A Texas Mileage Chart is a spatial tool used to quickly look up highway driving distances between the state’s major cities. Because Texas spans a massive 268,597 square miles, these grid-style matrices are heavily relied upon by truck drivers, road-trippers, and state agencies to calculate travel logistics. The Official TxDOT Mileage Grid
The most authoritative mileage chart is published by the Texas Department of Transportation (TxDOT) on the Texas Official Travel Map. It uses a triangular “cross-reference” index grid:
How to read it: You locate your starting city on the vertical axis and your destination city on the horizontal axis. The number where their row and column intersect is the distance in highway miles.
Road miles vs. Straight lines: Official state charts represent actual ground/highway miles, whereas quick online tools often calculate “as the crow flies” straight-line distance, which can be significantly shorter. Overview of Common Distances Between Major Texas Cities
