XLT and XL share the exact same chest width. The T only changes body length: on Port and Company's tall line, XLT measures 24 inches across the chest, identical to regular XL, but adds 3 inches of extra body length (34 inches versus 31 inches) for a longer torso fit.
Tall sizing exists for one reason: a standard XL fits a 24 inch chest at a 31 inch body length, which is too short for a taller frame with the same chest width. The tall version keeps the chest measurement identical and only stretches the body length, so the fit through the shoulders and chest does not change, only how far the shirt reaches down the torso.

The Exception to Know
Not every brand builds tall sizing the same way Port and Company does. Some tall lines add extra chest room along with the extra length, not just length alone. Always check the specific brand's own chart rather than assuming every tall size follows the same plus-3-inches rule shown above, since this table reflects Port and Company's own construction, not an industry-wide standard.
