Blue Lock Classic T-Shirt

This is the baseline for the whole size guide. The Blue Lock Classic T-Shirt is the most popular piece in the store, and it's easy to see why. Built from 100% ring-spun cotton with a pre-shrunk finish, it keeps its shape wash after wash. The relaxed unisex fit means it runs a bit roomy through the chest and shoulders, which is ideal if you prefer a casual streetwear silhouette.

Here are the actual garment measurements (in inches) for the Classic Tee:

If you're between sizes, we recommend sizing down for a fitted look or sizing up for extra room. And for a whole range of tees, check out Blue Lock's t-shirt collection - you'll spot the same sizing across all of them.

Blue Lock Premium Hoodie

Next up is the Blue Lock Premium Hoodie, a $49.99 choice for colder days. This hoodie plays without too much bulk, and it runs true to size. The thick fleece interior keeps its structure, so you won't end up with a stretched-out neckline after a few wears. The fit is slightly more tailored than the tee, especially through the waistband. If you plan to layer a hoodie under it or you're grabbing one for a friend who likes a baggy look, go up a size. The Premium Hoodie uses the same measurement table as the Classic Tee, with one key difference: the body length runs about an inch longer, so you're covered on those diving header celebrations.

Blue Lock Polo Shirt

The Blue Lock Polo Shirt at $34.99 is a different story. Its tailored fit is more athletic, with a slimmer cut through the torso. This one runs snug - if you're between sizes on the chart, grab the larger option. The polo's fabric has a bit of stretch, but it's not a forgiving knit, so measure close to your chest. For reference, a customer who wears a medium tee usually reaches for a large in this polo. The sleeves are also a touch shorter, which gives that sharp, soccer-coach look that pairs well with the Blue Lock crest.

Blue Lock Tank Top

And for summer training or back-to-school season, the Blue Lock Tank Top is the loosest of the bunch. It's designed with a wider armhole and more drape, so you can stick with your usual size or downsize for a trimmer look. The tank runs true to size compared to the Classic Tee, but the straps are set a bit wider so it won't dig into your shoulders. At $19.99, it's an easy pick-up if you want the Blue Lock aesthetic without the sleeve commitment. Just check the chest measurement on the table below - the tank uses the same chest numbers as the tee, but the body length is 2 inches shorter.

Where to Buy

You can grab any of these pieces from the official Blue Lock store. Head over to any product page and you'll find a "Size & Fit" tab that shows the exact Blue Lock merch size chart for that item. If a style is sold out, the store's restock alerts can help you jump on it the moment it's back. And if your order doesn't fit? The store offers 30-day returns and exchanges, so there's minimal risk when you're guessing based on another brand's sizing.

Before you add to cart, measure a shirt you already own and compare it to the tables above. That's the fastest way to lock in a perfect fit - and it's exactly what the store's customer-service team recommends. For a complete look at every item currently available, explore the full collection and filter by category. The sizing guidelines stay consistent across new drops, so once you know your number, it sticks.

FAQ

How does Blue Lock merch sizing compare to regular streetwear?

Most Blue Lock apparel runs true to size compared to standard US sizes, but the Classic T-Shirt and Tank Top have a relaxed unisex fit that can feel one size bigger. The Polo Shirt runs slim, so size up if you're between measurements. The Premium Hoodie is true to size but slightly longer, so go up if you prefer a cropped vibe.

Are the Blue Lock Classic T-Shirts pre-shrunk?

Yes, the Classic Tee is made from 100% ring-spun cotton that is pre-shrunk. That means the fit you get on day one is the fit you'll have after washing, as long as you follow the care label and avoid high-heat drying.

What if I order the wrong size from the official Blue Lock store?

You have 30 days from delivery to exchange or return items that haven't been worn or washed. The return process is straightforward: contact support through the store, and they'll send you a prepaid label. Exchanges are free, and you can request a size swap without any restocking fee.

Can I find a Blue Lock merch size chart in centimeters?

The official store's size guide displays both inches and centimeters on the product pages, so you can toggle based on your preference. This guide uses inches for the tables above, but the store's overlays are just as accurate.

Which Blue Lock item has the most forgiving fit?

The Tank Top is the most forgiving because of its wider armholes and looser drape. If you're between sizes on the Classic Tee, sizing up still gives you a comfortable, street-ready look without looking baggy. - -
