expensive suit look cheap.
5. Measure Sleeve Length
-
Start at the edge of your shoulder, where the seam of a well-fitted shirt would sit.
-
Run the tape down to just past your wrist bone, where you’d like your sleeve to end.
-
Note the measurement for both arms, as they might differ slightly.
Pro tip: Ensure about half an inch of your shirt cuff peeks out when wearing the mens suit.
6. Record Your Neck Size
-
Wrap the tape around the base of your neck where a shirt collar would sit.
-
Leave enough space to fit two fingers between your neck and the tape.
-
Write down the number.
Why it matters: A well-fitted shirt collar frames your face and ensures comfort.
7. Measure Your Inseam
-
Wear shoes and stand straight.
-
Measure from the crotch seam down to the top of your shoes.
-
Note the measurement for both legs.
Tip: For a break-free modern look, the trousers should just graze the tops of your shoes. For a more classic look, allow for a slight break.
8. Note Jacket Length
-
Start from the base of your neck, where it meets the shoulders.
-
Run the tape down to the point where you want your jacket to end. This is usually just below the seat for a standard fit.
-
Record the measurement.
Pro tip: A jacket that’s too short can look awkward, while one that’s too long can drown your frame. Aim for balance.
9. Recheck for Accuracy
-
Go through each measurement again to ensure consistency.
-
If you’re unsure about any, measure a second or even third time.
-
Record the final numbers clearly.
Why it matters: Precision is everything. Even small discrepancies can impact the fit of your suit.
Additional Tips for a Perfect Fit
-
Understand Suit Styles: Decide whether you prefer a slim fit, regular fit, or classic fit. Your measurements might vary slightly depending on the style you’re aiming for.
-
Consider Posture: Stand naturally while measuring, as slouching or sucking in can lead to inaccurate results.
-
Check Sizing Charts: If you’re buying online, compare your measurements to the retailer’s size guide.
-
Seek Professional Help: If measuring yourself feels daunting, visit a tailor for precise measurements.
Why Accurate Measurements Matter
A well-fitted suit does more than make you look good—it boosts confidence, conveys professionalism, and enhances comfort. Whether it’s for a job interview, wedding, or formal event, a suit that fits perfectly ensures you’re always dressed to impress.
