How to Take Your Measurements for a Suit?

Getting the size right starts with accurate measurements.
If you're shopping for a suit online, preparation is key: the better your measurements, the better your suit will fit.

In this guide, we’ll walk you through a few simple steps to help you find your perfect size and avoid discomfort on the day.

How to Measure Your Shoulders for a Suit

Take accurate measurements
To measure shoulder width accurately, you’ll need a flexible tape measure and someone to help. Follow these simple steps:
Stand relaxed in a natural, upright position. Ask someone to measure across your shoulders using the tape measure. Start at the outer edge of one collarbone (where your shoulder ends), stretch the tape across your back, and stop at the outer edge of the opposite collarbone. Make sure the tape lies flat and straight — not too tight and not too loose.
Getting this measurement right helps ensure your suit jacket fits well at the shoulders — not too tight, not too wide — for a clean, flattering shape.
Shoulder fit
Perfect Fit:
  • The shoulder line should sit flush — not too wide, not too narrow. The shoulder seam should align cleanly with the top of your upper arm.
  • The lapels should lie flat across your chest, and the top button should close easily.
Shoulder fit
Too Small:
  • The jacket collar should sit snugly on your shoulder, not pull or stick out.
  • The jacket shouldn’t feel tight, flap open, or cause the lapels to lift.
Shoulder fit
Too Large:
  • Tip: Stand sideways next to a wall. If the shoulder padding touches the wall before your arm does, the jacket is too big.
  • In this case too, the lapels should lie flat and not flap out.

How to Measure Your Chest for a Suit

Chest measurement
Breathe normally, and use a flexible tape measure to take this key measurement.

Stand up straight. Place the tape around the fullest part of your chest — usually just below the armpits. Make sure the tape sits flat and runs parallel to the floor. It should feel snug but not tight — enough for accuracy, but not so much that it restricts your breathing. Don’t puff out your chest or hold your breath — normal breathing helps ensure the right measurement. Ask someone to help you read and record the result.

How to Measure Your Sleeve Length

Not too short, not too long – here’s how to get it just right for a blazer sleeves:

Stand upright with your arms relaxed at your sides.
The measurement starts at the outer shoulder.
Run the measuring tape straight down along the outside of your arm to your wrist.
The tape measure should lie flat against the arm and fit snugly — not tight. Note down the measurement once taken.

Perfect Fit:
  • Ideally, the jacket sleeves end at the wrists, one to a maximum of two finger widths in front of the base of the thumb, so that the shirt cuff can discreetly peek out underneath.

Too Small:
  • If the jacket fits perfectly, only the sleeves are too long or too short, you can simply have them adjusted by a tailor as needed.

Too Large:
  • Shirt cuffs should extend about 1.5 cm beyond the jacket sleeve – roughly a thumb’s width.

From waist to ankle: A guide to finding the right trouser length for men’s suits.

Guide to the correct trouser length
Now it’s your turn! Traditionally, suit trousers should rest gently on the shoe with a slight break – without touching the ground. A bit of creasing is fine, but the trousers should be neither too short nor too long. Before you start measuring, think about which shoes you'll wear most often with your new suit. Different styles can vary in heel height and may affect the ideal trouser length. Let’s get started with the measuring!

From crotch to ankle: Lay a pair of well-fitting trousers flat on the floor—ideally a pair of jeans or any sturdier fabric. Smooth out the leg so there are no wrinkles. Measure from the crotch seam down the inside leg to the very bottom of the hem. That measurement is your inseam—record it in centimetres.

Cotton, Wool, Linen – Fabrics That Make All the Difference in a Suit

A well-fitting suit is a timeless essential – it stands for elegance, style, and lasting quality. But beyond the fit, the fabric you choose plays a crucial role. Cotton, wool, and silk are three of the most popular materials for suits – and they can be the difference between a suit that’s simply nice and one that’s truly exceptional. Here’s what makes each fabric unique – and how to choose the right one for your look and lifestyle.

The versatility of linen suits makes them perfect for both formal occasions and relaxed, off-duty moments.

How Do I Take Proper Care of My Suit?

A high-quality suit is made to accompany you on many occasions – but to keep it looking its best, proper care is essential.

After wearing your suit, it’s important to air it out regularly. Hang it in a well-ventilated space to let any moisture and odours escape. This keeps your suit fresh and ready for your next occasion.

Avoid over-cleaning your suit. If it’s not visibly dirty, airing it out is often enough. For any stains, it’s best to treat them directly. Use mild stain removers and always follow the instructions carefully. Be sure to test the product on an inconspicuous area first to make sure it won’t damage the fabric.

Take extra care when it comes to washing your suit. In most cases, professional dry cleaning is recommended, as it ensures the suit’s delicate structure and fabric requirements are properly respected.

Remember – a suit is a valuable investment. With the right care, it will keep its sharp look and quality for years to come. Follow these care tips, and you can be confident your suit will always be ready to help you make a stylish, elegant impression.

What’s the Best Way to Store My Suit?

Is your suit looking its best? Then let’s make sure it stays that way! The ideal place for your suit is on a padded hanger that supports the shape of the blazer and helps prevent creases. Stored in a breathable garment bag, your suit will stay protected in the wardrobe – safe from sunlight that can fade colours or damage the fabric.

Good to see you again! Let your suit breathe regularly to release moisture and remove odours. Avoid over-washing to preserve the fabric and keep the colours looking sharp.

Travel in Style: How to Keep Your Suit Looking Sharp on the Go

We don’t believe in limits – and neither should your style. If you travel often and want to stay sharp on the go, don’t overlook your suit. Invest in a high-quality garment bag to protect it from dust and creases. When packing, gently roll your suit instead of folding it flat – this helps avoid deep wrinkles. Once you arrive, hang your suit on a padded hanger to let it fall back into shape. If needed, stop by a local dry cleaner to refresh and press it professionally. And just like that – you’re ready for your next stylish journey.
