How to Measure Yourself for DOAC Merch

Before you scroll to the size chart, grab a soft measuring tape and a shirt that fits you well. Lay the shirt flat on a table and take these three measurements:

Chest width: Measure 1 inch below the armpit, from side seam to side seam. Double this for your full chest circumference.
Body length: From the top of the shoulder seam (where it meets the collar) straight down to the bottom hem.
Sleeve length: From the shoulder seam to the end of the sleeve cuff.

For hoodies, also measure the shoulder width across the back from seam to seam. I've found that many people overestimate their size because they don't account for the fabric drape. A 40-inch chest doesn't automatically mean size Large - it depends on whether you want a slim or relaxed fit.

Using a Well-Fitting Shirt

If you don't have a measuring tape, use a shirt you love the fit of. Check its care tag for the size label, then compare that to the size chart below. This works because your "perfect fit" shirt compensates for your personal preferences. Just remember that unisex sizing runs differently than men's or women's specific cuts.

Diary of a CEO T-Shirt Size Chart and Fit Tips

All Diary of a CEO tees are unisex, 100% ring-spun cotton, and pre-shrunk. The standard tee has a modern, not-too-slim, not-too-loose cut. Here's the size chart (measurements in inches for chest width, body length):

Size	Chest Width (half)	Body Length	Sleeve Length
XS	17.5	26	7.5
S	19	27	8
M	20.5	28	8.5
L	22	29	9
XL	24	30	9.5
2XL	26	31	10

Fit tip: If you're between sizes, size down for a fitted look or size up for extra room. The tee does shrink slightly after the first wash, so if you're on the edge, go with the larger size. For a 5'10", 170-pound male with a 40-inch chest, size M is spot-on for a tailored fit; size L gives a relaxed feel.

Choosing Between Standard and Premium

The Premium Weight Tee uses 6.5 oz fabric (vs. the standard 5.3 oz) and has a slightly wider chest and longer body. If you want a sturdier shirt that holds its shape after many washes, go premium. The fit is similar, but some customers say it runs a half-size larger - check the individual product page for that specific chart.

Diary of a CEO Hoodie Size Guide: Regular vs Oversized

Hoodies are where the fit decisions get tricky because you have two distinct cuts.

Regular Hoodie Fit

The regular hoodie is a classic midweight fleece with a standard cut. It fits close to the body without being tight and has a ribbed hem and cuffs. Use your chest measurement and match it to the size chart (same chest widths as the tees above but longer body - add 2 inches to length). This hoodie is ideal for layering under a jacket or for a clean, athletic look.

Oversized Hoodie Fit

The oversized hoodie is deliberately roomy: dropped shoulders, wider sleeves, and a cropped body. The chest width is about 4 inches more than the regular at each size, and the body length is actually 1-2 inches shorter. For example, a regular L has a 22-inch chest half and 31-inch length; an oversized L has a 26-inch chest half and 29-inch length. If you want that streetwear vibe, choose your true size - it's meant to be big. If you're on the fence, go one size down from your regular tee size for a less extreme look.

Which should you pick? If you're 5'10" and 170 pounds, a regular hoodie in L is snug but comfortable. For the oversized, size M gives a relaxed but not swamping fit. The oversized hoodie is popular for lounging and casual wear, but it can feel bulky under a coat.

Common Fit Questions for Unisex Styles

What's the difference between unisex and men's sizing?

Unisex sizing is based on men's measurements but with straighter sides and slightly narrower shoulders. Women often size down one size from their usual women's size. For example, a woman who wears a women's M should try unisex S for a similar fit.

How do I know if I need a tall size?

There are no tall sizes currently. If you're over 6'2", the body length may be short. The oversized hoodie runs shorter, so stick with the regular hoodie for more length.

Will the shirt shrink?

Yes. Pre-shrunk cotton can still shrink 2-3% in the first wash. Wash in cold water and tumble dry low to minimize shrinkage. If you're between sizes, go up to account for this.

Can I layer a hoodie over a tee?

Yes, but order the hoodie in the same size as your tee for a comfortable fit. If you want the hoodie to be the outer layer, consider one size up.

Choosing the Right Size: Tips to Get It Right the First Time

Here's a step-by-step approach to avoid size mishaps:

1. Measure a well-fitting shirt at home - chest, length, sleeve. 2. Compare to the size chart on the product page (each item may have slight variations). 3. Consider your desired fit - slim, regular, or oversized. 4. Factor in shrinkage - if you're between sizes, go larger. 5. Read customer reviews for real-world feedback on fit. Many reviews mention height and weight, which helps.

I always tell customers: when in doubt, order two sizes and return the one that doesn't work. But to save shipping costs, use our virtual fit finder tool on the product page - just enter your height and weight, and it recommends a size.
