A 39 inch chest is a medium chest size. In other words, if you have a 39” chest, then you’re completely normal and likely have nothing to worry about.

Still, many people want to know all the ins and outs of having a 39 in chest and how it compares on a wider scale. So if you want to learn how big or small your 39 inch chest really is, keep reading for all the info.

So, how big or small is a 39 inch chest? Based on my extensive research, a 39 inch chest definitely isn’t small. On the other hand, a 39” chest isn’t big, either. Rather, a 39 in chest is very much a medium size, meaning that many men all over the world have a 39 inch chest.

Now, a 39” chest will definitely look bigger on a shorter person than on a taller person. This is because when you’re fairly short and have a 39 in chest, that chest mass is spread out over a smaller surface area, which in turn makes it look bulkier.

In a similar vein, if you have a muscular 39” chest, that will definitely look better and more aesthetically pleasing than a flabby 39 inch chest.

So as you can see, there’s more to building an impressive chest than just the circumference measurement. Muscle definition plays a massive role in how your pecs actually look and how strong they are (a lean 39” chest has more muscle mass than a fat 39” chest and thus more strength potential).

What size is a 39 inch chest for men?

For men, a 39 inch chest is a medium shirt size in most clothing. If you anticipate that your 39 in chest might get bigger due to resistance training, then you could always size up, especially if you tend to wear slim-fit clothing.

What size is a 39 inch chest for women?

It depends on the brand and the country that you’re in, but in general, a 39 inch chest is considered a size large in women’s clothing and is equal to a size 13 or 14 in most cases.

Should you build your 39" chest as a man?

Since the chest can often be a highly visible body part when you’re wearing a t-shirt, it’s an area of paramount importance for many men. That’s why you see so many guys starting their training week with a chest workout!

But at 39 inches, your chest definitely isn’t small. So is it actually worth your time and effort to make your chest bigger when it’s already decently well developed?

If you love lifting, then I’d say go for it. If you just focus on using good form and progressively increasing the resistance over the weeks, months, and years, then your chest is going to get bigger regardless of whether you want it to or not.

On the other hand, if you want to build your 39” chest because you feel obliged to, then this could lead to unhealthy behaviors such as excessive amounts of strength training and overeating.

I understand that many people are very body-conscious these days (I certainly was when I was younger), but building more muscle doesn’t always solve your problems because some of us are never satisfied. That’s why I like to focus on the enjoyment of my training and let the muscle growth take care of itself.

In conclusion

As noted, there are so many people in the world with a 39 inch chest because it’s a really common chest size! I know that might not be what you want to hear if you want to feel special, but it’s completely fine to blend in sometimes.

And as I said before, you’re in control. You can lose fat and build muscle to make your chest look much better without necessarily making it a lot bigger. That’s the beauty (literally) of strength training.
