This guide helps cut through the clutter with conversions, fitting tips, and recommendations for certain brands to make sure you (or whoever you are buying for) get it right the first time.

Why shirt fitting is not one-size-fits-all

Not all shirts for men and women are built the same—not just in labels, but in shape, length and fit. Here is what actually changes:

  • Cut - women's shirts typically nip in at the waist; men's shirts are cut straighter. 

  • Length - women's shirts cut about 2-3 inches shorter (if you're going to tuck, it's not an issue; if you're tall it could be!)

  • Sleeves - men's sleeves are usually about 1-2 inches longer. 

  • Shoulders - men's shirts have shirt shoulder seams that are broader.

A real life example: a men's Medium and a women's Large have similar chest measurements, but the women’s version will be slightly shorter and have a little bit of nip.

Advice to Get the Fit Right (Every time)

1. Brands Have Different Rules

Nike, H&M, and Uniqlo all size differently. Things to check before purchasing:

  • Find the brand's size chart (chest/waist/length will help)

  • If you are between 2 sizes look for "unisex" options.

2. Body Type:

  • Slim build? Go with the exact conversion.

  • Curvy or athletic? Going with the women's shirt you will want to size up for comfort.

  • Tall? Typically men's shirts are longer (great for tucking).

3. Measure Before You Buy

You will need a soft tape measure. You will need to check:

  • Chest (fullest part under arms)

  • Waist (narrowest part)

  • Sleeve (shoulder seam to wrist)


Final Tip: Stop Guessing, Start Measuring

Sizing labels are unreliable. Measurements are straightforward. Before you purchase:

1. Compare numbers, not just S/M/L. All will look the same on the hangtag in a store.

2. Read reviews (someone probably mentioned fit).

3. If all else fails, go larger—you can take it down but not up.
