Here's a breakdown:

* Texas: Approximately 367 miles of coastline

* Louisiana: Approximately 397 miles of coastline

However, Louisiana has a much larger total coastline when you include the coastline of its numerous bays, inlets, and estuaries. This extended coastline makes Louisiana's total coastline much longer than Texas's.

It's important to specify whether you're asking about general coastline or total coastline when comparing these two states.
