How to measure

Measure yourself for a suit, one step at a time

Your suit is cut from your numbers, not a size chart. After you order, your account guides you through measuring one number at a time, with a picture for each. Here's what to expect, so you can get ready.

Measuring happens in your account, after you order.

There's nothing to type in on this page. Prefer someone local to help you? Where available, a partner tailor near you takes every measurement instead. It's included in your suit price.

  • About 20–25 minutes
  • 13 numbers to measure
  • A soft tape, ideally a helper
  • Progress saves as you go

Before you pick up the tape

Three rules for numbers that fit

  1. Rule 1: Measure your body, at fixed points

    Every measurement starts and ends at a spot you can find again, like the bone at the edge of your shoulder, your belly button or your wrist bone. Never measure to where you'd like a sleeve, jacket or trouser leg to end. You choose lengths and fit separately, and we apply them for you.

  2. Rule 2: Enter exactly what the tape says

    Enter exactly what the tape says. Don't add room — we add the right amount for your fit. Keep the tape flat, snug and level, without pulling it tight.

  3. Rule 3: A helper makes a real difference

    You can take the easy numbers on your own. Shoulders, sleeves, back length and trouser length are much more accurate with someone holding the tape. On your own? We'll ask you to measure a jacket and trousers that fit you well to check those numbers.

Measure twice, then enter the number. Taking each one twice is the easiest way to catch a slipped tape. If a number looks unusual for your size, we'll ask you right there for a second reading: within ½ inch of the first, we use the average; more than 1 inch apart, we'll suggest asking a helper and we take a closer look.

What to expect

What you'll measure, and what we estimate

First come a few easy questions: your height, approximate weight (only used to estimate your sizes), the sizes you usually buy, seven body-shape pictures, and your fit preferences, like where your trousers should sit. Then you measure. Tap any measurement to see where the tape goes.

You measure 13 numbers

Can't take one of the helper numbers on your own? You can skip it, and we confirm it from your photos and any clothes you measured.

We estimate 10 more

We work these out from your answers and your other numbers, and label them “Estimated — we'll confirm it”. We confirm them before your suit is cut, so there's nothing for you to do here. If we'd like one of them measured, we'll ask you and add it to your steps.

Estimated for you

Measuring with a partner tailor? They take all 23.

Inches, with a centimeter option

Our suit maker works in inches, so that's what we use. Round to the nearest quarter inch and type it as a decimal or a fraction. Only have a metric tape? Switch to centimeters while you measure and we'll convert for you. If a number looks like it was taken in centimeters, we'll ask before converting it.

How to type quarter inches
On the tapeType
15¼15.25 or 15 1/4
15½15.5 or 15 1/2
15¾15.75 or 15 3/4

Optional, and recommended on your own

Measuring clothes you already own

Have a suit jacket or trousers that fit you well? A few numbers from them help protect the parts of a suit that can't be altered later, like the shoulders, sleeves and rise. We compare them with your body numbers.

Lay the piece flat on a table, buttoned, and smooth out any wrinkles. Measure in inches, as described below. Then tell us how it fits: just right, a bit tight or a bit loose. For a jacket, also tell us whether the sleeves are the right length, a bit long or a bit short.

A jacket

  • Shoulder width

    Lay the jacket flat, buttoned. Measure straight across the back from one shoulder seam to the other, where the sleeves are sewn on.

  • Sleeve length

    From the shoulder seam, measure along the top of the sleeve to the end of the cuff. Let the sleeve lie flat; don't stretch it.

  • Back length

    From the seam where the collar meets the back, measure straight down the middle to the hem.

  • Half chest

    Buttoned and flat, measure straight across the front, just below the armpits, from side to side. We double it.

Trousers

  • Inseam

    From the crotch seam, measure down the inside leg seam to the hem.

  • Front rise

    From the crotch seam, measure up the front seam (along the zip) to the top of the waistband.

  • Half waist

    Buttoned and flat, measure straight across the top of the waistband, from side to side. We double it.

Private, and from the neck down

How photos work

If you're 18 or older, we'll ask for three photos at the end. They let us check your posture and spot a tape that slipped, which numbers alone can't show. At a partner tailor appointment, the tailor takes them with your OK.

  1. Photo 1

    Front

    Stand straight facing the camera, arms relaxed at your sides, feet hip-width apart.

  2. Photo 2

    Side

    Turn to your right. Stand naturally — don't straighten up more than usual.

  3. Photo 3

    Back

    Turn your back to the camera, arms relaxed at your sides.

Before you take them

  • Neck down only — we'll help you crop anything above your chin before it's uploaded.
  • Wear a fitted T-shirt and fitted trousers or shorts. Never shirtless or in underwear.
  • Phone at waist height, 2–4 feet away. Use a 5-second timer or ask your helper.
  • Plain background and good light.

Your photos stay private

  • Cropped on your phone. Before a photo uploads, you crop out everything above your chin, so the uncropped photo never leaves your phone.
  • Seen only by the people on our team who check measurements and administrators, plus a partner tailor for photos they take. Never shown to the suit maker or a gift buyer, and never sent by email.
  • Not kept for ever. Your photos are deleted automatically 90 days after your suit is delivered, or when any fit case closes, whichever is later — or sooner if you ask.
  • Under 18? We don't take photos. A partner tailor, or a parent or guardian helping at home, measures instead.

The picture guide below covers all 23 measurements. Your account only asks for the 13 numbers above, one at a time. The rest are here so you can see where a partner tailor measures, and in case we ask you to measure one of them.

Step 0

Before you start

Gather these few things first. It takes about 20 minutes with a helper.

  • A soft tailor's tape

    Use a bendy cloth or plastic tape measure, the kind used for sewing. A metal tape from the toolbox won't follow your body.

  • A helper

    Ask a friend or family member to hold the tape. It's hard to measure your own back, shoulders and arms accurately.

  • Thin, fitted clothing

    Wear a thin, fitted T-shirt and thin trousers or shorts. Take off belts, jackets and bulky clothes, and empty your pockets.

  • A string at your natural waist

    Tie a piece of string or ribbon snugly around your middle, level with your belly button. Several measurements start from it.

  • Stand relaxed

    Stand up straight but natural, arms at your sides, looking ahead. Breathe normally. Don't suck in your stomach or puff out your chest.

  • Measure twice

    Take each measurement twice. If the two numbers are more than ½ inch apart, measure a third time.

  • Exactly what the tape says

    Enter exactly what the tape says. Don't add room — we add the right amount for your fit.

  • Nearest quarter inch

    Record in inches, to the nearest ¼ inch. A decimal or a fraction both work: 15.5 or 15 1/2.

Step by step

The 23 measurements

Go in order. Jacket measurements come first, then trousers. Each picture shows exactly where the tape goes.

Neck

How to measure

Wrap the tape around the base of your neck, just below the Adam's apple, where a shirt collar sits.

Tip: Look straight ahead. Keep the tape snug, not tight, and don't slip a finger under it: we add collar room for you.

Common mistake: Don't measure higher up your neck or tip your head down.

Expected range: 12″ to 24″. Write it down to the nearest ¼ inch, as a decimal or a fraction (15.5 or 15 1/2).

Common mistakes

These are the slip-ups we see most often when people measure themselves.

  • Waist stringBelly buttonNot belt line

    Measuring the jacket waist at your belt line

    Your jacket waist is your natural waist, level with your belly button. That's usually a few inches higher than where you wear your belt or trousers. Measure it at the waist string, and measure your trouser waist separately.

  • Waist string

    A hip measurement smaller than the upper hip

    Your hip (seat) is the fullest part of your backside, so it's almost always the larger of the two. If yours came out smaller, the tape was probably too high or tilted. Stand with your feet together and measure both again.

  • Waist string6–10″

    Writing a leg length for “waist to hip distance”

    This one is short: straight down from the waist string to the fullest part of your seat. It's usually 6 to 10 inches. If you wrote something like 30 or 40, that's a length down your leg. Please measure again.

  • Ending the back length at your belt or tailbone

    Neck to waist (back) ends at the waist string, level with your belly button. Your belt line and your tailbone are lower and add inches.

  • Pulling the tape too tight, or leaving it loose

    The tape should lie flat and snug against your body without pressing in. Don't slip a finger under it or leave a gap. We add the right amount of room for your fit.

  • Letting the tape tilt

    For measurements that go around you, keep the tape level all the way around. A helper can check the back, or use a mirror.

  • Adding a little extra “for comfort”

    Enter exactly what the tape says. The jacket fit and leg shape you chose already decide how much room we add, so extra inches just become extra fabric.

  • Measuring over clothes

    Jeans, belts, phones and wallets can add inches. Measure over a thin, fitted T-shirt and thin trousers or shorts only.

  • Using centimeters or fractions

    The worksheet is in inches: write it however you like, 15.5 or 15 1/2 — both are accepted when you type your numbers in. If a number looks about two and a half times too big, it was probably measured in centimeters. When you enter your numbers in your account, you can switch to centimeters and we'll convert them.

Questions

Measuring FAQ

Where do I enter my measurements?

In your account, after you order. Open your order and choose how you'd like to be measured. The steps walk you through everything, one screen at a time, and your progress saves as you go.

What if I make a mistake?

Don't worry. You can change your numbers as many times as you like until you finalize. If a number looks very different from what we'd expect for your size, we'll ask you to measure it again right away.

After you finalize, we check your measurements before we cut. If something needs another look, we'll tell you exactly which number to re-measure and how.

What should I wear?

For measuring, thin, close-fitting clothes. Take off belts, jackets and sweaters, and empty your pockets. For trouser length, put on the shoes you plan to wear with the suit. For photos, wear a fitted T-shirt and fitted trousers or shorts, never shirtless or in underwear.

Do I need a helper?

We recommend one. You can take your neck, chest, waist, seat, upper arm and thigh on your own, but shoulders, sleeves, back length and trouser length are much more accurate with a second person holding the tape. If you're on your own, we'll ask you to measure a jacket and trousers that fit you well. Or, where available, a partner tailor near you can measure you instead.

Inches or centimeters?

Inches, to the nearest quarter inch. Type it as a decimal or a fraction — 15.5 and 15 1/2 both work. If you only have a metric tape, switch to centimeters while you measure and we'll convert for you.

Why do you need a jacket waist and a trouser waist?

They sit in different places. The jacket waist goes around you level with your belly button. The trouser waist goes where your trousers will sit, which you choose first: high (at your belly button), mid (on your hip bones) or low (below your hip bones). Mixing them up is one of the most common mistakes.

Why do you ask for my weight?

Only to estimate your sizes, so we can spot a number that looks off and fill in the measurements you don't take. We don't use it for anything else.

Should I measure a suit I already own instead?

Measure your body first. If you also have a jacket or trousers that fit you well, measuring them gives our fit team a helpful check on shoulders, sleeves, rise and lengths, the parts that are hardest to alter later.

How long does it take?

About 20 minutes with a helper, or about 25 minutes on your own. You can stop after any step and come back later.

Who sees my photos?

Only the people on our team who check measurements, our administrators, and a partner tailor for photos they took at your appointment. Photos are never shown to the suit maker or a gift buyer, never sent by email, and deleted automatically 90 days after your suit is delivered, or when any fit case closes, whichever is later — or sooner if you ask. Read the details in our fit photos and body data policy.
