Gildan, Bella+Canvas, and Comfort Colors all currently make and publish verified 4XL specs. Gildan's 5000 fits a 58-60 inch chest in 4XL. Bella+Canvas's 3001 measures 30 inches laid flat (about 60 inches around) in 4XL. Comfort Colors's 1717 measures 29 inches laid flat (about 58 inches around) in 4XL. All three ship as blanks we can print on, or you can buy them plain using the links below. Every number here comes from the brand's own spec sheet, not a guess.
Verified 4XL Specs, Brand by Brand
| Brand and Style | 3XL Chest | 4XL Chest | 4XL Length | Measurement Method |
|---|---|---|---|---|
| Gildan 5000 | 54-56 in | 58-60 in | 34 in | Fits-chest circumference |
| Bella+Canvas 3001 | 28 in flat | 30 in flat (~60 in around) | 34 in | Laid flat, double for circumference |
| Comfort Colors 1717 | 27 in flat | 29 in flat (~58 in around) | 33.5 in | Laid flat, double for circumference |
Gildan publishes fits-chest circumference, meaning you measure around the fullest part of the body. Bella+Canvas and Comfort Colors publish laid-flat measurements instead, so double the flat number for an apples-to-apples comparison to Gildan. See our full XXXL and XXXXL size chart for the complete measurement breakdown, including sleeve length and the 3XL row.
Brands We Could Not Verify in 4XL
We checked Hanes, Next Level, and Port and Company today for a current 4XL spec sheet. Hanes and Next Level's official size-chart pages returned an access error when fetched live, and we could not confirm current 4XL availability or measurements for either brand as a result. Port and Company's plus-size specs were not verified in an earlier check either. We are not listing measurements for these three brands because we could not confirm them against a live manufacturer source today. If you specifically need one of these brands in 4XL, confirm current availability directly with the brand before ordering.
Fit Differences at 4XL
Gildan runs boxy at every plus size, so its fits-chest circumference numbers tend to feel the most generous and forgiving of the three verified brands. Bella+Canvas runs slimmer and more fitted even at 4XL, which is why plus-size buyers sometimes size up or pick a boxier brand for extra room through the body. Comfort Colors sits between the two, and its official sheet states a 2 inch tolerance on both dimensions because the fabric is garment-dyed after construction and shrinks slightly during that process.
What About Women's XXXXL?
Most of the "women's xxxxl" search demand is actually looking for a shirt that fits a plus-size body, not a shirt cut specifically for a woman's frame. None of the three brands verified above publish a women's-specific cut at 4XL. The unisex 4XL specs in the table are what women shopping this size range typically order today. We cover what is and is not verified for women's-specific plus cuts in a companion chart, including which brand's plus fit gets closest to a true women's cut.
Where to Buy Blank 4XL Shirts
We print custom orders on these same plus-size blanks. If you just need plain shirts with no printing, here is where to find each verified brand in 4XL. As an Amazon Associate, we earn from qualifying purchases.

How to Measure Before You Buy
Wrap a soft tape measure around the fullest part of the chest, under the arms and across the shoulder blades, keeping the tape level and snug but not tight. Compare that number to the Gildan row above directly, or double a Bella+Canvas or Comfort Colors flat measurement first. For a full walkthrough with photos, see our how to measure chest for a t-shirt guide.

Which brand's 4XL fits the biggest?
Gildan runs the most generous at 4XL because it cuts boxy at every size. Bella+Canvas runs slimmer and more fitted even at its largest sizes. Comfort Colors sits between the two, with a 2 inch tolerance built into its official spec because of the garment-dye process.
