Introduction

Ever wondered why some guys look like they've stepped off a movie set, while others seem to be drowning in fabric? The secret lies in the suit measurements! Did you know that a properly fitted suit can make you appear up to 10 pounds lighter and 2 inches taller? It's true! Well, maybe. In this guide, we'll unravel the mystery of suit measurements, ensuring you'll never settle for an ill-fitting ensemble again. From collar to cuff, we've got you covered – literally! You’re about to dive into everything you should know about suits and suit measurements.

Understanding the Basics of Suit Measurements

Suit measurements are specific dimensions taken of a person's body to ensure a proper fit when tailoring or purchasing a suit. These measurements are crucial for achieving a well-fitted, comfortable, and stylish appearance.

These are the main suit measurements that you will need to take in order to have a proper fitting suit:

Chest: Measured around the fullest part of the chest. Important for determining jacket size and ensuring proper fit across the upper body.
Waist: Measured around the natural waistline. Critical for both jacket and trouser fit, affecting comfort and overall silhouette.
Sleeve length: Measured from shoulder to wrist. Ensures proper sleeve length, with cuffs typically ending at the wrist bone.
Shoulder width: Measured from shoulder point to shoulder point. Crucial for jacket fit, as ill-fitting shoulders can't be easily altered.
Inseam: Measured from the crotch to the ankle. Determines trouser length and break (how the pants fall on the shoes).
Outseam: Measured from the waist to the ankle along the outer leg. Helps ensure proper trouser length and proportion.
Neck: Measured around the base of the neck. Important for collar fit on dress shirts worn with suits.
Hip: Measured around the fullest part of the hips. Ensures proper fit of trousers and jacket around the seat area.

Off-the-rack vs. Made-to-measure vs. Bespoke

There are many terms thrown around when it comes to purchasing suits. Searching online you will find Off-the-Rack, Made-to-Measure and Bespoke. Off-the-Rack is exactly what it sounds like. You go into a department store and purchase the best fitting suit that you can find. There are no altercations with these suits besides maybe the complementary hemming if the pants are too long. These suits usually do not fit individuals well and where most men will stop. But if you are reading this post then you are not the average man.

Next, we have made-to-measure suits. Made-to-measure suits are tailored to you but do not have a lot of customization. They are created from a preexisting pattern that gets adjusted to your measurements. Think of companies like Suit Supply and Indochino. Made-to-measure suits usually have 1-2 fittings, partially machined made with some hand finishings and typically take 4-8 weeks to complete. These suits are more affordable than bespoke, but pricier than off-the-rack.

Bespoke suits on the other hand are completely made from scratch for each client. You can customize every aspect of the suit to your exact specifications. Bespoke suits involve multiple fittings, often more than 3 for perfect adjustments. These suits are predominantly hand sewn with meticulous attention to detail. The pattern that is drafted will be unique to you and can take 2-3 months or longer to complete. Due to the fine craftsmanship of bespoke suits, they can be very expensive. I tend to see the cost for a bespoke suit around $5,000 and up.

Both made-to-measure and bespoke suits are far superior to off-the-rack suits. They will fit you properly and bring you a newfound level of confidence. Made-to-measure suits are a great start in your sartorial journey but, if you have the budget, bespoke suits are the pinnacle of tailoring craftsmanship and personalization.

Essential Measurements for a Well-Fitted Suit

Chest Measurement:

Wrap the tape measure around the fullest part of your chest, usually just under the armpits and over the shoulder blades. Keep the tape parallel to the ground and breathe normally.

This is the primary measurement for determining jacket size. It ensures the jacket fits comfortably across the chest without pulling or sagging.

Waist and Hip Measurements:

For your waist you want to measure around your natural waistline, typically just above the belly button. To measure your hips, you want to measure around the fullest part of your hips and buttocks.

These measurements ensure comfort and proper drape of both the jacket and trousers. They're crucial for avoiding an unsightly fit in the midsection and seat areas.

Shoulder Width:

Measure from the outer edge of one shoulder to the other, across the upper back.

This is the foundation of a great-fitting jacket. The shoulder seams should align with your natural shoulder edges. Proper shoulder fit is crucial as it's one of the hardest areas to alter.

Sleeve Length:

Measure from the shoulder seam to just past the wrist bone.

Achieving the perfect cuff reveal is about balance and can be tricky and will change depending on your jacket. Ideally, about 1/4 to 1/2 inch of shirt cuff should be visible beyond the jacket sleeve when standing with arms at your sides.

Jacket Length:

Measure from the base of the collar to the bottom hem of the jacket.

Balancing proportions for your body type is key here. Generally, the jacket should cover your seat and end around the middle of your thumb when your arms are at your sides. However, this can vary based on current fashion trends and personal preference.

Trouser Measurements for a Sharp Look

Waist and Seat Measurements:

For measuring your waist see previous section. To measure your seat, you will wrap the tape measure around the fullest part of your buttocks.

Here are a few tips to ensure a good fit: The waist should be snug but not tight, allowing you to comfortably insert two fingers. The seat should have enough room to avoid pulling or sagging, while maintaining a smooth line. A proper balance ensures comfort when sitting and standing, without compromising the trousers' shape.

Inseam and Outseam:

Inseam you measure from the crotch to the desired trouser bottom and for the outseam you measure from the top of the waistband to the desired trouser bottom along the outer leg.

Here are some tips for getting the length just right: Inseam determines where the trouser ends relative to your shoes. Outseam ensures proper proportion and helps determine the rise (distance from waist to crotch).

Thigh and Knee Measurements:

Measure around the fullest part of your thigh. For your knee measure around your knee while slightly bent.

Here are some tips for ensuring comfort and style: Thigh measurement ensures enough room for movement without excess fabric. Knee measurement allows for a natural taper from thigh to ankle.

Break:

The break refers to how the trouser bottom falls on your shoes.

Deciding which break is right for you:

No break: Trouser barely touches the shoe, showing ankle when walking. Modern and sleek.
Slight break: Small fold of fabric when standing. Versatile and classic.
Medium break: Noticeable fold at the front of the trouser. Traditional look.
Full break: Multiple folds at the front. A more relaxed, casual appearance.

The choice of break can significantly impact the overall look of your suit:

A shorter length (no break or slight break) creates a modern, tailored appearance.
A longer length (medium or full break) offers a more traditional or relaxed look.
Your height, build, and personal style should influence your choice of break.

How to Take Your Own Suit Measurements

Tools you’ll need for accurate measurements:

Flexible tape measure

Notepad and pen

A well fitting dress shirt

A pair of dress shoes

Optional: A friend to help

Step-by-step guide to measuring yourself at home:

Chest:

Wrap the tape around the fullest part of your chest, under your armpits.

Keep the tape parallel to the ground and breathe normally.

Waist:

Measure around your natural waistline, typically just above your belly button.

Don't suck in your stomach; keep it relaxed for an accurate measurement.

Hips:

Measure around the fullest part of your hips and buttocks.

Shoulder width:

Measure from the end of one shoulder to the other across your upper back.

The end of the shoulder is where the horizontal plane of your shoulder meets the vertical plane of your upper arm.

Sleeve length:

Start at the shoulder seam, measure down your arm to your wrist.

Bend your elbow slightly to ensure proper length when moving.

Inseam:

Measure from the crotch seam to the bottom of your ankle.

It's best to measure this on a pair of well-fitting trousers.

Outseam:

Measure from the top of your waistband to the bottom of your ankle along the outside of your leg.

Neck:

Measure around the base of your neck, where a collar would sit.

Add about 1/2 inch for comfort.

Common pitfalls to avoid:

Pulling the tape too high

Measuring over bulky clothing

Not keeping the tape measure level

Guessing at measurement points

Rounding numbers: always record exact measurements.

Measuring yourself without assistance: some measurements can be difficult to take accurately on your own.

When to seek professional help for measurements:

For bespoke or high-end made-to-measure suits
If you’re unsure about your measurements

If you have a non-standard body type

For special occasions: weddings for example

If you’re new to tailored clothing

If you’re between sizes

Even if you are taking your own measurements, it is often wise to have them verified by a professional before making a significant purchase. Many tailors and suit shops have complementary measurement services or services for a small fee.

Understanding Tailoring Terms and Alterations

Common tailoring vocabulary:

Let out/Take in: Adjusting the size of a garment by expanding or reducing the seams.
Hem: The folded and sewn edge at the bottom of sleeves or trousers.
Break: How the trousers leg falls on the shoe.

Taper: Gradually narrowing a garment, typically in the legs or sleeves.

Dart: A folded and sewn triangular shape to create contours in fabric.

Cuff: The turned-up hem at the bottom of trousers.

Pitch: The angle and positioning of the sleeve in relation to the armhole.

Types of alterations that can improve fit:

Jacket alterations:

Shorten/lengthen sleeves
Take in/let out waist
Adjust shoulder width
Shorten jacket length
Adjust collar

Trouser alterations:

Hem length
Waist adjustment
Seat adjustment
Taper legs
Add/remove cuffs

Cost considerations for different types of alterations:

Prices can vary widely depending on location and tailor, but here’s a general guide:

Low cost ($10-$30):

Hemming trousers
Shortening sleeves
Waist adjustments on trousers

Medium cost ($30-$75):

Taking in/letting out jacket waist
Tapering trouser legs
Adjusting seat trousers

High cost ($75+):

Adjusting shoulders
Major jacket length alterations
Significant changes to jacket structure

When to alter vs. when to buy a new suit:

Alter when:

The suit fits well but needs minor adjustments.
Alterations needed are within the scope of what can easily be changed (ex. hemming, sleeve length, waist adjustments).
The suit is good quality and worth investing in alterations.
You’ve changed size slightly but the overall fit is still good.

Buy new when:

Major alterations are needed, approaching or exceeding the cost of a new suit.
The shoulders of the jacket don’t fit properly
You’re significantly changed size, affecting the overall proportions of the suit.

A good tailor can seem like a wizard in his or her abilities, but there are still limits to how much a suit can be altered while maintaining its shape and style. It is better to buy a new suit that fits well from the start rather than trying to alter a poorly fitting one.

The Impact of Fabric and Style on Measurements

How different fabrics affect fit and drape:

Wool: The most common suit fabric. It drapes well, has natural elasticity and recovers from wrinkles easily. Different weights affect seasonal comfort and drape.
Cotton: Less forgiving than wool and tends to wrinkle more. It’s cooler but may not drape as smoothly.
Linen: Very lightweight and perfect for warmer climates. It is breathable, but wrinkles very easily (embrace the wrinkle). Linen tends to be more relaxed and have a more flowy drape.
Synthetic blends: I strongly recommend not buying synthetic blends. They do not last as long as natural fibers and aren’t the best for the environment. However, they can improve wrinkle resistance and durability (sort of) but may affect breathability. Often a closer fit due to inclusion of stretch.
Cashmere: Luxurious and soft, drapes beautifully but can be less durable.

Suit styles and their influence on measurements:

Slim fit:

Narrower cut through chest, waist and legs
Higher armholes and narrower sleeves
Shorter jacket length
Requires more precise measurements to avoid pulling or tightness

Classic fit:

More room in the chest, waist and legs
Lower armholes and fuller sleeves
Traditional jacket length
More forgiving in fit, allows for easier movement

Modern fit:

A middle ground between slim and classic
Tailored but not tight
Slightly shorter jacket length than classic

Seasonal considerations for suit measurements:

Summer suits:

Often cut slightly looser to allow for air circulation
Lighter fabrics may require different drape considerations
Unlined or partially lined jackets may fit differently

Winter suits:

May be cut with a bit more room to accommodate layers
Heavier fabrics can add bulk, affecting overall fit
Fully lined jackets may require different sizing than unlined summer jackets

Cultural and regional variations in suit fitting preferences:

American style:

Favors a more relaxed fit
Often features a single vent and flap pockets
Tends to have more structured shoulders
Pants typically worn at the waist

British style:

Leans towards a more structured silhouette
Often features double vents and ticket pockets
Common features are higher armholes and suppressed waist

Italian style:

Known for a closer, more form-fitting cut
Often unstructured with minimal lining
Shorter jacket lengths and higher gorges (where the lapel meets the collar)

Asian markets:

Often prefer a slimmer, more fitted style
May account for typically smaller builds

Middle Eastern preferences:

May favor looser fits for comfort in hot climates
Sometimes prefer longer jacket lengths
