A well-fitted suit instantly elevates your look for weddings, business meetings, proms and formal parties. However, most online suit shoppers get ill-fitting pieces simply because they take wrong body measurements.
You don’t need a professional tailor to get precise suit numbers. With only a soft measuring tape and 5 minutes, you can measure every key part of your body at home. This complete step-by-step guide will walk you through every measurement you need for our men’s suit collection.
Key Tips for Accurate Results
- Wear a thin plain dress shirt, no thick sweaters or hoodies
- Stand straight, relax your shoulders, keep arms naturally at your sides
- Keep the tape horizontal, snug but not tight; slip one finger under the tape for comfortable space
- Do not suck in your belly or puff out your chest to fake slimmer sizes

1.Measure Your Chest (Jacket Core Size)
Lift both arms slightly, wrap the tape around the widest part of your chest (across nipples)
- Lower arms back down, keep the tape flat and parallel to the floor
- Record the number in inches, this is your jacket base size
- Common mistake: Measuring too tight will make the jacket feel cramped when you move your arms.
2.Measure Shoulder Width
Ask someone to measure from the outer edge of one shoulder bone to the other across your back
- Do not pull the tape too hard; follow the natural curve of your shoulders
- If shoulder seams hang past your arm bones, the suit will look oversized and sloppy.
3.Measure Natural Waist for Suit Trousers
Locate the narrowest point of your torso, around 1 inch above your belly button
- Wrap the tape gently around this spot, do not cinch tight
- This data matches our suit pant sizing and avoids tightness around your stomach when sitting.
4.Measure Sleeve Length
Rest one arm relaxed at your side, slightly bent
- Start the tape at your shoulder seam, drag down to your wrist bone
- A perfect suit sleeve should expose 0.5 inch of your dress shirt cuff.
5.Hip & Inseam Measurement for Pants
Hips: Stand feet together, measure around the fullest part of your hips and buttocks
Inseam: Measure from your crotch down to where you want the pant hem to sit
These two numbers guarantee your suit trousers fit comfortably without pulling or sagging.

Sizes are measured strictly and accurately, no big deviation
