Frequently Asked Questions
Common questions about the South Dakota State Flags state flag — including history, display rules, sizing, and where to buy.
Tidmore Flags carries authentic, US-made South Dakota state flags in nylon and polyester, available in multiple sizes for homes, businesses, and institutions.
For a 20-foot pole, a 3x5 ft flag is standard. For a 25-foot pole, go with 4x6 ft. For 30-35 feet, use 5x8 ft. South Dakota's Black Hills and open plains experience very strong winds — size conservatively and use a heavy-duty pole and hardware rated for high wind loads.
For South Dakota's extreme plains and mountain climate, heavy-duty polyester is the top recommendation. South Dakota experiences brutal winters with sub-zero temperatures and blizzards in the east, and strong Black Hills winds year-round in the west. Polyester maintains flexibility in extreme cold and handles high winds better than standard nylon.
South Dakota's extreme weather — bitter cold winters, blizzards, strong plains winds, and intense summer UV — means even a quality heavy-duty flag flown daily typically lasts 4 to 9 months. In the most exposed locations like the open Badlands or Black Hills ridgelines, flags face some of the most demanding conditions in the continental US.
Yes, but the US flag must always fly on top when both are on the same pole. On separate poles of equal height, they can fly at the same level with the US flag to its own right (observer's left) and both flags the same size.
For South Dakota's demanding outdoor conditions, a sewn South Dakota flag is strongly recommended. The sun motif with the state seal requires quality construction to maintain detail and color integrity in South Dakota's extreme cold, wind, and UV conditions.
South Dakota's flag includes the nickname The Mount Rushmore State because South Dakota is home to Mount Rushmore National Memorial — the iconic granite sculpture in the Black Hills featuring Presidents Washington, Jefferson, Theodore Roosevelt, and Lincoln carved by sculptor Gutzon Borglum between 1927 and 1941.
In South Dakota, use hardware rated for extreme cold and high wind loads throughout. Standard plastic components crack in South Dakota's sub-zero winters. Use stainless steel or brass snap hooks and a heavy-duty polyester halyard rope. Set ground poles to at least 48 to 60 inches deep given South Dakota's frost depth and the need for stability in high winds.
For indoor ceremonial display, use a pole sleeve flag on an 8-foot pole with a base and ornament. Gold fringe is the traditional finish. South Dakota's blue flag with the gold sun motif and state seal looks sharp in formal settings like courtrooms, schools, and government buildings.
Retire your worn South Dakota flag by burning in a dignified ceremony. South Dakota VFW posts, American Legion chapters, and fire departments hold regular flag retirement ceremonies throughout the state.
