Dress Shirt 101: How to Measure a Shirt that I Already Own

Jean-Baptiste

The eas­i­est and best way to order a cus­tom dress shirt is to mea­sure a shirt that already fits you well.  Most rep­utable online cus­tom dress shirt mak­ers will pro­vide instruc­tions on how you can mea­sure a shirt that fits you well as opposed to stan­dard ‘off the rack’ siz­ing or tra­di­tion­al body mea­sure­ments.

Before you begin, make sure you have a mea­sur­ing tape, like the one shown below.  Mea­sure your exist­ing shirt per the instruc­tions shown. Do not add any tol­er­ance. These are fin­ished or ‘cut’ mea­sure­ments. The mea­sure­ments pro­vid­ed should be the exact same as the shirt in which it is being mea­sured from. This ensures that you’ll receive a shirt that is a very close clone of the orig­i­nal.

Step 1 — How to Measure Sleeve Length

There are two meth­ods that shirt mak­ers use for mea­sur­ing sleeve length:

Method 1 — The Traditional ‘Off the Rack’ Measurement

This method is sim­pler and what you’re accus­tomed to see­ing on most off the rack shirts.  The dis­ad­van­tage to the sim­plic­i­ty is that the back (yoke) and sleeve length are com­bined which can result in some inac­cu­ra­cies depend­ing on your arm length or back size.

INSTRUCTION:  Lay the sleeve flat on it’s front and mea­sure from the mid­dle of the back (just beneath the col­lar) to the end of the cuff. If this is for a short sleeve shirt, please mea­sure as described. Our tai­lors will deter­mine the cor­rect length if a short sleeve option is select­ed.

Method 2 — Measured from the Shoulder to the Wrist

This method tends to be more accu­rate as the sleeve mea­sure­ment is decou­pled / sep­a­rate from the yoke (back) mea­sure­ment.

INSTRUCTION:  Lay the sleeve flat and mea­sure from the top of the shoul­der to the end of the cuff. If this is for a short sleeve shirt, mea­sure to the desired length — just beneath where the bicep lies is typ­i­cal­ly prefer­able.

Step 2 — How to Measure the Collar

INSTRUCTION:  Lay the shirt flat on it’s back, remove any wrin­kles, and mea­sure from the cen­ter of the col­lar but­ton to the fur­thest edge of the but­ton­hole.

NOTE: If you are inputting a standard collar size from an existing shirt, measure as shown above. Collar sizes on off the rack shirts are commonly upto 0.5″ larger than the listed size.

Step 4 — How (and Where) to Measure the Waist
