5 Simple Steps on How to Measure Chest Size

Step 1: Gather Your Tools

First things first—grab a flexible tape measure and a trusted friend to assist you. You'll want to ensure an accurate measurement, so avoid using a ruler or a stiff measuring tape.

Step 2: Find Your Starting Point

Stand up straight with your arms by your sides. Wear a well-fitted shirt (or no shirt at all) to get the most accurate measurement. This will help prevent any bulk from affecting your measurement.

Step 3: Measure Across the Fullest Part

Wrap the tape measure round the fullest part of your chest, positioning it horizontally across your nipples. Make sure the tape is parallel to the ground and snug against your skin, but not too tight. You want it to be comfortably snug, allowing for natural breathing. You should be able to get your fingers between the tape and your body.

Step 4: Take the Measurement

Have your friend check the measurement where the beginning end of the tape meets the rest of it. Make sure the tape is level all the way around your chest. Record the measurement in inches or centimetres—whichever you prefer.

Step 5: Double-Check and Repeat

To ensure accuracy, it's a good idea to take a couple of measurements and then average them out. Double-check that the tape is positioned correctly and that you're not holding your breath or puffing out your chest, as this can skew the results.

And there you have it - you've now mastered how to tie a bow tie. Just one practical tip: practise how to tie a dickie bow well ahead of the event (and have a handy ready-tied option in your tuxedo pocket, just in case). For some formal occasions, you might prefer to try a Windsor knot or tie a Half Windsor. However, when it comes to black tie events, the best tie is undoubtedly bowed.

Choosing the Right Shirt for Your Chest Size

Now that you know your measurements, you’re a step closer to finding the ideally fitted dress shirt, waistcoat or jacket. When choosing the right shirt for your chest size, the way it fits is everything. Here’s what to do:

- Choose shirts labelled with your chest measurement or size range to ensure a snug yet comfortable fit.
- Opt for styles with some stretch or room in the chest area to accommodate movement.
It's better to go slightly larger and tailor down than to squeeze into a shirt that's too small.

Also, remember that your chest size doesn’t always determine your shirt fit size. For example, a 38-inch chest could mean you’re a medium in the classic fit range but a small in the slim fit range.

Here are a few other shirt fit dos and don’ts.

Outfit Do's

- Opt for Tailored Fits: Look for shirts labelled as ‘tailored’ or ‘fitted’, as they're designed to provide a sleek silhouette.
- Consider Stretch Fabrics: Fabrics with a bit of stretch can accommodate variations in chest size while maintaining a flattering fit.
- Experiment with Different Necklines: V-neck or scoop neck shirts can elongate the torso and draw attention away from a larger chest.
- Focus on Vertical Patterns: Vertical stripes or patterns can create the illusion of a slimmer chest area.


Outfit Don'ts

- Avoid Baggy Styles: Oversized or boxy shirts can add bulk and make your chest appear larger.
- Steer Clear of Tight Fits: While you want a snug fit, avoid shirts that are overly tight across the chest, as they can restrict movement and appear unflattering.
- Say No to Horizontal Stripes: Horizontal stripes or patterns can visually widen the chest area, so it's best to avoid them.
- Skip High Necklines: High-necked shirts can emphasise a larger chest, so opt for styles with lower necklines instead.


By following these dos and don'ts, you'll be better equipped to select shirts that flatter your chest size and enhance your overall appearance. For more details on our fits, check out our shirt size guide.
