How To Measure A Suit

What should I consider when choosing a well fitted suit?

When choosing a well fitted suit, focus on how it fits your shoulders and body, as this makes the biggest difference in how it looks. The jacket should feel comfortable and not too tight, with sleeves showing a small amount of shirt cuff. Trousers should sit well at the waist and have a clean, neat shape that not too loose or tight.

How do I determine my correct suit size and fit?

To determine your suit size, start by taking a look at the sizes guides, which indicates chest measurement and jacket length. Then take key measurements of your chest, waist, shoulders, sleeve length, and inseam, and try the suit on to check comfort, proper sleeve cuff, and trouser break. You also want to consider the style weather that’s slim, tailored, or classic as each fits differently on the body.

How To Measure Jacket

  1. Chest: Measure around the fullest part of your chest.
  2. Overarm: With your arms by your side, measure from your shoulder in a straight line to the required length.

How to take suit measurements

How to measure suit chest size?

  1. Use a soft measuring tape.
  2. Stand naturally, arms relaxed at your sides.
  3. Wrap the tape around your chest, measure at the fullest part, just under your armpits and across your shoulder blades.
  4. Keep the tape level and snug, it should be close to the body but not tight.
  5. Record the measurement, this is your chest size, which determines your jacket size.

For a more comfortable fit, add about 1–2 inches to this measurement to allow movement and layering.

How to measure sleeve length for suit?

  1. Start at the shoulder seam place the tape where the sleeve meets the jacket shoulder.
  2. Measure to the wrist bone, extend the tape down your arm to just past the wrist bone, allowing for a small shirt cuff to show (about 1–1.5?cm).
  3. Keep your arm relaxed, don’t bend or stretch your arm; measure it naturally at your side.
  4. Record the measurement, this is your sleeve length for the jacket.

For a perfect fit, some people add half an inch for comfort if wearing thicker shirts underneath.

Where should suit sleeves fall?

Suit sleeves should fall so that a small portion of your shirt cuff shows, usually about 1–1.5?cm (½ inch) beyond the jacket sleeve.

  • If the sleeves cover your shirt completely, the jacket looks too long or ill-fitted.
  • If the sleeves sit too high, showing too much wrist, it looks awkward.

Can you give me tips on how to wear a suit properly?

  • Fit comes first – The jacket shoulders should sit well, sleeves should show a small amount of shirt cuff, and trousers should sit comfortably at the waist with a slight break at the shoe.
  • Button rules – For a two button jacket, only fasten the top button while standing. Never button the bottom one.
  • Trousers & shoes – Match the trouser break to your shoe style: slight break for dress shoes, minimal or no break for modern shoes.
  • Shirt & tie – Collar should fit snugly without being uncomfortable, tie should reach your belt buckle. Stick to classic colours and patterns for versatility.
  • Accessorise lightly – Pocket squares, cufflinks, and belts should complement, not compete.
