Is XXXXL the same as 4XL?
Yes. XXXXL and 4XL are two ways of writing the same label. What that label fits still depends on the brand.

Questions and answers
What size is 4XL in numbers?
There is no single number. Calvin Klein's plus size 4XL tops and dresses are listed as US 16–18, while Nike lists its women's 4X as US 30W–32W. Check which line your label belongs to.
What chest size is a men's 4XL?
Nike's men's 4XL fits a 58–63 inch chest. Sizes vary by brand, and adidas's regular men's chart stops at 3XL.
Is 4XL the same as 4X?
Not always. 4X is usually a women's plus line label, and 4XL can be a men's or women's label. They can cover very different measurements, so compare the chart for the item you are buying.
What if I am between two sizes?
Nike advises ordering the smaller size for a tighter fit or the larger size for a looser fit. If your chest and waist point to different sizes, Nike says to go by your chest.
