Do Uniqlo Clothes Run Small? (Size Up Or Down)

Uniqlo clothing tends to run small when compared to competitors like Zara and HM. Therefore, for most garments at Uniqlo, you would need to size up.

The Japanese origins of Uniqlo can be said to be a reason for the size issues, but Uniqlo has worked a lot in order to set up a completely unique sizing system for the United States. I will explore the Uniqlo sizing model in this article, but if you directly want to shop their ongoing sale, you can click on the button below for the best prices.

Is Uniqlo True to Size?

No, Uniqlo clothing is not true to size. If you’re buying Uniqlo clothing, it is recommended that you size up.

Most garments from this brand tend to run just a tad bit small. Not enough to cause discomfort, but there can arise a difficulty after the clothes have been through the wash cycle a bunch of times.

Quick Tip

Sometimes the Uniqlo website shows discounts on products only after going through the clearance section and not if you directly go to the product page. Thus, make sure that you always check for your product in the sale section on the Uniqlo website.

Well, the sizing issues at Uniqlo aren’t massive, but a problem can arise due to shrinkage. Most garments tend to shrink a bit in the wash anyway, but the added snugness of the Uniqlo clothing makes it quite unwearable after a few washes unless you get the correct sizing.

However, if you get the right product in the right size, Uniqlo clothing is known to last for a fairly long time compared to its fast-fashion competitors.

What size should you get at Uniqlo?

Just take a look at the product size chart that Uniqlo provides on its website. It will tell you the exact measurements of the clothing that you are looking at.

Compare the measurements given with your own body measurements and you will figure out which size you have to buy at Uniqlo.

Refer to the size chart

To make sure you select the correct size, take your measurements and compare them to the size chart on the Uniqlo website.

You can easily find this chart on the product page. Depending on what country you’re from, this might be called a ‘size guide’ or a ‘size chart’ button.

It’s not rocket science, after all, guys.

Here is a complete breakdown of the different garments available at Uniqlo and what size should you get them in:


The shirts and t-shirts from Uniqlo tend to fit very snug for the average American. Therefore, it can be said that they run small.

This holds true for all the different kinds of shirts that Uniqlo offers. Thus, if you are planning to buy a Uniqlo shirt, I would recommend that you size up by one size in order to get that perfect fit.

This information holds true for the women’s section as well, so you would want to size up when shopping from the women’s section of Uniqlo too.


Uniqlo jeans suffer from the same problem that their tops section does. They are just a tad bit smaller than what the sizing label displays. But some fits of the Uniqlo men’s selection, such as the relaxed fit denim is standard, true to size affair.

This however is a problem of the men’s section only. And even then, it’s not that big of a deal as you can just go one size up to get a better fit.


Uniqlo jackets are pretty much true to size for most people. The size chart will help you in finding out the detailed measurements of the jacket, but in my opinion, you should not size up or down when buying a Uniqlo jacket as they do not run small.

The same goes for the women’s section too, you should not go one size up or one size down when buying a jacket from the women’s section at Uniqlo.

Sweatshirts and hoodies

The hoodies and sweatshirts offered by Uniqlo tend to run small. They are also prone to shrinkage, and therefore it is recommended to size up when buying a Uniqlo sweatshirt.

Compared to the rest of the fast-fashion brands such as HM and Zara, Uniqlo makes their hoodies really slim. So there really is no point in going for your actual size, as the piece is just not going to fit you after some time.

Is Uniqlo sizing the same in every country?

No, Uniqlo sizing is not the same in every country. For example, there is no XXS size in Japan, but you can easily find it in the US.

There are a lot of differences in sizing in the US and the EU too. So, what’s the solution?

You just have to check out the size guide of the product that you are buying.

Uniqlo has worked a lot to simplify its sizing system for each location. Take advantage of this and get the garment that fits you perfectly.

Does Uniqlo Make Plus-Size Clothing?

Yes, Uniqlo makes plus-size clothing. It has a separate big and tall range that goes up to 3XL.

The sizing, unlike some other stores, is actually plus size. The fit on most materials is great and it doesn’t look like you are wearing a tent, which is something that most customers look for.

The collection is not as big as you would want from a global brand (no pun intended), but still, something is much better than nothing.

You can avail yourself of the plus sizes at Uniqlo for both men and women at the official Uniqlo website as well as a large number of offline stores.
