Distances From San Antonio, Texas

By the Miles Between Cities Editorial Team  ·  Last updated: October 2026

This hub collects every distance we publish from San Antonio, Texas to the other major cities in our index, in one table, measured the same way every time. San Antonio sits at 29.4628 degrees north and 98.5246 degrees west in the South, and it observes Central Time. From that single fixed point — the internal point published for San Antonio in the U.S. Census Bureau Gazetteer files — the table below gives the straight-line distance to each destination, the driving distance where we have one, an estimated drive time, and a clear label showing whether the road figure was measured via OpenStreetMap routing or produced by our documented estimate. Nothing in the table is blended or averaged between methods: measured means measured, estimate means estimate, and the two are never presented as the same kind of number.

How to Read This Table

Straight-line distance is the haversine, great-circle distance between the two Census coordinates; it is exact for the points chosen and is the best single number for comparing how far apart two cities really are. Driving distance follows roads, so it is always longer — sometimes by a tenth, sometimes by half as much again where terrain or a sparse road network intervenes. Drive time is labelled an estimate everywhere on this site, because no table can know the traffic you will meet, the weather on your day, or how often you stop. Rows marked "No road route" involve a destination with no road connection from San Antonio — an ocean or a roadless stretch intervenes — and for those rows we publish the straight-line figure only, rather than invent a drive that cannot be driven. Where a destination name in the table is a link, a full pair page sits behind it with the comparison table, direction, route summary where routing provided one, and frequently asked questions for that specific journey.

The Closest Cities to San Antonio

The nearest destinations from San Antonio in our index are Austin (74 miles), Corpus Christi (144 miles), Houston (190 miles), Arlington (239 miles), Fort Worth (240 miles). Short hops like these are the trips where driving almost always beats every alternative once door-to-door time is counted honestly, and they are also the trips where the gap between straight-line and road distance matters most in percentage terms: a river crossing, a bay, a range of hills or a one-way city-centre system can stretch a short crow-flies hop into a noticeably longer drive, which is exactly why each row carries both figures side by side instead of a single blended number. For weekend planning, the closest-cities group around San Antonio is the natural starting shortlist — each is close enough for a there-and-back day, and each linked pair page sets out the drive time with the same stop-and-traffic cautions we apply to the longest hauls.

The Longest Hauls From San Antonio

At the other end of the table, the farthest destinations from San Antonio are Honolulu (3707 miles), Anchorage (3168 miles), Seattle (1784 miles), Boston (1766 miles), Portland (1715 miles). The average straight-line distance from San Antonio to all 65 cities listed here is 1083 miles, which gives a quick sense of how centrally or how peripherally San Antonio sits within the national city network: a low average means most of the country is within a moderate drive or a short flight, while a high average — typical of a coastal or corner-of-the-map city — means most journeys start with a long first leg just to reach the middle of the network. Trips at the far end of this table are multi-day drives for almost everyone, and the pair pages treat them that way, with explicit advice about splitting the wheel time, allowing for time-zone shifts where the destination clock differs from San Antonio's, and treating the published drive time as moving time rather than elapsed time. 18 of the routes in this table carry a measured OpenStreetMap routing figure; the remainder are estimates built with the circuity method described on our methodology page, and they are labelled as estimates in every row.

Planning a Trip From San Antonio

Start any plan from San Antonio with the road figure, not the straight line, and then make three honest adjustments. First, add stops: on a drive over three hours, breaks for fuel, food and rest are not optional extras, and they routinely add ten to twenty percent to elapsed time. Second, add the ends: the table measures from the Census point of San Antonio to the Census point of the destination, and your real start and finish — a suburb, an airport, a hotel across town — can add meaningful miles at both ends, especially where San Antonio or the destination spreads over a wide area. Third, add the day itself: rush hours at either end, holiday traffic, summer roadworks and winter weather all stretch the same road miles into very different days. The companion guides on this site — why drive times vary and planning a long drive — work through those adjustments in detail, and the methodology page sets out exactly how every number in the table above was produced, from the Gazetteer coordinates to the routing and estimate methods.
