3XL size chart: chest, waist and hips
The chest range gets most of the attention, but a shirt also has to fit through the waist and hips. Compare the three numbers together.
| Label | Chest or bust | Waist | Hips |
|---|---|---|---|
| Nike men's XXL | 48.5–53.5123–136 | 43–47.5109–121 | 47–50.5119–128 |
| Nike men's 3XL | 53.5–58136–147 | 47.5–52.5121–133 | 50.5–53.5128–136 |
| adidas men's XXL | 47–51119–130 | 42.5–47108–119 | 46–49117–124 |
| adidas men's 3XL | 51.5–56131–142 | 47.5–52121–132 | 49.5–53126–135 |
| Nike women's 2X | 49.5–52126–132 | 45.5–49116–124 | 54–57137–145 |
| Nike women's 3X | 52–55132–140 | 49–53124–135 | 57–61145–155 |
| adidas women's 2X | 45–48.5114–123 | 39–42.599–108 | 47.5–51121–130 |
| adidas women's 3X | 49–52.5124–133 | 43–46.5109–118 | 51.5–55131–140 |
The same number can land on different labels. A 52 inch chest is an XXL at Nike and Strongsize but a 3XL at adidas, whose men's 3XL starts at 51.5 inches. Nike's men's 3XL starts two inches higher, at 53.5.
3XL or 3X?
These are different lines, even at the same brand. Nike's men's 3XL lists a 53.5–58 inch chest and 50.5–53.5 inch hips. Its women's 3X lists a 52–55 inch bust and 57–61 inch hips. The women's line runs smaller at the top and larger at the hips, so one label can't stand in for the other.
Where 3XL sits on each chart
On adidas's standard men's shirts and tops chart, 3XL is the last label, ending at 56 inches. Nike's men's chart has one more size above it, and Strongsize runs on to 8XL. If a 3XL is close to your limit at adidas, compare a brand with more room above it before you order.
Moving between sizes
Nike's men's chest range rises 4.5 to 5 inches from XXL to 3XL. adidas leaves a half inch gap between those two labels, and Strongsize leaves a full inch. A measurement that lands in a gap gets the larger size in the tool above.
Chart measurement or shirt measurement?
Gildan's 5000 T-shirt lists a 3XL at 28 inches across the chest laid flat. That is the shirt itself, so don't compare it directly with your chest measurement.
Across, not around: doubling 28 gives 56 inches around the shirt. BELLA+CANVAS lists its 3001 T-shirt at the same 28 inches. Each label up the Gildan chart adds 2 inches of flat width, so an XXL is 26 inches and a 4XL is 30.
Check the length too
Strongsize lists its 3XL T-shirt at 33.75 inches long in regular length and 36.75 inches in longer length. If length matters to you, compare it with a shirt you already own.
