Where a source gives inches only, cm is converted at 2.54 cm per inch and rounded to the nearest cm.
How big is a 5XL shirt?
By the body it fits, measured around the fullest part of the chest:

A PC61 5XL is sized for a chest about 4 inches smaller than a Gildan or Bella+Canvas 5XL. On PC61, a 62 inch chest is a 6XL (61 to 63 inches, same source).
What does a 5XL measure laid flat?
These are the garment's own measurements, taken with the shirt lying flat. Double the laid-flat chest for an approximate circumference.

Bella+Canvas 3001 and PC61 both measure 32 inches laid flat and 35 inches long at 5XL, about 64 inches around the garment (32 doubled). PC61 builds that garment for a 58 to 60 inch chest, so it runs roomier per label than its chest range suggests (derived from the PC61 rows above).
Is XXXXXL the same as 5XL?
Yes. XXXXXL and 5XL are the same size in two label styles (source: theloyalbrand.com/blogs/blog/shirt-sizes-in-numbers, letter size to X-count table).
How does 5XL compare with 4XL and 6XL?

PC61 also makes a 6XL for a 61 to 63 inch chest (155 to 160 cm converted; sanmar.com PC61 Size Chart, fetched 2026-09-29). Neither our Gildan chart nor the fetched Bella+Canvas chart lists a 6XL, so no 6XL row is given for them.
Which common blanks come in 5XL?
Gildan 5000, Bella+Canvas 3001 and Port & Company PC61 all list a 5XL (sources above). Comfort Colors 1717 is not made in 5XL (source: theloyalbrand.com/blogs/blog/shirt-sizes-in-numbers, plus-range comparison table).
