Is also important that you measure yourself so you can ensure that you get the correct jersey in the correct fit. Different Jersey types have different sizes in terms of chest width. Therefore by measuring yourself correctly you ensure that you get the best fitting jersey for yourself in this guide will show you how to measure yourself and we also show you different types of Jersey size from the current NBA Jersey size all the way through to the vintage jerseys which were made by sand knit. However, we will look at the most recent jerseys.

How to measure yourself for a NBA Jersey

The most important action you must take before you purchase is a jersey is to measure yourself and it takes two seconds to do. The reason why this is the most important step in the process is that each manufacturer may vary their jerseys slightly when it comes to chest size. For instance, I would personally be a Large in a Nike Jersey but I would be an XL in an Adidas Jersey. Therefore, it is best to know your sizes so you’re not disappointed when the jersey turns up. There is nothing worse than not being a happy with a jersey.

Measure from the sternum
You’ll need a soft tape measure

The equipment that you will require for taking the measurement is a soft tape measure, yourself and potentially an assistant. The key here it to place the tape measure on your sternum and take the tape measure round the widest section of your chest. This will then give you the size chest you have. In the example below, I measure myself and I have a 48 inch chest.

Nike NBA Jersey Size 2017 – Present

Nike took over from Adidas as the official manufacturer of NBA jerseys in 2017 and have a specific sizes for their jersey. It is important to remember that there are different types of jersey (if you don’t know the different types then read Adys article on the types) and that the Swingman jersey is slightly shorter than the authentic jersey. The sizes of the Nike manufactured jerseys are listed below.

The Nike Authentic jerseys are slightly longer in length than the swingman or replica jerseys. This is because the authentic jerseys exactly replicate what is worn on the court by the players. The jerseys that the NBA players play in have slightly longer length. If you are thinking of being an NBA Nike jersey then visit Fanatics who the official retailer of the NBA.

Reebok NBA Jersey Size 2001 – 2006

Reebok first started making jerseys for some teams in 2001 and made all the jerseys in the NBA by 2006. However, the NBA for some reason, that I do not know at this time but I will find out, had manufacturers for different teams. In fact Reebok restarted the trend of all teams having one jersey manufacturer in 2006.

The jerseys worn by NBA players which from 2007 onwards have been manufactured by Adidas and then Nike, have been known as Authentic jerseys. However, Reebok called the jerseys worn by NBA players, pro cut jerseys.

James

A basketball court was built in my local park and at 15 years of age I fell in love with basketball. A late joiner to the game, I have played every season since. Some Indiana friends bought me some Pacers gear for my 17th birthday, and I have supported them ever since (who wants to follow the crowd). I love American sports apparel and the presentation of sports, they do it so well (bar all the advert breaks).
