Measuring Guide

Having measurements taken with a measuring tape is preferable.  However, if you don't have a measuring tape or personal tailor at home, we recommend the Sizer app with two main notes:

- The app really does work but wear underwear when taking the body scan.  Clothes will increase your sizes.

- The app measures in-seam to the floor whereas we measure to where the the trouser will sit.  We recommend you minus 1-2 inches off the app's  inseam measurement.

To take measurements you’ll want a soft material measuring tape.  The all important measurements we will need are:

Top Half:


Firstly, no chunky clothes when measuring!  Shirtless, or a thin t-shirt/shirt.

Starting with your arms raised, wrap the measuring tape around the widest part of your chest.

Drop your arms to your side, making sure the measuring tape is snug but not stretched.

Keep the breathing relaxed, no puffing the chest out!

The number, in inches, where the tape measure meets is your chest size.

Combine with letter corresponding to your height for jacket length.

5'5 - 5'7
5'7 - 6'2
6'2 - 6'6


For your shirt, wrap the measuring tape around your neck at the height where the collar would normally rest - just below your Adam's apple.

Hold your neck straight, now looking up or down. The tape should be resting lightly on the skin, not squeezing it.

Hold one finger under the tape measure to ensure some room for comfort. If you don’t measure with a finger under the tape measure, simply add half an inch to your final measurement.

Bottom half:


Wear your suit shoes when measuring for suit trousers. Your shoes change the way you stand and alter your height, so you need to wear them when taking your measurements.

Measure your waist where you’d have your suit trousers sit.  Remember these are not your jeans so will sit slightly higher.

Position the tape measure where you’d normally wear a belt then wrap it around your waist.  Don’t breathe in while taking this measurement, nice and relaxed.

 The number, in inches, where the tape measure meets is your waist size.


Get your inseam by measuring from your crotch to the bottom of your ankle.

Position the tape inside your leg as high as it will go. This should be where your leg meets your groin.

Then, slide the tape down your leg (if possible get someone else to hold the tape down) until it meets the bottom of your ankle/where you would like the trouser to sit.

The number in inches is your inseam length.

N.B. You can take this measurement from a pair of trousers that you own which fit you well.

Lay the trousers out on a flat surface, outer leg side down. Fold one leg out of the way and measure the inseam from ankle up to where the trouser meets at the groin.
