Big and tall covers two different things, not one. Tall sizing adds body length at the same chest width. Big sizing adds chest width at standard body length. Port and Company's tall line runs LT through 4XLT, each one matching its letter-equivalent regular size in chest width and adding a consistent 3 inches of length. The regular Big line runs all the way to 6XL for chest width alone, at standard length.

Tall or Big: Which One Do You Need
If the chest fits but the shirt rides up or looks cropped, tall sizing is the fix, it keeps the same chest width and adds length. If the shirt is long enough but tight across the chest, big sizing is the fix, it adds chest width at the same standard length. Some people need both, but Port and Company's own catalog for this garment only publishes the tall line up to 4XLT, so past that point, only the regular Big sizing (with standard length) is available through 6XL.
